The Solution for Tight Spaces: New POSITAPE® Tape Extension Sensors with Integrated Pulley

The new WBR models are now equipped with an integrated pulley mounted directly onto the sensor, which enables a highly flexible pullout angle of the measuring tape. The WBR sensor solution 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, for example position measurement in crane outriggers.

The linear cable extension position sensors of the POSITAPE® series employ a robust stainless steel measuring tape that is coiled onto a precision manufactured drum. The ultra-thin, flexible stainless steel tape (10 millimeters wide, 0.08 millimeters thick) can be guided even on small pulleys and also in 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 degrees, which allows for an installation that can be flexibly adapted to the available mounting set up.

ASM POSITAPE® tape extension sensors utilize a linear and absolute measurement principle without reference operation. Depending on the model, measurement ranges can reach from 1,500 up to 20,000 millimeters (5ft up to 65ft). With a linearity tolerance of ±0.10 percent the sensors can be equipped with analog and digital outputs (SSI- or CANopen,
CAN SAE J1939) achieving a resolution of <0.05 millimeters.
