Description:
The OPB817Z slotted switch consists of an infrared emitting diode and a NPN silicon phototransistor mounted in
an opaque housing with clear windows for dust protection. Switching of the phototransistor occurs whenever an
opaque object passes through the slot.
The OPB817Z has an 0.86" (21.844 mm) deep slot allowing for a longer reach of the optical center line from the
mounting plane. The phototransistor internal apertures are 0.10" x 0.06" (0.25 mm x 1.52 mm) on the sensor side
("S") and 0.05" x 0.06" (1.27 mm x 1.52 mm) on the emitter side ("E").
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
Applications:
Non-contact object sensing
Assembly line automation
Machine automation
Equipment security
Machine safety

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/C above 25 C.
(3) All parameters were tested using pulse techniques.
(4) Lead spacing of 0.220" (5.59 mm) or 0.320" (8.13 mm) is available. Leads are 0.20" square (5.08 mm) and 0.425" long (10.80
mm), which is the minimum.
(5) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and
ketones. Spray and wipe; do not submerge.
(6) Polarity is denoted by color of housing top: LED (gray or clear), sensor (black).
(7) Clear dust protection.
