Cable-Extension Position Transducer
M150
Specification Summary:
Introducing the world’s smallest stringpot. The M150 is smaller than a thumbprint and occupies a tiny space of only .74 x .74 x .38 inches. With a full stroke measurement range of 1.5 inches, the M150 has been designed for many aerospace and automotive
space-critical test applications such as throttle position and crash-test instrumentation.
The heart of the M150 is a precision high-cycle conductive
plastic potentiometer that delivers a high-linearity voltage position feedback signal. With its rugged all aluminum construction, the M150 has been engineered for reliability and to provide quick, easy and hassle-free installation.
