5W 170KHz Double Channel Loop Detector for Vehicle Detection with 220V/110V Input

SINOMATIC Loop detector model LD-600 is designed for vehicle detection applications including access way monitoring, security safeguarding, and vehicle counting. The output signal can be used to control door drive mechanisms, operate barriers, activate card dispensers, and various other automated systems.

The tuning range spans from 50µH to 1000µH, providing wide compatibility with various loops and wiring configurations. Any inductance changes are automatically compensated to ensure reliable operation.

At lower sensitivity settings, the detector accurately identifies vehicles with high chassis or trailers while filtering out cars, bicycles, and other small metallic objects. Sensitivity adjustment is controlled via rotary encoder switches on the panel, with "0" representing low sensitivity and "9" representing high sensitivity. The left switch (A) corresponds to loop A, while the right switch (B) corresponds to loop B.

Defined as the time interval from when metal enters the detection loop until the detector provides output signals.

Upon power activation, the detector automatically calibrates itself. Two red indicator lights illuminate during this process, which typically lasts 2 seconds.

Each channel features two relay outputs. Channel A includes relays A1 and A2, while Channel B includes relays B1 and B2. Relays A1 and B1 provide presence output (activated when metal is detected, deactivated when metal leaves). Relays A2 and B2 offer multifunctional output capabilities, configurable via the three-bit code switch located on the left side of the panel.
