10 / 18 page contaminants in the optical path. Potential applications include presence and motion sensing, position encoding, limit sensing, movement detection, and counting. HOA2498. Features: Choice of phototransistor or photodarlington output • Focused for maximum response • Wide operating temperature -55 °C to 100 °C [-67 °F to 212 °F] • Metal-can packaged components Benefits: An infrared emitter and phototransistor or photodarlington encased side-by-side on optical 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, position encoding, limit sensing, movement detection, and counting. LOW LIGHT REJECTION PHOTOTRANSISTORS SDP8475-201. Features: T-1 plastic package • Low light level immunity • 20° (nominal) acceptance angle • Mechanically and spectrally matched to SEP8505 and SEP8705 infrared emitters Benefits: Phototransistor with internal base-emitter shunt resistance. Transfer molding of this device provides enhanced optical centerline performance. Lead lengths are staggered to provide a simple method of polarity identification. Provides high contrast ratio in reflective applications where unwanted background reflection is a possibility. Potential applications include those which require ambient light rejection, or in transmissive applications where the interrupter media is semi-transparent to infrared energy. SDP8476-201. Features: Side-looking plastic package • Low light level immunity • 50° (nominal) acceptance angle • Mechanically and spectrally matched to SEP8506 and SEP8706 infrared emitters Benefits: Phototransistor with internal base-emitter shunt resistance. Transfer molding of this device provides enhanced optical centerline performance. Lead lengths are staggered to provide a simple method of polarity identification. Provides high contrast ratio in reflective applications where unwanted background reflection is a possibility. Potential applications include those which require ambient light rejection, or in transmissive applications where the interrupter media is semi-transparent to infrared energy. TRANSMISSIVE SENSORS HOA1877. Features: Choice of phototransistor or photodarlington output • Wide operating temperature -55 °C to 100 °C [-67 °F to 212 °F] • 12,7 mm [0.5 in] high optical axis position • 9,52 mm [0.375 in] slot width • Metal can packaged components Benefits: An infrared emitter facing a phototransistor or photodarlington. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. HOA0825. Features: Phototransistor output • Four mounting configurations • 4,2 mm [0.165 in] slot • Plastic-molded components Benefits: An infrared emitter facing a phototransistor or photodarlington. Slot in the housing between emitter and detector provides the means for mechanically interrupting the emitter beam. Phototransistor switching takes place when an opaque object passes through the slot between emitter and detector. HOA086X. Features: Phototransistor output • Often accurate position sensing • Four mounting configurations • 3,18 mm [0.125 in] slot width • Choice of opaque or IR transmissive housings • Options include mounting tab configurations, lead spacing, electro-optical characteristics, detector aperture size, and housing materials • Plastic-molded components Benefits: An IR transmissive polysulfone housing features smooth optical faces without external aperture openings (desirable when aperture blockage from airborne contaminants is a possibility). HOA1879. Features: Phototransistor output • Often accurate position sensing • Choice of detector aperture • 3,18 mm [0.125 in] slot width • Dust protective housing • Plastic-molded components Benefits: Infrared emitter facing a phototransistor. Switching takes place whenever an opaque object passes through the slot between emitter and detector. Employs an IR transmissive housing which features smooth optical faces without external aperture openings (desirable when aperture blockage from airborne contaminants is a possibility). Often ideal where maximum position resolution is desired. HOA1882. Features: Choice of phototransistor or photodarlington output • Compact package size • Dust protective housing • 5,08 mm [0.200 in] slot width • Plastic- molded components Benefits: An infrared emitter facing a phototransistor or photodarlington. Detector switching takes place when an opaque object passes through the slot between emitter and detector. Employs an IR transmissive housing which features smooth optical faces without external aperture openings; desirable when aperture blockage from airborne contaminants is a possibility. HOA088X. Features: Phototransistor output • Four mounting configurations • Often accurate position sensing • 3,18 mm [0.125 in] slot width • 24 in [610 mm] min. 26 AWG UL 1429 leads • Opaque or IR transmissive housings • Options of mounting tab configurations, lead spacing, electro- optical characteristics, & detector aperture size 10 www.honeywell.com/sensing Unless otherwise noted, potential applications include printers and copiers, motion control systems, metering systems, liquid-level sensing, data storage systems, scanning, automated transaction, drop sensors, and other noninvasive medical equipment. |
