Schalksmühle, May 17, 2018. Lumberg is currently starting up an all-new material group –
WG02 – for its high-performance IP67 circular connector with Quicklock. Quicklock releases the
latch with a rocker that snaps the 2- to 12-pin connectors firmly into the sockets, and
conveniently disengages the latch again with a little pressure from the finger.

The cable connector, cable socket and chassis socket (with a captive silicone cover) come in
three frame sizes with a 12, 16 or 20 mm diameter of the mating face for a rated current of 20
amps for the maximum performance version. Today’s cable connection caters to the frequently
requested larger cable diameters and ranges between 3 and 11.4 mm as a soldered version for
the new power connectors.
All dimensions feature a contact base, grip body and cap nut made of robust PBT (V0 UL94)
while the brass contact male wiring pins are generally gold-plated. The connector’s Quicklock is
made of a chromium zinc alloy for the different size models. All IP67 size models are designed
to withstand a temperature range of between -40 and +80 °C, which facilitates their use in highly
challenging environments.
The 20-frame size accommodates higher currents in particular. 2-pin to 4-pin versions master
rated currents of 20 amps for a rated voltage of 500 V and a surge voltage of up to 2,500 V AC
in confined spaces. The 5-pin to 7-pin models are ideal for 12 amps; 9-pin to 12-pin versions
perform best with 5 amps.

Our 2-pin to 6-pin versions in frame size 12 cater to rated currents of 5 amps, while the 7-pin
and 8-pin version pairs best with 3 amps with a rated voltage of 125 V and a rated surge voltage
of 1,500 V AC.

These new models are Lumberg’s response to the demand for performance connectors that are
assembled in the field and are used in test and measurement applications, but also in areas
such as apparatus and mechanical engineering, traffic management systems and studio and
stage technology, which call for IP67 dust and water impermeability standards.
