Camden CX-91S-12TDS-BK Magnetic Lock with Adjustable Timer

Overview

The CX-91S-12TDS-BK is a 1,200 lb capacity surface-mount magnetic lock built for single-door access control installations where you need electronic strike control without mechanical complexity. The integrated TDS (timer/door sensor) module provides adjustable unlock duration, a door status switch, and a relay output — all on one compact strike body. Field-selectable 12/24 VDC operation means you can wire to whatever power your access control panel supplies without additional converters. Vandal-resistant construction and lifetime warranty coverage make this the standard choice for institutional and commercial deployments running high-traffic corridors, secured entries, or emergency egress doors.

Compatibility

The CX-91S-12TDS-BK integrates with any access control system capable of driving a 24VDC solenoid strike — including conventional hardwired panels, IP-based door controllers, and cloud-managed platforms. Surface-mount form factor fits standard single-door aluminum or steel frames without frame modification. The included mounting template guides installation on new construction or retrofit. Door status switch output (0.5A @ 28V AC/DC) pairs with monitor inputs on most commercial access control panels; bond sensor output (2A @ 24VDC) can drive auxiliary relays or notification circuits. Adjustable timer dial on the strike body itself — no software configuration needed — makes it field-serviceable for variable unlock dwell times (typically 0.5–10 seconds depending on application).

Installation Notes

Draws 240mA @ 24VDC (standard operating load) or 480mA @ 12VDC — confirm your power supply and access control panel outputs have sufficient amperage budget. Surface mounting requires four screws into the frame head; spacer kits are available for recessed installations or non-standard frame depths. On-board MOV surge protection shields against power transients common in panel installations. Do not exceed 28V AC/DC on the door status switch contact or 24VDC bond sensor output — respect these ratings to avoid coil damage. Environmental rating suitable for indoor lobbies, controlled institutional spaces — not rated for direct weather exposure without a separate protective housing.
