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.
