•
Non-contact switch
PCB mount
Wide aperture
Opaque body to minimize sensitivity to ambient light
Description:
OPB804 is a non-contact optical switch with a NPN silicon phototransistor and infrared Light Emitting Diode (LED)
which are mounted on opposite sides of a 0.155” ( 3.94 mm) wide slot.
The device body is a single molded piece opaque plastic that reduces ambient light interference. A wide open
aperture makes it versatile for general applications. LED emissions are near-infrared (850 – 940nm).
Custom electrical, wire and cabling services are available.
Contact your local representative or OPTEK for more information. Compliant to EU RoHS Directive 2002/95/EC.
Applications:
•
Non-contact object sensing
Assembly line automation
Machine automation
Equipment security
Machine safety
DIMENSIONS ARE IN INCHES AND [MILLIMETERS]
TOLERANCES ARE ± .010” [0.25] UNLESS
OTHERWISE STATED

Notes:
(1) Dot indicates # 3 collector lead side.
(2) Feature controlled at body.
(3) Cathode lead may be shorter.
(4) RMA flux recommended. Highly activated water soluble fluxes may attack plastic. Recommend trial to verify application.
(5) Maximum lead soldering temperature .060” [1.6mm] from case for 5 seconds with soldering iron.
(6) Plastic is soluble in chlorinated hydrocarbons and ketones. Methanol or isopropanol are recommended as cleaning agents.
(7) Derate linearly 1.67 mW/°C above 25° C.
(8) All parameters tested using pulse techniques.
(9) Do not connect input diode directly to a voltage source without an external current limiting resistor.
(10) Do not apply reverse voltage to LED. LED will be a 0V in reverse voltage and draw current as if a short.
