This makes installation quick and easy, because there is no need to
bury cables or run additional conduit around door openings, says the
vendor. The sensor can be powered for up to 2.5 years on a pair of 3.6V
lithium batteries. Sensing range is user-selectable at 15 or 30 meters.
The sensor’s receiver can be powered by 12-24VAC/DC. The PD180 contains
a SPST relay output for normal door/gate operation, and a separate SPST
output for low-battery alert. Mechanical alignments are said to be
flexible and simple, thanks to lenses that can be adjusted both
vertically and horizontally. An emitter-mute function allows the sensor
to verify proper function before every operating cycle. List price for
a complete set (emitter and receiver) is $138.Carlo Gavazzi Inc.www.gavazzionline.com847.465.6100
