Tiny plastic housing speeds prototype development

Vishay Intertechnology has broadened its optoelectronics portfolio with the introduction of a miniature plastic housing for the rapid prototyping of reflective presence and proximity sensors. The housing is uniquely designed to provide optical isolation between a 3mm (T1) infrared 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 an absolute necessity. With their extremely high sensitivity, Vishay Semiconductors TSSP sensors can be inadvertently activated by even very small light leakage. To prevent this, designers have traditionally had to spend valuable 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. In addition, 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 TSSP-HA is RoHS-compliant, halogen-free, and Vishay Green. Samples and production quantities of the TSSP-HA are available now, with lead times of five weeks.
