HOA1887-013

HOA1887 Transmissive Sensor FEATURES  Choice of phototransistor or photodarlington output  Side mount package  Ambient light and dust protective filter  Accurate position sensing  0.010 in.(0.25mm) aperture windows  0.125 in.(3.18 mm) slot width  24.0 in.(610 mm) min. 26 AWG UL 1429 wire leads INFRA-89.TIF DESCRIPTION The HOA1887 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1887- 011, - 012) or photodarlington (HOA1887- 013) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The side mounting package is useful in applications in which the interruptive element is parallel to the mounting plane. Both emitter and detector have a 0.010 in.(0.25 mm) x 0.60 in(1.52 mm) vertical aperture. This feature is ideal for use in applications in which maximum position resolution is desired. OUTLINE DIMENSIONS in inches (mm) Tolerance 3 plc decimals ±0.010(0.25) 2 plc decimals ±0.020(0.51) All devices employ a built- in strain relief for maximum wire attachment strength. The sensor housing contains IR transmissive optical windows. This arrangement provides excellent protection against ambient light while eliminating aperture openings which could be clogged by airborne contaminants. The HOA1887 series contains plastic molded components. For additional component information see SEP8506, SDP8406, and SDP8106. Housing material is polycarbonate. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol. dim_107.CDR Wire color and functions are: Red - IRED Anode Black - IRED Cathode White - Detector Collector 338 h Honeywell reserves the right to make changes in order to improve design and supply the best products possible. HOA1887 Transmissive Sensor ELECTRICAL CHARACTERISTICS PARAMETER SYMBOL MIN TYP MAX UNITS TEST CONDITIONS IR EMITTER DETECTOR COUPLED CHARACTERISTICS ABSOLUTE MAXIMUM RATINGS SCHEMATIC (25¡C Free-Air Temperature unless otherwise noted) Operating Temperature Range Storage Temperature Range Soldering Temperature (5 sec) IR EMITTER Power Dissipation Reverse Voltage Continuous Forward Current DETECTOR Collector-Emitter Voltage Emitter-Collector Voltage Power Dissipation Collector DC Current Honeywell reserves the right to make changes in order to improve design and supply the best products possible. -40¡C to 85¡C -40¡C to 85¡C 240¡C 100 mW [À] 3V 50 mA TRANS. 30 V 5V 100 mW [À] 30 mA DARLINGTON 15 V 5V 100 mW [À] 30 mA h 339 HOA1887 Transmissive Sensor Fig. 1 Fig. 2 IRED Forward Bias Characteristics gra_092.ds4 Pulsed condition TA = 80 °C TA = 25 °C TA = -40 °C 100 Photodarlington 10 Phototransistor 1 0.8 1.0 1.2 1.4 1.6 1.8 10 2.0 100 Fig. 4 Detector Dark Current vs Temperature gra_094.ds4 Dark current - nA Normalized collector current 1000 100 VCE = 30 H=0 10 1 0.1 0.01 0.001 -40 -20 0 20 1000 10000 Load resistance - Ohms Forward voltage - V Fig. 3 gra_096.ds4 1000 Response time - μs Forward current - mA 100 90 80 70 60 50 40 30 20 10 0 Non-Saturated Switching Time vs Load Resistance 40 60 Collector Current vs Ambient Temperature gra_095.ds4 1.2 1.0 0.8 0.6 0.4 0.2 0.0 -50 Free-air temperature - °C -25 0 25 50 75 100 Free-air temperature - °C All Performance Curves Show Typical Values 340 h Honeywell reserves the right to make changes in order to improve design and supply the best products possible. HOA1887 Transmissive Sensor Honeywell reserves the right to make changes in order to improve design and supply the best products possible. h 341
