OPB610 - Slotted Optical Switch

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 s.

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.
