Miniature Draw-Wire Sensors

Draw-wire / string-pot / cable-pull encoders are used for linear positioning, and with their small size, the MDW fits any application.

From now on, POSITAL's new MAGNETOCODE (MCD) encoders are also available as cost-efficient models featuring an integrated draw wire adapter. The units serve to measure linear distances in machine building, construction, or instrument engineering applications and can also be employed in medical engineering. The cable pull adapter provides a 1.2 meter or 2.1 meter measuring range and is encased in a plastic housing measuring 56 x 46 x 21 mm. Drum and spring are flanged directly to the encoder, which results in a highly compact design. The robust stainless steel cable is coated with polyamide.

The resolution of the measuring system is 30 micrometers per step. The contact-free measuring sensor stage of the MCD doesn't have any abrasion. So in comparison with potentiometer based sensor stages, the linearity remains stable even after 1 Million measuring cycles. The Sensors can be connected via standard serial SSI interface or via CANopen bus interface. An analog interface (0-5V or 4-20mA) provides for a drop-in replacement for potentiometers.
