CARLO GAVAZZI LDD and LDP Loop Detectors designed for single and dual loops.

CARLO GAVAZZI launched its LDD and LDP series of Loop Detectors for either single or dual loops, available in either plug-in or DIN rail mount housings. Used for traffic management, the LDD (DIN Rail) and LDP (Plug) series are equipped with automatic loop frequency tuning and sensitivity tuning. The component’s automatic sensitivity boost (ASB) ensures detection of high bed vehicles such as trucks or busses. Other features include 20µH to 1000µH loop input inductance; fail safe and fail secure functions; selectable output operation (pulse or presence); and automatic or manual loop frequency tuning. The detectors also integrate multicolor diagnostics LEDs and two SPDT relay outputs.
