Flexible signal interfaces

Growing demand for compact interfaces for signal transmission

Compact, robust signal interfaces that can be used as flexibly as possible are particularly in demand in markets with pronounced miniaturization. With angled flange parts of the M5 design, Franz Binder GmbH & Co. Elektrische Bauelemente KG supports designers and developers in space-critical applications in automation, robotics and measurement and control technology.

The 3- or 4-pole connectors of the 707 series are equipped with dip solder contacts for PCB mounting, and a screw locking mechanism ensures the security of the connection. Plugged and locked, the interface meets IP68 protection.

As the markets for collaborative robots (cobots) and drones (Unmanned Aerial Vehicles, UAVs) expand, as well as for cameras for industrial image capture or for length measurement systems, the need for compact interfaces for signal transmission is growing. In these and related fields of application, highly specialized, individually tailored products are being designed on the one hand. On the other hand, maximum reliability is a core aspect of development here. Customer demands on connection technology therefore primarily address flexibility and robustness in use as well as consistently high component quality. The particularly space-saving M5 design with screw cap offers itself here as an extremely reliable connectivity solution. In the binder 707 series, the components are now also available in an angled flange design.

The angled M5 flange parts are equipped with slightly splayed positioning pins. Hardly visible to the naked eye, these ensure the best possible protection against twisting on the PCB even before the contacts are soldered. Another advantage is the deeper O-ring for sealing to the housing. When the flange part is connected, it is pressed against the housing as far as it will go, thus optimizing the sealing effect. Destruction of the sealing ring by overtightening is ruled out from the outset. The component width of the M5 flange parts is only 7.5 mm. This is significantly less than the usual dimensions for connectors, which facilitates use in confined spaces.
