The Honeywell HOA088X/089X series transmissive sensors are designed for reliable position sensing in a variety of industrial applications. These sensors consist of an infrared emitting diode paired with an NPN silicon phototransistor, housed in a thermoplastic enclosure. Users can customize the sensor with different mounting configurations, detector aperture sizes, and housing materials to optimize performance. The HOA088X models feature IR transmissive housings, suitable for environments where aperture blockage is a concern, while the HOA089X models utilize opaque housings for maximum ambient light rejection. These sensors are ideal for applications requiring precise position resolution and reliable detection of opaque objects.
