The HOA1889 Series consists of two infrared emitting diodes facing
two NPN silicon phototransistors (HOA1889-011) or two photodarlington
transistors (HOA1889-013) encased in a black thermoplastic housing.
Detector switching takes place whenever an opaque object passes
through the slot between the the emitter and the detector. The dual
channels allow both the speed and the direction of the interrupter to be
sensed. Emitters and detectors have a 0,5 mm (0.020 in.) vertical
aperture. This feature is ideal for use in applications in which high
position resolution is desired.
The sensor housing is an opaque thermoplastic with aperture
openings for use in applications in which maximum rejection of ambient
light is important and maximum position resolution is desired. The
HOA1889 Series contains plastic molded components. For additional
component information see SEP8506, SDP8406, and SDP8106.
Housing material is Valox
. Housings are soluble in chlorinated
hydrocarbons and ketones. Recommended cleaning agents are
methanol and isopropanol.
Valox is a registered trademark of General Electric Company.
