transmissive optoschmitt sensor HOA2001 description features direct ttl interface buffer logic 0.060 in.(1.52 mm) dia. detector aperture 0.120 in.(3.05 mm) slot width 0.050 in.(1.27) offset pin circle detector eads the HOA2001 consists of an infrared emitting diode facing an optoschmitt detector encased in a black thermoplastic housing. the photodetector consists of a photodiode, amplifier, voltage regulator, schmitt trigger and an npn output transistor with 10 k (nominal) pull- up resistor. the buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted. the HOA2001 employs plastic molded components. for additional component information see sep8506 and sdp8600. housing material is polyester. housings are soluble in chlorinated hydrocarbons and ketones. recommended cleaning agents are methanol and isopropanol. dim_062.ds4 infra-45.tif outline dimensions in inches (mm) 3 plc decimals 0.010(0.25) tolerance 2 plc decimals 0.020(0.51) honeywell reserves the right to make changes in order to improve design and supply the best products possible. h 360
