New M12 SMT series of ruggedised connectors offer high functional reliability

Provertha has expanded its circular connector portfolio with the new M12 ruggedised connector series in straight and angled versions for PCB mounting using SMT connection technology. The ruggedised versions – optionally unshielded or shielded with a one-piece shield clip – feature robust, large-area SMT connections with a special contact design.

The company delivers everything required to optimise customised applications. It offers many products in all common codings and installation heights.

The new design of the ruggedised series combines customer requirements for high functional reliability (thanks to a special contact geometry) and optimum routing on the PCB – thanks to the option of routing the conductor tracks horizontally and vertically through and out of the connector on all four sides. The series with protection class IP67 was developed to ensure the highest connection reliability at the PCB connection contacts, for example under vibration or shock loads in accordance with IEC 61076-2-101 and -109 in a wide temperature range from -40C to +125C (without O-ring).

The straight connector features the lowest insertion height on the market at just 16mm and highly variable routing in four directions on the PCB. The connectors support the increasing trend towards miniaturisation with D-code and X-code versions for Ethernet switches and Gigabit Ethernet switches, and A-code versions for I/O boxes. The connectors permit for appreciable space savings even in small devices. Another component for miniaturisation is the new tamper-proof M12 installation housing, optionally for push-pull or screw locking. A special design allows the interfaces to be arranged close together with minimal spacing.

A key feature of the series is the contact design with an elastic connection contour and larger SMT connections, which, together with the geometry of the mounting brackets and four large-area connection pads, allow the absorption of high transverse and shear forces. The connectors, therefore, provide a high level of functional reliability, as this also prevents the SMT connections from breaking off under high stress.
