A sensor manufacturer has expanded its product line of tape-extension position sensors, POSITAPE with the introduction of the WB25 series. The family was developed for applications that require the use of cable pulleys due space limitations. The measurement ranges of the WB25 series are 12m, 15m, 20m and 25m all in compact housings.
The flexible measurement tape is constructed out of a high-tech stainless steel material that is 10-mm wide with only a 0.08-mm thickness. Due to its very smooth surface, the risk of icing is reduced. An integral tape dust wiper automatically cleans the tape each time that it is being retracted into the housing.
The WB25 series has a standard IP64 enclosure rating with an option for an IP67 rating and is available with the typical analog outputs: 0.5 to 10V, 0.5 to 4.5 and 4 to 20 mA. For the digital output versions, CANopen, CAN SAE J1939 and SSI protocols are available. The linearity of WB25 series sensor is ±0.05% of full scale.
The angular sensing element consists of a magnetic encoder which translates the linear motion into an electrical signal. This highly reliable magnetic encoder is very shock and vibration resistant which allows it to function in demanding environmental conditions. The space saving stainless tape design provides a small housing foot print with long measurement ranges.
