Overview
The EMX D-TEK-24V loop detector is a 24VAC-powered inductive vehicle sensor designed for access control and gate/door operator systems. This detector identifies the presence of ferrous metal objects by monitoring changes in loop inductance, making it ideal for triggering automated gate and door operations. Built to U.S. manufacturing standards, the D-TEK-24V delivers reliable object detection with integrated surge protection.
Key Features
- 24VAC power input with integrated surge protection on all inputs and outputs
- Inductive loop technology for ferrous metal detection
- Fail-safe and fail-secure operation modes
- Standard 11-pin harness compatibility for universal installation
- Easy tuning and configuration for gate/door applications
- U.S. manufactured construction
Technical Specifications
The EMX D-TEK-24V features a straightforward power and relay architecture suitable for standalone or integrated control systems. Operating on 24VAC, this detector requires minimal auxiliary power while delivering consistent presence detection through standard inductive loop wiring (0.5–5 ohm loop resistance nominal).
- Input Power: 24VAC
- Current Draw: Typical 17–19 mA at 24VAC
- Output: 2 Form-C relays (SPDT)
- Loop Connection: Standard 2-wire (0.5–5 ohm loop resistance)
- Operating Modes: Fail-safe and fail-secure
- Sensitivity Settings: 10 adjustable levels
- Mounting: 11-pin plug or panel-mount enclosure
- Operating Temperature: 0–50°C (32–122°F)
- Housing: Steel RF-shielded enclosure
- Certifications: UL listed for gate operators
Typical Applications
- Gate operators (swing, slide, overhead)
- Door operators (residential and commercial)
- Traffic control and vehicle detection
- Parking lot and driveway automation
- Access control systems requiring vehicle presence
- Entrance/exit detection for gates and barriers
Compatibility & Replacements
Compatible With
- Standard 11-pin relay sockets and harnesses
- 24VAC gate and door operator power supplies

- Most commercial-grade gate operator controllers
Replaces / Drop-In Replacement For
The D-TEK-24V is a direct replacement for earlier EMX 24VAC-specific loop detector models. Note: EMX has transitioned newer installations to the MVP D-TEK multi-voltage detector (12VDC–240VAC), which offers greater voltage flexibility. Verify your application power requirements before ordering.
Works With
- Gate opener control panels with 24VAC auxiliary power
- Inductive loop conditioner and isolation transformer designs
- Access control relay logic (SPDT 2-relay output)
- Surge-protected control circuits and power distribution
