Cable transducer

Measuring linear motion with CANopen

Baumer’s (Germany) GCA5 series is suited for use in cramped installation conditions. The cable transducers are available with an integrated CANopen interface.

The compact cable transducers of the GCA5 series aim to offer maximum robustness in demanding applications. The housing of impact-resistant plastic, the corrosion-proof stainless steel cable with abrasion-resistant nylon sheath, and the non-contact wear-free magnetic sensing make them a suitable choice for reliable and low-maintenance deployment in harsh environments. Thanks to the three-chamber-principle design, both electronics and stainless steel spring are hermetically encapsulated against the cable drum. The integrated flexible dirt skimmer at the cable inlet is an additional protection against humidity and ingress of other harmful environmental substances.

The cable transducers feature a maximum measuring range of 4700 mm and are available either with integrated CANopen interface or analog output from 0,5 VDC to 4,5 VDC. The CANopen variant provides additionally redundant position sensing and hence simplifies function monitoring at control level. Housing protection IP67 (cable inlet IP54), shock resistant up to 50 g, vibration proof up to 10 g, and the extended temperature range from -40 °C to +85 °C make the cable transducers particularly robust and resistant against temperature fluctuations and all kinds of soiling.

The cable transducers offer a narrow design and shallow installation depth of 65 mm, which allows installation in cramped spaces – which prevail in mobile machinery and utility or transport vehicles. Cable transducers series have been standing the test of time in outrigger positioning at mobile cranes and telehandlers as well as height positioning at floor conveyor trucks and stacker cranes. According to Baumer, they are the easiest, most reliable, and cost-efficient way to measure linear motion within a path of 0,5 m to 50 m.
