Industrial plugs and sockets

Extra low voltage

Our extra low voltage range offers Industrial plugs & sockets for
protection in areas with a high risk like swimming pools, wandering-
lead hand lamps, and other portable appliances for outdoor use.

Therefore our range includes products of IP44 and IP67.

Our range of Industrial plugs and sockets for ex-
tra low voltage covers voltages up to 50V AC or 120° 120° S2
DC and fulfills IEC 60309. Secondary key R1 T3

position of the secondary key is indicated by 1) The position of main key is defined as 6h (6 o´clock)
a number followed by a letter h (the hour position
or o´ clock position). The number is determined
by the position of the secondary key relative to
the main key, the position of which is defined as 6
o´clock. Non hour position is given for 20-25 V,
50-60 Hz, since there is no secondary key on
these plugs and sockets.
The width of the key is different for 16 A and 32
A plugs and sockets. In addition, there is a color
coding system: the cover or front part is violet on
20-25 V and white on 40-50 V plugs and sockets.
Plugs and sockets for direct current are grey.
