CANopen, Devicenet, J1939

Draw-wire sensors for commercial and industrial use

Posital (Germany) has introduced the Linarix draw-wire sensors. They are available with a range of interfaces including CANopen, Devicenet, and J1939.

THE SENSORS ARE BASED ON MICROPROCESSOR-CONTROLLED MAGNETIC ROTATIONSENSORS that can be programmed. Users can set system parameters such as the measurement range. Push buttons and LED indicators facilitate these operations. This feature can be used to ensure that the full scale of the output signal (voltage or current) matches the limits of mechanical travel or to set the device to match the characteristics of the string pot that it is replacing, thereby minimizing the need to re-program the control system.

These draw wire systems come with a contact-free magnetic design. They feature a current or a voltage output, but can optionally also be equipped with a range of digital interfaces such as CANopen, Devicenet, J1939, Ethernet, and more. The company’s product finder tool helps users configure draw wire systems according to their specifications, including connector and cable types.

Draw wire sensors (also known as string encoders or wire actuated encoders) are used in applications that require linear motion to be monitored for system control or to ensure safety. Draw wire sensors based on magnetic rotary encoders are a solution for monitoring linear motion over a range of up to 10 m. They are an alternative to potentiometer-based string pots for a range of applications, including material handling, construction machinery, overhead gantries, cranes and medical equipment. The sensors provide precise measurements because of the inherent accuracy of the absolute encoders and the rugged construction ensures performance even under extreme conditions.
