Tracking cars traffic in and out double channel inductive 10 grade sensitivity vehicle loop detector
LD-600 is used for wherever vehicles have to be detected, for example for monitoring and safe-guarding
access ways or for counting vehicles. The output signal can be used for controlling door drive mechanisms,
operating barriers, activating card dispensers etc.

Double loop detector LD-600 panel
The tuning range is from 50µH to 1000µH, and such wide tuning range ensures low requirements for the loop and
wiring. Any inductance changes will feedback to the compensation circuit in detector to ensure normal work.
b. Adjustable sensitivity
When in low sensitivity, the detector will detect vehicles with high chassis or trailers correctly except cars, bicycles
and other small metals. The sensitivity adjust button is the rotary encoder switch on the panel, “0” with low
sensitivity and “9” with high sensitivity. The A switch on left is corresponding to loop A, while B on right is
corresponding to loop B.
c. Reaction time
Its definition is the time starting from the metal enters into the loop and ending when the detector gives indication
d. Frequency adjustment
When power on, the detector can calibrate itself automatically and the two red lights are on which will
continue for 2s.
e. Output mode of relay
Every channel has two relay outputs in our detectors. There are two relays A1 and A2 with channel A. And there
are two relays B1 and B2 with channel B. Relay A1 and B1 are existing output (on when metals on the loop and off
when metals leaving). Relay A2 and B2 are multifunctional output set by the three bit code switch on the left of the panel.
Operate as follows:
