Product Overview

The HLC2701-001 is an Infrared Encoder Sensor, designed to sense speed and direction of mechanical motion. Applications include rotary and linear encoders; the device is especially well suited for the encoding function in an optical mouse. The detector is a monolithic IC, consisting of two narrow adjacent photodiodes, amplifiers and Schmitt trigger output stages. The outputs are NPN collectors with internal 10kΩ pull-up resistors to Vcc which can directly drive TTL loads. It incorporates circuitry to compensate the sensitivity for output power versus temperature characteristics of an IRED. The IC is encapsulated in a moulded, unlensed black plastic package which is transmissive to IR energy, yet provides shielding from visible light. The sensing areas of the IC are each 0.008-inch (0.203mm) in width and 0.015-inch (0.381mm) in height with a 0.001-inch (0.0254mm) separation, for centre-to-centre spacing of 0.009-inch (0.203mm) and outside edge to edge distance of 0.017-inch (0.432mm).
  • Side-looking plastic package
  • TTL/LSTTL/CMOS compatible
  • Inverting logic output
  • Linear or rotary encoder applications
  • Resolution to 0.009" (0.229mm)
  • Sensitivity versus temperature compensation
  • Mechanically and spectrally matched to SEP8506 and SEP8706 infrared emitting diodes
