ASM Sensors introduces POSIWIRE sensor WS21 to measure lengths

November 19, 2015 -  ASM Sensors introduces POSIWIRE sensor WS21 to measure lengths at measuring ranges up to 20,000mm.

It is fitted with a non-contact, magnetic multi-turn-sensing encoder, which gives wear free operation and enables very long measuring lengths to be packaged in compact designs. Typical applications include linear measurements for crane booms.

POSIWIRE cable extension sensors use a calibrated measuring cable that is wound in a single layer onto a precision manufactured drum, which transforms the linear movement of the cable into a rotary movement. An angle sensor such as a potentiometer or a digital encoder finally converts it into an electrical output signal.

The POSIWIRE WS21 position sensor is equipped with a magnetic encoder allowing non-contact measurement of angle rotation giving wear-free operation. This results in a high level of operational safety and a long service life. With a protection class of IP67/69K this sensor is able to withstand harsh environmental conditions and ensures highest safety against breakdown in the field. Being highly resistant to water, moisture and condensation the POSIWIRE WS21 sensors are designed to work reliably even in outdoor applications with large fluctuations in temperature. The high resistance against shock (100g/11ms ) and vibration (20g 10Hz-2kHz) increases the functional reliability of the sensor, avoiding expensive machine downtime and repairs.
