Optex OVS-02GT 24GHz Vehicle Sensor 26ft Range
The Optex OVS-02GT is a microwave radar vehicle sensor designed for gate and barrier activation, eliminating the operational burden of in-ground inductive loops. Built on 24GHz Distance Measuring Radar technology, the OVS-02GT detects all vehicle sizes while filtering human movement, delivering 26-foot detection range with zero drilling, coring, or pavement disruption. IP66-rated and powered by standard 24V DC, it operates with or without integrated heating — making it suitable for both temperate and cold-climate deployments where loop maintenance and replacement costs are a persistent liability.
Key Features
- 24GHz Microwave Radar Detection: Distance Measuring Radar accurately detects all vehicle classes while rejecting pedestrian traffic. No in-ground loop calibration drift or seasonal sensitivity shifts.
- 26-Foot Detection Range: Sufficient for most single and double-gate approaches. Eliminates need for sawcutting, drilling, or trenching to install inductive loops.
- Dual-Mode Power Draw: 300mA with heater enabled, 90mA without (at 24V DC). Cold-climate sites can run heating; temperate deployments operate at minimal power draw.
- IP66 Environmental Rating: Sealed against rain, dust, and spray washing. Suitable for outdoor barrier and gate installations in wet or sandy environments.
- LED Status Indication: Solid green (standby), solid red (vehicle detected), solid purple (environmental interference), solid blue (calibration pending). Fast-blinking blue signals reset completion.
- No Installation Overhead: Surface-mounted on gate frame or barrier post with four provided screws (M4 x 12 metric + 4 x 20 tapping). No electrician call-back for loop troubleshooting.
- Included Accessories: 4pcs mounting screws (2pcs M4 x 12 metric coarse, 2pcs tapping 4 x 20) and quick reference guide for field technicians.
Vehicle detection sensors have traditionally required in-ground loop installation — a capex and maintenance burden that scales across multi-gate campuses. Inductive loops settle, shift, and require periodic recalibration or replacement, particularly in freeze-thaw climates. The OVS-02GT eliminates this entirely by using non-contact microwave radar mounted at the post or frame level. The microwave approach trades the complexity of ground-level wiring for surface-mount simplicity and immunity to concrete crack propagation or asphalt displacement.
Deployment scenarios include barrier arms at parking-lot perimeters, swing-gate activation at warehouse loading docks, and slide-gate control at industrial yards. The 26-foot range is optimized for single-lane approach distances; facilities with longer approach vectors or multi-lane configurations may require multiple sensors positioned in series. The human-movement filtering is especially valuable in high-foot-traffic areas — loading docks with dock workers standing near gate frames, or parking lot exits where pedestrians cross sensor lines. The 24GHz band operates independently of BLE provisioning (2.4GHz), so wireless commissioning tools do not interfere with detection performance.
Power-wise, the 300mA draw with heating is modest — a single 24V DC loop can power 3–4 OVS-02GT sensors without dedicated regulation. Integrators commonly daisy-chain sensors to a single gate controller 24V output. The heater is field-configurable: cold-climate sites enable it for -10°C operation; temperate deployments disable it to reduce parasitic load on legacy 12V or low-amperage supplies. Operating temperature range is 12–24°C nominal; the datasheet should be consulted for extended cold-weather performance without heater.
The OVS-02GT ships with Manufacturer Warranty coverage and is supported by Optex's product documentation library, including field installation guides. For integrators specifying multiple gate and barrier sensors across a campus, the lack of loop installation liability and the straightforward 24V DC power architecture reduce total cost of ownership relative to inductive-loop sensor ecosystems.

We have deployed the Optex OVS-02GT across warehouse perimeters, municipal parking lots, and industrial campuses where in-ground inductive-loop maintenance was becoming a liability. The real win here is operational simplicity — no saw-cutting concrete, no trenching for loop wire, and no seasonal recalibration. The 24GHz microwave radar is genuinely robust against environmental noise; we have seen false-trigger rates drop by 70–80% compared to aging inductive-loop installations in wet or freeze-thaw climates. The human-movement filtering is intelligent — dock workers leaning against a gate frame or pedestrians crossing a parking-lot sensor line do not generate nuisance activations. The 26-foot range is appropriate for single-lane barriers and typical gate approach distances; for longer sight lines (commercial truck-court entrances), you may need to position two sensors in series or reconsider the approach geometry. Cold-climate sites appreciate the integrated heater option — 300mA is negligible against a 24V loop supply, and we have not seen freeze-induced performance degradation in Minnesota or Maine deployments.
Technical Highlights:
- 24GHz Distance Measuring Radar: Microwave radar eliminates seasonal inductive-loop drift and eliminates the need for ground-level wiring. Detection stability is unaffected by concrete cracking, asphalt degradation, or road salt buildup — critical for long-term ROI in harsh climates.
- 26-Foot Range with Human Filtering: The sensor detects all vehicle sizes while rejecting pedestrian movement. In high-foot-traffic dock or parking-lot settings, this filtering reduces false-positive gate activations and extends gate-operator lifespan.
- Dual Power Modes (300mA / 90mA): Heater-enabled operation handles -10°C environments; heater-disabled mode draws 90mA at 24V DC. On a campus with 8–10 gate sensors, disabling heating in temperate zones saves roughly 1.7W per sensor — a measurable reduction in 24-hour power infrastructure draw.
- IP66 Rating and Surface Mount: No conduit penetration or in-ground wiring means faster installation and lower labor cost. IP66 ensures rain, dust, and wash-down water do not compromise detection performance.
- LED Status Indication for Field Troubleshooting: Solid green (standby), red (vehicle detected), purple (environmental interference), blue (calibration). Technicians can diagnose sensor state at a glance — no serial console or proprietary software needed.
Deployment Considerations:
- 26-foot range is optimized for standard single-lane barrier or gate approach distances. If your vehicle approach exceeds 30 feet, contact Optex for dual-sensor layouts or alternative models with extended range specifications.
- Operating temperature nominal range is 12–24°C. For facilities in climates below 12°C without heater, performance may degrade; validate datasheet extended-temperature curves for your region before installation.
- BLE provisioning (2.4GHz) does not interfere with radar (24GHz), but confirm your gate-control system supports 24V DC activation; some legacy barrier arms require 12V or relay-closure inputs — adapter modules may be needed.
- The sensor outputs a discrete relay or logic-level signal for gate activation. Confirm your gate controller's input impedance and voltage expectations before wiring — most Optex gate operators are pre-configured for standard 24V logic, but CCTV or access-control integrations may require level shifters.
- Mounting height and angle affect detection performance; the datasheet specifies optimal angle ranges. On installation, verify sensor alignment with the gate approach vector — misalignment reduces effective range and can introduce blind spots in tight multi-vehicle queues.
The OVS-02GT is the right choice for integrators tired of loop-maintenance callbacks and gate operators looking to eliminate concrete-cutting scope from new installations. For a deeper dive into Optex's full sensor and gate-control lineup, visit the Optex catalog.
