Tape-extension position sensor

The WB25 Series joins the Positape line of tape-extension position sensors for applications requiring cable pulleys due to space limitations.

The flexible measurement tape is made from stainless steel that is 10-mm wide and 0.08-mm thick. A tape dust wiper cleans the tape each time it is retracted into the housing. The unit’s measurement ranges are 12, 15, 20, and 25 m.

The sensors are available with analog outputs of 0.5 to 10 V, and 0.5 to 4.5 and 4 to 20 mA. Linearity is ±0.05% of full scale. The unit’s angular sensing element is a magnetic encoder, which translates linear motion into an electrical signal.
