Product Description

PD160 – Single Channel Detector

The prestigious PD160 range provides a totally customizable inductive loop solution primarily suited to complex multilane access control. The ease of installation of this product is not only cost effective but a pleasure to operate when determining the optimal parameters with the onboard diagnostics. Nortech is proud to introduce the ultimate parking detector, where sophistication is simplified. 


  • Parking barrier control.
  • Arming control.
  • Motorised gates and doors.
  • Industrial control systems.

Specific Features

  • AFS: The Automatic Frequency Selection allows the ability to automatically select the best frequency setting by minimising the noise and maximise the signal strength.
  • Diagnostic Capabilities: Comprehensive built in diagnostics capabilities allow for accurate diagnosis of loop and installation problems. All the relevant information is displayed on the LCD. The following parameters can be diagnosed: Frequency, Inductance Change, Noise / Interference and Signal Strength. Channel counting information is also available.
  • Completely Configurable: The LCD menu provides customizable functionality in the choice of output variations, frequency and sensitivity settings. Any change in settings is saved in the event of a loss of power, however factory settings can be restored through the menu. A reset of the unit is available from the menu or by a power-cycle.
  • Selectable Permanent Presence: The output of the presence relay can be selected to maintain an output for an indefinite period, eliminating premature barrier / gate / door closure. The default setting is Permanent Presence.
  • Loop Isolation Protection: The loop is isolated and provides protection against lightning and transient damage and allows for operation with single point to ground sensor loops. Added filtering reduces interference from external noise.
  • Loop Frequency Indication: Interference between adjacent loops / detectors can be determined by an integral indication, and eliminated by changing the frequency settings.
  • Automatic Sensitivity Boost (ASB): Facilitates the reliable detection of all vehicle combinations and high-bed vehicles by boosting the sensitivity to maximum after detection of a vehicle.
  • Detect Filter: Provides a turn-on delay, thus allowing selective detection which is often useful for screening out unwanted inputs.
  • PowerFail Memory: In the event of a power failure, the PD160 detector will retain the presence of the vehicle when power is restored. This is most useful in applications where damage to vehicles could occur ( e.g. Rising Bollards).
