Description
The HOA0902 assembly consists of a dual channel IC detector and an IRED
encased in a black thermoplastic housing. The device is typically used with an
interrupter strip or disk (code wheel) to encode the rate and direction of
mechanical motion. Applications include linear and rotary encoders; it is especially
suited for the encoding function in an optical mouse.
The detector is a monolithic IC which consists of two narrow adjacent
photodiodes, amplifiers stages and quadrature logic circuitry which provides two
outputs; (1) a fixed-duration, low level active tachometer (counting) pulse which is
generated whenever the illumination level passes through the sensing threshold,
and (2) a direction output which is set to a logic high or low level dependent on
which of the two channels is illuminated first. The tachometer output is an NPN
collector which is internally connected to Vcc through a 10 kOhm (nominal)
resistor; the direction output is a totem-pole configuration. Both outputs are
capable of directly driving TTL loads. The IC design incorporates circuitry to
compensate the sensitivity for the output power vs. temperature characteristic of
the IRED.
The tachometer pulse is generated at both the increasing and decreasing
illumination thresholds of the sensing channel, resulting in two tach pulses for
each mechanical period of the interrupter. For additional component information
see SEP8506 and HCL2705.
Housing material is polycarbonate. Housings are soluble in chlorinated
hydrocarbons and ketones. Recommended cleaning agents are methanol and
isopropanol.
