OPB620

Sensing and Control Slotted Optical Switch OPB610, OPB611, OPB620, OPB621 Features: Non-contact switching Printed circuit board moun ng Enhanced signal to noise ra o PIN photodiode sensor for high speed (OPB611, OPB621) Lead centers: 0.275: (OPB61_) / 0.320” (OPB62_) DescripƟon: The OPB610 and OPB620 slo ed op cal switches consist of an infrared emi ng diode and an NPN silicon phototransistor with an enhanced low current roll-off to improve contrast ra o and immunity to background irradiance. The OPB611, OPB621 slo ed op cal switch consists of an infrared emi ng diode and a PIN photodiode with a polysulfone housing that is opaque to visible light, but transmissive to infrared. The low tr/tf of the PIN photodiode is ideal for highspeed opera on. The sensi vity to ambient radia on is minimized. Custom electrical, wire and cabling and connectors are available.
