Right-angle M12 plug connectors

3 March 2010 Interconnection

Phoenix Contact’s two-part M12 plug connectors are available, effective immediately, in versions with angled contacts for mounting on printed circuit boards.

The product range includes 4-, 5-, and 8-pin connector and socket versions, available with shield contact to comply with fieldbus specifications. The necessary shield is directly connected to the PC board. The spring shield connecting plate ensures reliable and permanent contact to the housing panel.

The mounting technique is simple and cost effective: contact carriers – suitable for wave soldering – are clipped onto the PC board and soldered, and the M12 housing parts are screwed to the customer’s housing. The 1,6 mm thick PC board is then mounted. The contact carriers of the pre-soldered PC board are then pushed from the inside of the device through the pre-mounted connector housing.

For customised housings, the M12 screw connection can often be directly integrated into the housing contour. For these applications, the contact carriers can also be purchased without M12 screw connection. As a consequence, the M12 connection system can be used in die-cast housings.

The factory provided O ring on the contact carrier provides an additional sealing effect between the contact carrier and the M12 screw connection. This means that, when not inserted, the sensitive electronics inside the unit are not destroyed by the unwanted ingress of moisture. The new family of plug connectors is in compliance with IEC 61076-2-101 and fulfils the requirements of IP67 degree of protection.
