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
