The OPB800W series, remote mounted [24” (610 mm) 26 AWG wire] wide gap switch provides the flexibility of a custom device from a standard product line. Building from a standard housing that utilizes a 0.375” (9.5 mm) wide slot, a user can specify the electrical output parameters, discrete shell material and the aperture width. Housings are made from an opaque grade of injection-molded plastic that minimizes the assembly’s sensitivity to visible and near-infrared ambient radiation. Discrete shells, which are exposed on parallel faces inside the device throat, are made of IR transmissive plastic (for applications where aperture contamination may occur) or of opaque plastic with aperture openings (for maximum protection against ambient light). Custom electrical, wire and cabling and connectors are available. 0.375”/0.350” slot width; 0.05 IC(ON) (mA); 20 typ. And 50 max IF (mA); 30 VCE; 0.01” emitter and sensor aperature; 24”/26 AWG wire lead length.
