Description:

The OPB610 and OPB620 slotted optical switches consist of an infrared emiƫng diode and an NPN silicon phototransistor with an enhanced low current roll-off to improve contrast ratio and immunity to background irradiance.

The OPB611, OPB621 slotted optical switch consists of an infrared emiƫng 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 operation. The sensitivity to ambient radiation is minimized.

Features:

• Non-contact switching

• Printed circuit board mounting

• Enhanced signal to noise ratio

• PIN photodiode sensor for high speed (OPB611, OPB621)

• Lead centers: 0.275: (OPB61_) / 0.320” (OPB62_)

Applications:

• Non-contact reflective object sensor

• Assembly line automation

• Machine automation

• Machine safety

• End of travel sensor

• Door sensor
