Vishay TSSP-HA plastic housing for reflective presence and proximity sensors

Vishay Intertechnology has introduced a miniature plastic housing for the rapid prototyping of reflective presence and proximity sensors. The housing is designed to provide optical isolation between a 3 mm (T1) infrared (IR) emitter and any of Vishay’s TSSP-type presence or proximity sensors.

For reflective sensor applications such as automatic hand dryers, automatic towel dispensers, toys and vending machines, optical isolation between the emitter and sensor is a necessity. With their high sensitivity, Vishay Semiconductors TSSP sensors can be inadvertently activated by even minimal light leakage. To prevent this, designers have traditionally had to spend time constructing their own mechanical housings and light isolation.

To speed up prototyping and enable small production runs, Vishay’s TSSP-HA plastic housing provides designers with the optical isolation they require while aligning the emitter and sensor leads on standard breadboard grids. The cavity on each side of the holder is designed with a recessed top edge for cover pieces, simplifying the task of designing an aperture for the sensor or aiming tube for the emitter, if required. Capable of withstanding wave soldering temperatures on the opposite side of the PCB, the product is RoHS compliant, halogen free and Vishay Green.
