Loop detector modules

Accurate vehicle detection for gates, barriers & carparks

Loop detection modules are the essential electronic interface between saw‑cut induction loops in the ground and your access control system. They detect changes in loop inductance when a vehicle passes over and provide relay or logic outputs to trigger gates, boom barriers, roller doors, traffic lights, or counting systems. With models available from leading manufacturers such as Nortech, Procon, AGD, FAAC, Centsys and Elsema, loop detectors deliver dependable performance, flexible configuration, and precise detection for a wide range of applications.

Improve reliability and safety with professional loop detection module supply & installation from trusted brands including Nortech, Procon, AGD, FAAC, Centsys and Elsema. Contact us today to discuss your requirements.

Description

Key Features

  • Accurate detection: Senses vehicles reliably (cars, trucks, forklifts, motorbikes)
  • Configurable outputs: Presence, pulse on entry/exit, or safety hold
  • Multiple voltages: Models available for 12–240 V AC/DC
  • Selectable frequency: Prevents cross‑talk between adjacent loops
  • Adjustable sensitivity: Tune for large or small vehicles
  • Fail‑safe or fail‑secure modes: Choose system behaviour if power is lost
  • Compact DIN‑rail housings: Easy installation into enclosures
  • Indicators: LED status and diagnostics for quick setup

Typical Applications

  • Automatic gates (open on approach, safety hold‑open)
  • Boom barriers and ticket machines
  • Roller doors and shutters (free exit)
  • Carpark entry/exit systems (counting and logging)
  • Traffic signals and control systems
  • Warehouse and loading dock vehicle detection

Benefits of Loop Detectors

  • Reliable – proven technology used worldwide
  • Safe – ensures gates/barriers do not close on vehicles
  • Flexible – configure for different sites and vehicle types
  • Low maintenance – robust electronics with long service life
  • Scalable – multiple loops and detectors can be used on one site

Installation & Integration

  • Power: Wide voltage range models (commonly 12–24 V DC or 110–240 V AC)
  • Outputs: Relay contacts or solid‑state outputs to suit most controllers
  • Mounting: DIN‑rail or panel mount in weatherproof enclosures
  • Integration: Compatible with most gate/door controllers and traffic systems
  • Support: We supply, program, and test detectors to ensure proper loop tuning

FAQs

Will it detect bicycles or pedestrians? No, loop detectors respond to large metal masses like vehicles. Motorbikes can usually be detected with correct loop design and sensitivity.

Do I need one detector per loop? Yes, each loop requires its own channel. Dual‑channel detectors can monitor two loops.

What if I have two loops close together? Detectors with selectable frequency settings prevent interference.

Can detectors be retrofitted to existing gates? Yes, most controllers support loop detector inputs.
