WB61

Product catalog summary

Overview: The Positape® WB61 is a tape extension position sensor designed for displacement measurement up to 4,000 mm. It features a robust stainless steel measurement tape and offers various output options including analog, digital SSI, and digital CANopen/SAE J1939. The sensor is equipped with a magnetic absolute encoder and is available in redundant versions.

Specifications: The WB61 sensor offers a measurement range of 1500 to 4000 mm with a resolution of less than 0.05 mm. It supports multiple output types: analog (0.5-10 V, 0.5-4.5 V, 4-20 mA), digital SSI, and CANopen/SAE J1939. The sensor's linearity is ±0.10% f.s. (standard) or ±0.05% f.s. (optional). It is constructed from PBT and stainless steel, with a tape width of 10 mm and thickness of 0.08 mm. The protection class is IP67/IP69 with a mating connector.

Environmental and Mechanical Characteristics: The sensor can operate in temperatures ranging from -40 to +85°C and withstands shocks up to 100 g/11 ms and vibrations of 20 g from 10 Hz to 2 kHz. It complies with EMC standard DIN EN 61326-1:2013.

Output Options:

Analog Output: Available in standard, programmable, and redundant versions. The programmable version allows for customer-defined start and end values using a binary signal.
Digital Output SSI: Features a synchronous serial interface with a clock frequency of 100-500 kHz and Gray-Code data format.
Digital Output CANopen/SAE J1939: Supports CANopen CiA 301 V 4.02 and SAE J1939 communication profiles with adjustable transmission rates and node IDs.

Connection and Wiring: The sensor uses M12 connectors with 5 or 8 pins depending on the output type. Detailed wiring instructions are provided for each output configuration.
