Interference-free transmission in confined spaces

Reliable signal transmission in electromagnetically exposed industrial environments requires sophisticated and comprehensive EMC concepts. By means of Binder’s 360°-shielded M5 connectors, these can now also be implemented in miniaturised applications.

The 707 series products are available in 3- and 4-pin versions, with both straight and angled cable outlets. The connectors are equipped with screw locking and standardised according to the design specification DIN EN 61076-2-105. They are particularly suitable for use under the influence of high-frequency electric and magnetic fields. Their 360° shielding enables shielding attenuation values of 60 dB at frequencies around 1 GHz.

The interference-free operation of sensitive electronic modules is a fundamental requirement in the field of automation technology. Machines and systems include high-frequency circuits, for example in switched-mode power supplies, which can affect the circuits of surrounding controllers with noise due to coupling effects. The signal paths of sensors and actuators are also subject to electromagnetic interference (EMI). Besides the automation components, shielding concepts that offer comprehensive EMI protection include the sensor-actuator cabling and all signal lines; they also extend to the electromechanical connectivity solutions, which must be integrated into the respective shielding concept.

As automation components continue to miniaturize, small, robust and flexible signal connectors are gaining in importance. Above all, the space-saving M5 size, equipped with screw locking, is suitable here as a reliable connection solution. The development of effective shielding for these particularly small connectors is very demanding, for example with regard to connecting the shield to the housing and in terms of mechanical robustness, for example under shock and vibration loads.

The M5 products of the binder 707 series have been subject to extensive laboratory tests, which confirm both the required shielding performance and the reliable function of the products under typical industrial loads. Their range of application extends from ultrasonic sensors and miniature valves to instrumentation and analytic devices. Further application examples can be found in signal transmission for cobots or in drones as well as in e-scooters and e-bikes.
