M150, Miniature Draw Wire Displacement Sensor
- Ultra-Miniature String Pot
- Voltage Divider Output 1.5–inch Stroke Range
- Precision High-Cycle Potentiometer
- Designed for Test and Space-Critical Applications
Introducing the M150, acclaimed as the world's smallest stringpot, this ultra-miniature sensor revolutionizes space-critical applications in the aerospace and automotive industries. With dimensions merely larger than a thumbprint (.74 x .74 x .38 inches), the M150 is specifically designed to measure throttle positions, crash test instrumentation, and other applications where space is at a premium. At its core, the M150 features a high-cycle conductive plastic potentiometer, ensuring precision voltage position feedback across a full stroke range of 1.5 inches. This accuracy is further enhanced by its ±1% full stroke precision and essentially infinite resolution, making it an indispensable tool for precision testing.
The sensor's robust anodized aluminum construction guarantees durability and reliability, while its lightweight design (0.5 oz. max.) and easy installation process make it user-friendly. The M150's electrical and environmental specifications, including a NEMA 12, IP 50 enclosure rating and an operating temperature range of -40° to 185°F, underscore its versatility and capability to withstand demanding test conditions. With a potentiometer life of 5 million cycles and a maximum cable acceleration of 39 g, the M150 sets a new standard for compact, high-performance measurement solutions.
