ASM Positape WB17KT series stainless steel tape sensors

ASM has expanded its line of absolute linear position sensors with the Positape WB17KT series of stainless steel tape sensors with measurement ranges of 3500, 6500 and 10,000 mm. This robust sensor features a good service life in a compact housing specifically designed for rugged and harsh environments.

WS sensors use a flexible, stainless steel cable that is wound with only a single layer around a cable drum. This drum is coupled to an angular sensing device such as a potentiometer or encoder for an electrical output signal.

The Positape series replaces the measurement cable with a thin, highly flexible stainless steel band. The WB17KT operates in a similar manner as a tape measure. Advantages of this technology are the ability to have a long measurement range in a relatively compact housing, also the virtually unlimited life of the metal tape and its suitability for the use in confined locations where pulleys must be used.

Features include: rugged design industrial-grade sensor; compact housing; suitable for harsh environments; available with analog 0-10 V, 4-20 mA or 1 kΩ outputs; available with either absolute digital SSI or CAN-Bus outputs; and electrical connection can be made with either an M12 or D8 connector.
