The ULTRA-PLG vehicle loop detector combines small size with full-featured functionality in a plug-in module.
This detector features DETECT-ON-STOP™ or (DOS) technology, which allows detection only when a vehicle has come to a complete stop on the loop. This exclusive feature is unique to EMX and is a major advantage if you want to ignore cross traffic in tight spaces.
The ULT-PLG provides a solid-state output indicating vehicle presence. The second output can be used for presence, loop fault or pulse on entry/pulse on exit. Our latest vehicle detector provides options for automatic sensitivity boost (ASB), delay, fail-safe/fail-secure and infinite and normal (5 min.) presence.
This detector is easy to install and operate. Sensitivity selection is simplified by the ULTRAMETER™. Ten sensitivity settings allow for finer adjustment of the detection level. The four frequency selections help to prevent crosstalk in multi-loop applications.
The ULT-PLG is compatible with a wide variety of gate operators. Please see the spec sheet for a detailed list.
