LINARIX linear position sensor

POSITAL-FRABA Inc. September 2, 2022

POSITAL LINARIX linear positions sensors have been updated with extra-heavy-duty draw-wire mechanisms and with a convenient pre-scaling option for devices with analog communications interfaces. LINARIX position sensors are ideal for a wide variety of applications, including medical equipment, packaging and materials handling systems, forklifts, overhead gantries, lifts and flow control gates in water management systems. LINARIX sensors combine a multi-turn absolute rotary encoder with a robust 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. These devices are both accurate and durable, with draw-wire mechanisms that are rated for over one million cycles. Furthermore, the rotary encoders are based on non-contacting magnetic measurement technologies that are immune to the wear or corrosion that can degrade the accuracy of potentiometer-based draw-wire devices. Analog, DeviceNet, CANopen and SSI output interfaces are available. Sensors with analog output can be programmed in the factory so that the output range (e.g., 0 – 10 V, 4 – 20 mA) is scaled to span the range of distances that the device will encounter when it is in service. This will simplify setup, improve the accuracy of analog control systems. New heavy-duty draw wire mechanisms are rated at IP69K and can withstand high-pressure water jets – a big plus for construction equipment requiring frequent cleaning!
