Building from a standard housing with a .125”(3.18 mm) wide slot, the user can specify the mounting tab configuration. The photodiode output provides a lower but more linear output vs. light input when compared to slotted switches with a standard phototransistor output. All housings are an opaque grade of injection molded plastic to minimize the assembly’s sensitivity to ambient radiation, both visible and near-infrared. Discrete shells (exposed on the parallel faces inside the device throat) are IR transmissive plastic for applications where aperture contamination is a concern.

(2) RMA flux is recommended. Duration can be ex tended to 10 sec. max. when flow soldering. (3) All parameters tested using pulse technique. (4) Polar ity is denoted by color of housing top: LED - Clear Sensor - Black PRECAUTIONS: Exposure of the plastic body to chlorinated hydrocarbons and ketones such as thread lock and instant ad hesive products will degrade the plastic body. Cleaning agents methanol and isopropanol are recommended. Spray or wipe do not submerge. Custom electrical, wire and cabling is available.
