The SPX1189-002 is a through beam Infrared Emitter Module work together as a pair. The IRED (infrared emitting diode), SPX1189-002 and the detector (phototransistor) SPX1189-003, are enclosed in black thermoplastic housings. The 12-inch (305mm) long 26AWG lead wires are terminated with Molex 03-06-2032 connectors. The detector's NPN output switches whenever an opaque object blocks the beam path. The buffer logic provides logic high when the optical path is clear and a logic low when the optical path is interrupted. The internal current limiting resistor in the emitter module eliminates the need for an external interface circuit. The detector contains an IR transparent filter, minimizing the effect of visible ambient light. The SPX1189-003 series through beam module is tested for coupled characteristics at a gap of 4-inch (101.6mm). This gap can easily be changed for applications with other spacing requirements.
