The LD-102 loop detector is an intelligent, extremely flexible and very affordable product.
The LD-102 is designed to accommodate numerous applications, can be adjusted intelligently to any environments and virtually eliminating false detection.
On the front panel, the four selectable loop frequencies (20~80 KHz) can completely eliminate any crosstalk.
If intermittence happen or failed loops get self-healed, the detector will resume to normal operation without manually reset the detector.
Self-tuning & complete environmental tracking.
Two-color LED status indicator for Detect, Power, and Loop Fault indication.

The digital technology of the loop detector enables the equipment to sense a change in the inductance of the loop as soon as it detects the metal object in its path.
The inductive loop which detects the object is made of insulated electrical wire (32/020; 32 Strand, 2mm diameter) and is arranged either as a square or rectangle shape.
Compact Size: the compact and well engineered housing Combines all of the industry requirements regarding features and functionality and allows this detector to be Incorporated into any or existing traffic detection system.
Diagnostic Capabilities: Comprehensive diagnostics Capabilities allow for accurate diagnosis of loop and Installation problems.
Selectable Presence Time: The output of the presence Relay can be selected to limit a detect output to a fixed time(time>30 minutes)while a vehicle remains on the loop Loop Frequency Indication: Interference between adjacent loop/detectors can be determined by an integral indication, and eliminated by changing the frequency setting.
Two separate output relays:
Presence Relay A is presence output. Can be extended for 0,2,5,8,10,15,20 or 30 seconds, programmable with external 10 way DIP switches.
Pulse Relay B, programmable with external 10 way DIP switches, provides presence, pulse on entry, pulse on exit, or failed output.
