New SMT slimline circular connectors in M8 format

Provertha is extending its SMT solution portfolio for PCB connection with the Slimline M8 connector series. The new connectors are especially impressive thanks to the slim design, robust spring-elastic contact design and compatibility with the circular connectors of other leading manufacturers. The connectors for PCB mounting are available in two versions: unshielded or shielded with a one-piece shield clip using SMT connection technology. The company supplies customers with a reliable, compatible solution perfectly tailored to their applications – just completely 'Fitting your Application'.

Thanks to the spring-elastic contacts and an enlarged soldering surface connection to the contacts, the connectors attain at least 30% more resistance to the SMT connections breaking off under high mechanical stress compared to standard M8 SMT connectors. Their standard market-based footprint makes them compatible with the most used SMT circular connectors available on the market, and they can readily be employed as an alternative without changes to the PCB layout design.

The products can be utilised thanks to selectable codings (A-3, A-4, and D) flexibly – for example, for sensor-actuator applications in industrial automation, industrial Ethernet networks, and miniaturised applications exposed to high stress.

The female versions have a special contact design for high functional reliability under mechanical loads and are available with an overall height of 17mm. The small design makes the connectors ideal for applications with limited installation space. Another component for miniaturisation is the special design for close arrangement of the new tamper-proof M8 installation housing, which enables either push-pull or screw locking.

The connectors with IP67 protection class have very good technical characteristics, e.g., a wide temperature range from -40C to +125C and a high current carrying capacity. The new connectors are constructed of high-temperature-resistant, high-performance thermoplastic with high tracking resistance. The so-called Comparative Tracking Index (CTI value) – a measure of the tracking resistance of plastics – is over 600.

All M8 SMT Slimline connectors are designed for reliable processability in the fully automated SMT process thanks to the high-temperature-resistant pick-and-place suction pads and tape-and-reel packaging. Narrow tapes allow the connectors to be accommodated on the feeder bank of the placement machine and take up minimal space.

The new PCB connector solutions in M8 format complete the high-performance M12 SMT connectors of the ruggedised series and, the functionally reliable, market-compatible M12 SMT slimline series and the high-performance D-Sub connectors for PCB applications (TMC products).
