DESCRIPTION
The OPB861T series of switches is designed to allow the user maximum flexibility in applications. Each switch consists of an infrared emitting diode facing an NPN phototransistor across a .125" (3.18 mm) gap. A unique housing design provides a smooth external surface to prevent dust built-up while molded itnernal apertures give precise positioning and also provide protection from ambient light interference.

FEATURES
■ Fully enclosed design allow dust and ambient light protection.
■ Lead spacing at .320".
■ .050" and .010" aperture options.
■ PCB mountable.
