Edited by the Engineeringtalk editorial team May 23, 2001

The Series 173 and 174 position transducers , which use a stainless steel cable wound around a stainless steel drum, deliver extended-life, high-reliability linear position measurement

Adding to its line of subminiature position transducers, SpaceAge Control now offers the Series 173 and 174 position transducers.

The products deliver extended-life, high-reliability linear position measurement in a compact size.

Initial applications have included industrial valve control, aircraft flight control surface monitoring, vehicle suspension tracking, and exhaust system thermal expansion verification.

The flexible and space-efficient products use a stainless steel cable wound around a stainless steel drum.

The bearing-mounted drum is mated to a precision potentiometric element that translates linear position information to an electrical signal.

This transducer technology gives high precision, easy installation, and fast calibration.

The products may be quickly mounted using 2-56 screws provided, an optional rotatable mounting base, or custom installation plates.

Series 173 position transducers measure up to 3 inches (76.2 mm) of travel with external dimensions of only 1.28 inches (32.51 mm) diameter by 0.45 inches (11.43 mm) wide.

Series 174 position transducers measure up to 4 inches (101.6 mm) of travel with external dimensions of only 1.71 inches (43.31 mm) diameter by 0.49 inches (12.45 mm) wide.

The products weigh approximately 1 oz.

and are available with right-hand or left-hand cable pull.

Custom configurations are available for unique applications.

The products feature 2K or 5K ohm co-molded conductive plastic potentiometric elements, a -65deg to +125ø C operating temperature range, ñ0.5% linearity, 0.75 watt power rating, and operate for up to 50 million cycles.

Cable tension is user specified and factory set from 2 to 16 oz.
