The ULTRA II plug-in style vehicle loop detector is a compact, energy-efficient design with user-friendly features that simplify set-up.

This plug-in style vehicle loop detector 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. In addition, the ULTRA II has options for automatic sensitivity boost (ASB), delay, fail-safe/fail-secure and infinite and normal (5 min.) presence.

The ULTRA II is easy to install and operate. Sensitivity selection is simplified by the ULTRAMETER™ display. Ten sensitivity settings allow for finer adjustment of the detection level, and four frequency selections help to prevent crosstalk in multi-loop applications.
