Polarised retro-reflective sensors

With a long straight sensing distance of 12m on an 80mm diameter reflector, the PD86 has a simple adjustable horizontal and vertical lens ±4.5° to compensate for uneven mounting surfaces. The sensor is said to be particularly suited to applications where dust and other environmental conditions can influence the sensing distance. The 44 x 86 x 39mm housing is made in either a strong metal (Zamak 5) or a smart grey glass reinforced polycarbonate, avoiding corrosion issues whilst providing a water tight (IP66) and screwless construction. 

For easier mounting, the cable entry has been enlarged and comes with either fixed terminals or a detachable terminal block 6 x 1.5mm2.  The PD86 is said to have immunity against foreign light, SPST, relay output, dipswitch for inverting the relay and for testing the input to a normally high or normally low position, as well as an operating temperature range of -25 to +60°C.

The polarized retro-reflective function filters out any unwanted reflections from shiny objects such as metallic cars, providing a reliable detection source; whilst the dipswitch can be set to work with any door controller, and the two LEDs combined with four selectable settings; Yellow LED for output on and green LED for power, dirty lens and misalignment, makes fault diagnostic simple and fast.  

The PD86 sensor is designed in accordance with the latest standards European and North American regulations for industrial doors and is CE, UL325 and UL508 approved and is compliant with EN12445, EN12453, EN12978 Regulations and ESPE type 2.
