Inductive Loop Detectors

3-Series detectors offer proven reliability with front-panel DIP switch configuration in boxed housings, suitable for straightforward applications. 8-Series detectors provide advanced features including remote WiFi configuration via smartphone, slimline DIN-rail mounting, and enhanced diagnostics. The 8-Series includes Automatic Frequency Selection that automatically optimises operating frequency, power fail memory to retain vehicle presence during outages, and the ability to link multiple detectors. 8-Series models come with comprehensive five-year warranties and simplified stock management with only two power variants.

Automatic Frequency Selection examines the detector's electromagnetic environment and automatically sets the optimal operating frequency to minimise interference from adjacent loops or electrical noise. This eliminates manual frequency adjustment during installation, significantly reducing setup time and technical expertise required. In multi-lane installations where multiple detectors operate proximity, AFS ensures each detector operates on interference-free channels. This feature particularly benefits complex parking facilities and access control sites where electromagnetic interference could compromise detection reliability without causing installer headaches.

Parking detectors excel in barrier control, gate automation, safety loops, and vehicle counting where presence detection is primary. They monitor whether vehicles occupy detection zones, triggering barriers to remain open or providing anti-crush safety. Traffic detectors add speed measurement, vehicle length classification, and headway timing capabilities essential for traffic management applications. Use traffic detectors for speed enforcement zones, vehicle classification systems, traffic flow monitoring, and applications requiring differentiation between vehicle types or measuring distances between successive vehicles through detection zones.

Power fail memory on 8-Series detectors retains vehicle presence information during power interruptions, immediately recognising occupied loops when power restores. This prevents barriers or bollards from activating whilst vehicles occupy detection zones, avoiding potentially dangerous collisions or equipment damage. The detector can also determine if vehicles entered detection zones during power outages, ensuring accurate system state upon restoration. This critical safety feature proves essential for rising bollards, barrier systems, and any application where unexpected activation during power restoration could cause vehicle damage or safety hazards.

Yes, modern loop detectors incorporate frequency management to prevent interference. 8-Series detectors feature Enhanced Automatic Frequency Selection with 32 available channels, automatically coordinating with nearby detectors to select interference-free frequencies. Up to four synchronised dual-channel 8-Series detectors can be linked together, sharing frequency information to optimise multi-lane installations. The 3-Series provides manual frequency indication through front-panel LEDs, allowing installers to select appropriate frequencies. This multi-channel operation enables reliable detection in complex sites with numerous detection zones operating simultaneously without crosstalk or false triggering.
