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
