Slotted Optical Switch
OPB610, OPB611, OPB620, OPB621
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_ )
• Gap: 0.150” (OPB61_ ) / 0.190” (OPB62_ )
Description:
The OPB610 and OPB620 slotted optical switches consist of an infrared emitting 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 emitting diode and a PIN photodiode with a
polysulfone housing that is opaque to visible light, but transmissive to infrared. The low t
r
/t
f
of the PIN photodiode
is ideal for high-speed operation. The sensitivity to ambient radiation is minimized.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
Applications:
• Non-contact reflective object sensor
• Assembly line automation
• Machine automation
• Machine safety
• End of travel sensor
• Door sensor
