Balluff has added a new 160mm stroke length to its BIL range of miniature noncontact displacement sensors.

Balluff has added a new 160mm stroke length to its BIL range of miniature noncontact displacement sensors.

This sensor, along with the current 60mm stroke version, offers noncontact continuous positioning information from a mini-proportioned sensor, only 15 x 15mm profile, all sealed and potted to IP67.

The BIL is ideal for monitoring pneumatic clamp position: just strap it to the outside of the cylinder and it will pick up on the cylinder magnet to give a precise and continuous absolute position.

The BIL's small proportions mean it can also be used for monitoring robot gripper status or linear motion on packaging machinery, and the noncontact technology means it offers an ideal replacement for troublesome potentiometers.

The unique technology inside the magneto-inductive BIL enables its small design and high resolution.

The use of a flat inductive coil and a special ASIC means that the unit can be completely self-contained, needing no separate amplifiers, and sealed to IP67 giving high immunity to vibration and moisture.

Simply supply the BIL with 24V DC in through the M8 connector and it returns a 0-10V and 4-20mA signal proportional to the position of the small magnet position marker.
