Said to be the world’s smallest cable-extension transducer, the M150 unit from Celesco (Chats-worth, CA) is approximately the size of a thumbprint. Celesco says its transducer is ideal for use in robotic, biomedical, and automotive testing applications. With an aluminum body measuring just 0.74 by 0.74 by 0.38 inch, the 0.014-inch-diameter nylon-coated stainless steel measuring cable has a range of 1.5 inches. Cable alignment isn’t required for effective use, so the fully retractable measuring cable offers a constant tension and the only -setup needed is attaching it to the object under motion.
The movement of the M150’s internal spring-loaded spool turns the potentiometer, which, when connected to a voltage source, produces a voltage directly proportional to the position of the measuring cable. The expected life is at least 5 million cycles, and the M150 comes with an extra leader cable and an eyelet kit, so users can terminate the measuring cable precisely at the required stroke position. —KD
