Traffic Loop Detector

Description :

NBLD-100 is a single channel inductive loop detector . The principle
is based on a change in the inductance within the loop which is
caused by the metallic 
components of passing vehicles. The changes are picked up and
evaluated by a microprocessor. Ease of use thanks to automatic
calibration when the operating 
voltage is applied .
Specification:
1) Supply Voltage : 220V, 110V, 24V, 12V AC
2) Supply Voltage : 24V, 12V DC
3) Sensitivity : 11 levels adjustable
4) Operating Temperature : -20°C ~ +65°C
5) Storage Temperature : -40°C ~ +85°C
6) Frequency Range : 20 kHz ~ 170 kHz
7) Reaction Time : 100ms
8) Loop Inductance : Ideal : 80μH to 300μH (incl. conn. wiring) :
Max : 50μH to 500μH
9) Loop connection : < 5m ( optimal )
10) Loop connection wiring: Maximum length 200 meters, twisted
at least 20 
times per meter
11) Dimension : 35x74x85 mm (WxHxL)
12) Net Weight : 300g
Main Function:
  1. To arm card readers and ticket dispensers.
  2. As a barrier/gate/door closing detector.
  3. As a barrier/gate/door opening detector (Free exit).
  4. To generate pulses for counting vehicles.
  5. vehicles in parking and vehicle access control applications.
