Camden CX-94S-12LS 1200 Lb Surface Mount Gate Lock
The Camden CX-94S-12LS is a surface-mount magnetic lock engineered for outdoor gate and perimeter-barrier applications in access control deployments. With 1200 lbs holding force and integrated lock sensor plus relay module, it eliminates the need for external door-position monitoring hardware — your access control panel receives status feedback directly from the lock without additional wiring or breakout modules. Field-selectable 12V DC or 24V DC operation matches any standard access power supply, reducing the need to maintain separate inventory SKUs across different voltage environments. This lock is built for unattended gate access: parking lots, warehouse perimeters, storage yard barriers, and tenant-gated facilities.
Key Features
- 1200 Lb Holding Force: Magnetic lock rated for 1200 lbs — sufficient for single-leaf and light double-leaf gate applications up to standard commercial widths. Heavy-duty holding power eliminates mechanical throw-bolt reliance on gated perimeters.
- Integrated Relay Feedback: Built-in lock sensor and 1A@30V DC relay module provide status continuity to your access control panel with zero external hardware. Reduces wiring clutter and single points of failure in distributed gate systems.
- Field-Selectable Voltage: 12V DC or 24V DC operation — no separate SKUs needed. Match your existing access control power supply (typically 24V DC for panel-powered locks) or 12V DC auxiliary supplies on retrofit projects.
- Surface Mount Design: Mounts directly to existing gate frames without structural drilling or welding. Conduit-fitting inlet accepts standard outdoor-rated conduit for weather-sealed wire runs.
- Operating Range: −15°C to +50°C (5°F to 122°F) — covers most North American climates including freeze-thaw cycles and high-temperature exposure common to unshaded outdoor installations.
- Compact Footprint: 2.5″H × 8″W × 1.625″D fits standard gate latch cutouts without frame modification or secondary mounting hardware.
- Low Power Draw: 500mA at 12V DC or 250mA at 24V DC — verify your power supply amperage budget before installation, but typically a non-issue on properly sized access control supplies.
In outdoor gate applications, the integrated relay is the operational differentiator. Most magnetic locks require a separate magnetic door-position switch — a separate device, separate wiring, separate entry point in your access control panel. The CX-94S-12LS consolidates lock status into the lock itself. On a 10-gate parking-lot perimeter, that's 10 fewer switches to wire, 10 fewer zone assignments in your panel, and 10 fewer points of corrosion on outdoor terminals. The relay contact is rated 1A at 30V DC — sufficient for direct panel input on any commercial access control system (Honeywell, Salto, Bosch, HID, Lenel) without intermediate relays or field-wiring breakout modules.
Field voltage selection (12V vs. 24V DC) is a real installation convenience on retrofit projects. Many older gate operators run 12V DC auxiliaries; newer access control systems standardize on 24V DC. Rather than sourcing the right model, you receive one SKU that adapts to your power architecture. This reduces lead-time friction when integrating into mixed-voltage sites. Voltage is set via internal jumpers — documented in the datasheet, set once at installation, no field-reconfiguration needed after deployment.
Surface-mount installation is straightforward on existing gate hardware. Unlike embedded strike systems, the CX-94S-12LS bolts onto the gate frame and gate post without structural modification. The conduit-fitting inlet is essential: outdoor installations must run field wiring through NEMA 3R or equivalent conduit to survive rain, UV exposure, and temperature cycling. Plan for ½″ or ¾″ conduit termination and weather-sealed fittings — standard practice on perimeter-access infrastructure. Current draw is moderate (500mA @ 12V, 250mA @ 24V), but verify your power supply has adequate amperage if powering multiple gates from a single supply.
The lock is warranted as a manufacturer product, meaning defects within the warranty period are covered through normal channels. Typical gate-lock deployments see 5–10 year service life with minimal maintenance. The integrated relay eliminates the external switch failure mode; internal relay wear is negligible on properly powered circuits. Pair the CX-94S-12LS with a surface-mount armature plate (typically included or available separately) and standard outdoor-rated conduit for a complete gate-lock installation. For multi-gate facilities, standardizing on this model simplifies spare-parts inventory and technician familiarity.

We've installed the CX-94S-12LS on dozens of parking-lot and warehouse-perimeter gate projects, and the integrated relay feedback is the feature that keeps drawing specs back to this lock. Most integrators still source magnetic locks and then add a separate magnetic door sensor to report lock status — that's two devices, two failure points, and two wiring paths back to the panel. The Camden consolidates both into one unit with one power supply connection and one status signal. On a 6-gate installation, you're eliminating 6 external switches, 12 wiring runs, and 6 potential corrosion failure modes. We've also appreciated the field-voltage selection — in retrofit scenarios where legacy 12V DC gate operators are still running but the new access control panel is 24V, you don't have to source a separate power supply just for the locks. Set the internal jumpers once, and the lock adapts. The 1200 lb holding force is adequate for most single-leaf and light double-leaf gates; we've never seen a parking-lot or storage-yard gate exceed that pulling load in real deployment. The surface-mount design means you're not milling cutouts or welding frame modifications — that saves significant installation labor compared to embedded strike systems.
Technical Highlights:
- Integrated 1A@30V DC Relay: Eliminates external door-position switch entirely. Direct relay contact to your access control panel input means one wiring path, one device to maintain, one point of failure instead of two. We've seen this reduce serviceability calls by ~30% on high-gate-count sites.
- Dual Voltage (12V / 24V DC field-selectable): Internal jumper selection accommodates both legacy 12V DC gate operators and modern 24V DC access control supplies without requiring inventory SKU splits. On retrofit projects where you're retrofitting 24V panels into 12V infrastructure, this eliminates power-supply replacement overhead.
- 1200 Lb Holding Force: Magnetic attraction — no solenoid plunger to wear out. Continuous duty-rated; holding force does not degrade with repeated unlock cycles. Adequate for parking-lot and storage-yard single-leaf gates; double-leaf gates above 36″ width may require secondary mechanical locks.
- Compact Surface-Mount Footprint: 2.5″ × 8″ × 1.625″ fits standard gate-frame latch pockets without structural drilling. Conduit-fitting inlet accepts ½″ or ¾″ NEMA 3R conduit — essential for outdoor installations in rain and freeze-thaw environments.
- Operating Range −15°C to +50°C: Rated temperature span covers North American climates including winter freeze and summer direct sun. Magnetic holding force is temperature-stable; no performance degradation across the operating range.
Deployment Considerations:
- Power supply sizing: Verify your access control power supply has adequate amperage budget before connecting multiple gates. At 500mA @ 12V DC or 250mA @ 24V DC per lock, four gates on 12V will draw 2A — ensure your supply is rated 5A+ for headroom and voltage stability under transient lock-release current spikes.
- Voltage jumper setting is permanent per installation — confirm the correct voltage before final mounting. Field-selectable voltage is set via internal jumpers; reversal after commissioning requires lock removal and bench re-jumper. Document the voltage choice in your site handover notes.
- Outdoor conduit termination is non-negotiable. Do not run exposed field wiring to the lock on perimeter gates; use NEMA 3R (outdoor-rated) conduit with weather-sealed connectors at both lock and panel termination points. Unshielded wiring will corrode within 12–24 months in rain-exposed installations.
- Magnetic armature plate (strike plate) is typically sold separately or included in gate-hardware kits. Confirm armature availability and surface-mount geometry before ordering the lock; some gate-frame designs require custom armature fabrication.
- The lock does not provide mechanical obstruction if power is lost — it will not hold the gate if unpowered. For critical perimeter gates, specify a secondary mechanical latch or solenoid operator that maintains mechanical lock in loss-of-power scenarios (fail-safe vs. fail-secure design per ADA and site risk assessment).
The Camden CX-94S-12LS is the right choice for standard-duty gate-access projects where you want to eliminate external door sensors and simplify field wiring. Parking lots, storage-yard perimeters, warehouse-dock barriers, and tenant-gated access are the sweet-spot use cases. If you're managing a multi-gate facility and want one consistent lock model across different power supplies, the field-voltage selection is a real integration convenience.
