Small spaces are always problematic for a designer but reliable signal transmission in electromagnetically exposed industrial environments requires sophisticated and comprehensive EMC concepts, said binder. It has developed the 360 degree-shielded M5 connectors which can be implemented in miniaturised applications that have little available space, such as in robotics, sensor technology, metrology and analytics.
The specialist in industrial circular connectors has complemented its M5 portfolio with connectors featuring 360 degree shielding. This 707 series is available in three- and four-pin versions, with both straight and angled cable outlets.
The M5 circular connectors feature 360 degree shielding and screw locking. They operate at a rated voltage of 60V and a rated current of 1.0A and are able to withstand surge voltages of up to 1,500V.
Crimping and dip soldering are applied as termination techniques. They meet the requirements of IP67 protection and have an operating temperature range from -25 to +80 degrees C and are designed for a mechanical service life of more than 100 mating cycles.
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 in areas of high-frequency electric and magnetic fields. The 360 degree shielding enables shielding attenuation values of 60dB at frequencies around 1GHz.
The connectors are particularly suitable for automation where interference-free operation of sensitive electronic modules, for example 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 EMI.
In addition to the small size, meeting miniaturisation requirements, the M5 connectors have screw locking to ensure a reliable connection solution. It is essential that the shielding is precisely connected to the housing to be effective and must also be mechanically robust, e.g., 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, reported the company. Typical innovation areas which require shielding include ultrasonic sensors and miniature valves to instrumentation and analytic devices, and in signal transmission for cobots or in drones as well as in e-scooters and e-bikes.
binder is able to offer customer-specific variants of the shielded M5 connectors. Guido Werner, product manager at binder, commented: “As a result of the successful market launch, we have already received new concrete customer inquiries, based on which further M5 products are being developed.” By the end of this year, he said, there will be angled panel mount parts with dip solder contacts for PCB assembly and M5 variants that can be freely assembled in the field. “Next will be over-moulded cables, panel mount parts and field-wireable connectors in various designs in the M5 size, he added. The company believes this will make it the first manufacturer to offer a complete product portfolio in this size.
