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_)
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.

RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum of 20 grams force may be applied to leads when soldering.
Derate linearly 1.33 mW/°C above 25 ° C.
Derate linearly 2.0 mW/°C above 25 ° C.
Plastic body is soluble in chlorinated hydrocarbons and keytones. It is recommended that a trial exposure to flux & cleaning chemicals is performed to ensure sensor is not damaged.
