Carlo Gavazzi Wireless Photoelectric Sensor: Battery power avoids buried cables
Carlo Gavazzi long range through-beam photoelectric sensor has a battery-powered emitter, avoiding buried cables. The PD180 can be powered for up to 2.5 years on a pair of 3.6V lithium batteries with user-set 15 or 30 m range.
Buffalo Grove, IL – Carlo Gavazzi’s new long range through-beam photoelectric sensor has a unique battery-powered emitter, the company says. The PD180, designed for industrial doors and gates, has a battery-powered emitter. Installation is quick and easy, without need to bury cables underground or under pavement, or running additional conduit around door openings. The wireless photoelectric sensor can be powered for up to 2.5 years on a pair of 3.6 V lithium batteries. Sensing range can be set by the user at 15 or 30 meters.
The PD180’s receiver can be powered by 12-24 V ac or dc, providing flexibility for any installation. It contains a SPST relay output for normal door or gate operation, and a separate SPST output for low-battery alert. Mechanical alignments are "quite flexible and very simple," company says, thanks to lenses that can be adjusted vertically and horizontally, assuring proper function in even the most challenging installations. Emitter and receiver are made of heavy duty polycarbonate material, suitable for outdoor use.
The 20,000 lux light immunity assures reliable operation – rain or shine. An emitter-mute function allows the sensor to verify proper function before every operating cycle, which contributes to safer door and gate operation.
The PD180 is UL 325 approved, and carries CE and cULus marks, the company announced Oct. 29.
