VT-SWA-LIN-1X/G10-1-K44

The VT-SWA-LIN-1X/G10-1-K44 is a linear displacement transducer module supplied by Bosch Rexroth Indramat for the VT-SWMA Modules series. It converts mechanical travel into a proportional voltage so that hydraulic or electric drives can report actual position to a controller in industrial automation systems that need closed-loop axis control. A Hall-effect sensor inside the unit detects magnetic field changes from the sliding magnet without contact wear.

The module delivers a calibration sensitivity of 750 mV/mm, meaning every millimeter of stroke changes the output by three-quarters of a volt, which simplifies scaling inside a PLC. Four signal paths are provided through a 4-pole connector, and field wiring mates with the keyed G4W1F plug to prevent cross-connection. When an external potentiometer is used for range adjustment, the maximum permissible angle induces only -2 V at the input, protecting upstream electronics from overtravel. Mechanical installation uses an M27 × 2 thread that allows the housing to screw into valve blocks or machine frames without additional brackets. Zero drift and span drift are each limited to less than 0.2 percent per 10 K, keeping calibration stable during normal machine temperature changes. The zero-setting circuit can pull the baseline down to −5 V for mid-stroke alignment.

An enclosure rated at IP65 seals the electronics against shop dust and directed water jets. The reference channel supplies -10 V to excitation circuits, and the module draws its operating power from a regulated 10 V source provided by the control cabinet. Sensor output leaves the housing through the dedicated G4A5M connector, keeping signal and power cabling separate. The sealed housing supports operation near hydraulic equipment where airborne particles or occasional water exposure may occur. Stable calibration helps the controller interpret small position changes during repeated movements. The transducer provides position feedback in presses, injection molding machines, and servo-hydraulic cylinders that experience frequent cycles and varying ambient conditions.
