The HOA6299 Series through beam infrared sensor modules operate

as a pair. The infrared emitting diode, HOA6299-002, and the detector,

HOA6299-003, are encased in black thermoplastic housings. Both the

emitter and detector modules employ 24 AWG wire leads which are

terminated with a Panduit CE156F24-2 connector for the HOA6299-002,

and a Panduit CE156F24-3 connector for the HOA6299-003.

The detector’s NPN output switches whenever an opaque object

blocks the beam path. The buffer logic provides a logic high when the

optical path is clear, and a logic low when the optical path is blocked.

The internal current limiting resistor in the emitter module eliminates the

need for an external interface circuit. The HOA6299 series employs an

IR transmissive housing which features smooth optical faces without

external aperture openings; this feature is desirable when aperture

blockage from airborne contaminants is a possibility.

The HOA6299 Series through beam modules are tested to ensure

operation at minimum separation of (63,5 mm) 2.5 in. This gap can

easily be changed for applications with other spacing requirements.

Housing material is IR transmissive polysulfone. Housings are soluble

in chlorinated hydrocarbons and ketones. Recommended cleaning

agents are methanol and isopropanol.
