M12 wire-to-board connector

16 July 2014 Interconnection

ERNI has expanded its M12 wire-to-board (WTB) connector product offering to include a centre-axis, PCB edge mounting model that saves significant board space when compared to top mount, right angle connectors. The M12 90-Degree PCB connector system mates according to IEC 60076-2-101 and is IP67-rated in the mated and locked position.

The parts are well suited for a wide variety of applications such as fill level, range, measuring and pressure sensors, light barriers, position switches, fieldbus, industrial equipment and peripheral equipment. Part of ERNI’s modular circular connector portfolio, it features multiple configurations for flexible integration. Male direct integration versions for sensor pipes can be front mounted/loaded into the pipe, ‘snapped’ into the pipe or a rear mount/loaded version may also be utilised.

Available in 3-, 4- and 5-pins versions, with 8-pin shielded and unshielded models in development, the M12 right angle WTB connectors also have an early mate / first break option. They are available with A, B and D coding. The required threaded metal shells for panels, O-rings and cordsets are also available.

Plug and socket PCB layouts are identical with a different PCB layout for each thickness: 1,0 mm, 1,6 mm and 2,0 mm. Integrated PWB support pegs allow the connector to be centred on the PWB edge for each nominal thickness. PWB thicknesses between the nominal 1,0 mm to 1,6 mm and 1,6 mm to 2,0 mm can be realised if non-centric alignment between the PWB and connector is possible.

The connectors are suitable for automated pick-and-place assembly and reflow solder processing through SMT production lines, and are delivered in tape-and-reel packaging for automated processing.
