MALVERN, Pa. — Dec. 14, 2017 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced new rectilinear and rotational industrial potentiometer membrane displacement sensors designed to deliver reliable performance in harsh environmental conditions. Waterproof and ultraflat, the Vishay MCB UIPMA and UIPMC provide high durability and repeatability for a wide range of applications.
The sensors released today feature an IP66 seal and a very thin active layer with a thickness of 0.5 mm, while a double-sided adhesive layer allows for easy assembly. The devices offer high durability with long life > 3 million cycles (to 10 million and 20 million cycles on request), and operate over a temperature range of -10 °C to +50 °C.
With their durable design, the rectilinear UIPMA and rotational UIPMC are ideal for electrical actuators and cylinder positioning systems for aircraft seats, telecom antennas, syringe pumps and hospital beds, AC valve openings, ship masts, lift-truck steering control, and mining equipment for surveying ground movement. RoHS-compliant, the sensors are available in custom designs.
