ASM POSITAPE WBR tape extension sensor with integrated pulley

ASM has added an extra feature to its POSITAPE tape extension sensor product line. The WBR models are now equipped with an integrated pulley mounted directly onto the sensor, which enables a flexible pullout angle of the measuring tape.

The WBR sensor has been specifically designed for machines with limited space where the tape needs to be deflected. With the integrated pulley the starting angle of the measuring tape is adjustable to a broad range of measurement applications, even in areas that were previously not accessible.

The linear cable extension position sensors of the series employ a robust stainless steel measuring tape that is coiled onto a precision manufactured drum. The ultrathin, flexible, stainless steel tape can be guided even on small pulleys and also in the opposite direction without impairing the service life of the measuring tape. With the pulley mounted directly onto the sensor the pullout angle can be rotated through 90°, which allows for an installation that can be flexibly adapted to the available mounting set-up.

The tape extension sensors utilise a linear and absolute measurement principle without reference operation. Depending on the model, measurement ranges can reach from 1500 up to 20,000 mm. With a linearity tolerance of ±0.10%, the sensors can be equipped with analog and digital outputs achieving a resolution of <0.05 mm.
