TE Connectivity M150 potentiometer is the world’s smallest string pot

The M150 string potentiometer by TE Connectivity

Among the many international manufacturers whose test and measurement solutions are available in Canada through Durham Instruments is TE Connectivity. A unique item from this company’s portfolio is the M150 string (draw wire) potentiometer: the world’s smallest string pot. This device occupies space of 0.74 by 0.74 by 0.38 of an inch.

Smaller than a typical thumbprint, the M150 is engineered for space-critical applications and offers a full stroke measurement range of 1½ inches.

Easy installation and trouble-free operation

This string potentiometer has been designed for throttle position, crash-test instrumentation, and many other specific test applications in the aerospace and automotive industries. Durham Instruments recommends the M150 for use in many other industries too, such as general manufacturing, automation, food processing, forestry, education, the medical field, the military, mining, packaging, power generation, alternative energy, transportation, and research and development.

The M150 is constructed entirely of anodized aluminum and has a high-cycle conductive plastic potentiometer as a sensor, which results in easy installation and trouble-free operation. This plastic potentiometer is the heart of this miniature string pot, as it delivers a high-linearity voltage position feedback signal. The rugged aluminum construction ensures that the M150 delivers reliable performance and offers installation that is fast, simple, and completely hassle-free.

The TE Connectivity M150 string pot weighs only 14 grams at the most and offers a maximum measuring cable acceleration of 39 grams. Other important features and benefits of this ultra-miniature unit:

• voltage divider output;
• accuracy of plus or minus one per cent full stroke;
• essentially infinite resolution;
• device cycle life of five million cycles; and
• measuring cable, 0.14 of an inch in diameter and made of nylon-coated stainless steel.

Durham Instruments carries many other world-class solutions by TE Connectivity. Examples include the GCD gauge head, a wide variety of rate sensors, the Model 142A inline strain gauge amplifier, the Model 4020 and 4030 accelerometers, and many others.
