Overview
The EMX D-TEK-24V DC loop detector is a voltage-specific inductive vehicle detection sensor engineered for gate operators, garage door systems, and access control applications. Operating at 24VDC, this unit provides full loop diagnostics, frequency counter functionality, and configurable relay outputs. EMX loop detectors are designed to work with preformed inductive loops or field-wound installations to reliably detect vehicle presence.
Key Features
- 24VDC input power supply
- Loop diagnostics with frequency counter for troubleshooting
- 10 sensitivity settings for loop optimization
- Configurable fail-safe and fail-secure modes
- Two relay outputs for pulse and constant presence detection
- Surge protection and lightning immunity
- Loop isolation transformer and frequency conditioner
- Adjustable delay and extend detection features

Compatibility & Replacements
Compatible With
- Standard 24VDC gate and door operator power supplies
- Preformed inductive vehicle detection loops (0.5–5 ohm impedance)
- Field-wound and burial probe loop installations
- Generic gate access control systems with 24VDC auxiliary power
- EMX wiring harnesses (e.g., EMX-HAR-11)
Replaces / Drop-In Replacement For
Note: EMX has discontinued voltage-specific D-TEK models and replaced them with the MVP-D-TEK (Multi-Voltage 12VDC–240VAC). The D-TEK-24V is a legacy product. For new installations and replacements, EMX recommends the MVP-D-TEK universal-voltage detector. If you require a direct 24VDC replacement for legacy systems, verify compatibility with your system integrator before ordering.
Works With
- EMX preformed loop systems and loop conditioners
- Standard 2-wire inductive loop wiring
- Relay-based control logic modules and PLC interfaces
- Any 24VDC gate or door operator system with 10–50 mA auxiliary power capacity
