Inductive Sensors Single or Dual Loop Detectors Type LD with teach-in • Single or Dual loop detector • Automatically adjustment of detection level • Manual sensitivity for compensations of variations • Easy installation via 11 pin circular plug • Rated operational voltage: 24 VAC/DC, 115 VAC or 230 VAC • Pulse or presence relay output • Output 1A/250 VAC SPDT relay • LED indication for power, relay status and loop fault • Sensitivity boost – only LDP1 • Selectable frequency – prevents cross-talk • Direction logic – only LDP2 Product Description Ordering Key LDP1 SA1B230 Loopdetectorsfor detection of vehicles. The vehicle loop detector is designed to handle all parking, drive-through and access control applications for controlling doors, gates, barri- ers or fences. Type Selection The principleis based ona change in the inductance within the loop when a metal- lic object (vehicles) is passing. The microprocessor evaluates the changes.
