Through-wall plug connection

By simply attaching the adapter to a ZSTK coupling, a housing lead-through can be realised. The multi-pole units latch in sheet metal openings. Pressure on the inner slide fixes them in position. The outer plug connector can be fitted with an additional latch element. The rectangular wall opening always has the same width; its length varies with the size of coupling and connector which depends on the number of poles.

The modular, pluggable connection system facilitates the connection or exchange of pre-assembled functional units, thereby minimising the mounting effort. It is suitable for rated currents to 24A and rated voltages to 500V. Users can wire the machine side and the control cabinet side, pre-commission the application, easily disconnect it for transport, and simply re-plug it for commissioning.

Components can be individually configured, combined and coded according to application-specific requirements. Snap-on locking latches are available to prevent unauthorised handling. Wires with 0.5 to 4 mm² cross-sections are reliably contacted via tension-spring connections. For additional mechanical resilience, e.g. in mobile applications, a strain relief mechanism can be snapped on.
