FEATURES
REFLECTIVE SENSORS
HOA1395.
Features: Side-looking plastic package
• Phototransistor output
• Infrared emitter and phototransistor detector in a single package
• Low profile for design flexibility
• Designed for short-distance detection
• Enhanced sensitivity • Unfocused for sensing diffused surfaces
Benefits: Miniature infrared sensor designed to sense reflective objects at short distances. Infrared emitter and phototransistor are mounted side-by-side with an integral barrier to minimize crosstalk.
HOA0149.
Features: Phototransistor output
• Focused for maximum response
• Low-profile housing
• Plastic ABS molded housing
Benefits: An infrared emitter and phototransistor encased side-by-side on converging optical axes. Phototransistor responds to radiation from an infrared transmitter only when a reflective object passes within its field of view.
HOA1180.
Features: Choice of phototransistor or photodarlington output
• Enhanced sensitivity
• Wide operating temperature -55 °C to 100 °C [-67 °F to 212 °F]
• 305 mm [12 in] min. 28 AWG PVC insulated wire leads
• Metal can packaged components
Benefits: Consists of an infrared emitter and phototransistor or photodarlington encased side-by-side on converging axes. Detector responds to radiation from an infrared emitter only when a reflective object passes within its field of view.
HOA1397.
Features: Choice of phototransistor or photodarlington output
• Low profile for design sensitivity
• Unfocused for sensing diffused surfaces
• Plastic-molded components
Benefits: An infrared emitter and phototransistor or photodarlington encased side-by-side on parallel axes. Detector responds to radiation from infrared emitter only when a reflective object passes within its field of view. Potential applications include presence sensing, motion sensing, movement detection, and counting.
HOA1405.
Features: Phototransistor output
• Focused for maximum response
• Ambient light and dust protective filter
• Plastic-molded components
Benefits: An infrared emitter and phototransistor encased side-by-side on converging optical axes. Phototransistor responds to radiation from an infrared emitter only when a reflective object passes within its field of view. Employs an IR transmissive filter to minimize the effects of visible ambient light and to provide a smooth optical face which prevents the accumulation of airborne
