Posital Linarix linear positions sensors are updated with extra-heavy-duty draw-wire mechanisms and a pre-scaling option for devices with analog communications interfaces. These sensors combine a multi-turn absolute rotary encoder with a draw-wire mechanism. As the wire is drawn off the device’s spool, the encoder measures shaft rotation and reports the result to the control system. Analog, DeviceNet, CANopen and SSI output interfaces are available.
Linarix sensors with analog output are programmed in the factory so that the output range (e.g., 0 – 10 V, 4 – 20 mA) spans the full measurement range of the draw wire mechanism. Customers also have the option of specifying the measurement range.
Ultra-heavy-duty versions are available with environmental protection ratings up to IP69k. Special models will be available with a built-in tilt sensor (inclinometer) to track both boom angle and extension from a single device.
