The IP68 contact block makes it possible to provide many variants of switches with IP68 protection.
The contact block is a closed assembly consisting of a contact block of the S series in regular or gold-plated design and a metal mounting flange. The yellow and green wires are pre-wired for the NO connection and the white and brown wires are pre-wired for the NC connection. Special connections can be realized on request. The contact block can be combined with all standard actuators.
The contact block is characterized by:
- easy to install
- safe handling
- rugged design
- Protection class IP67
- Resistant to high-pressure cleaning in accordance with IP69k
- reinforced impact resistance
- Resistance to salt, oil and detergents
- overmoulded connecting cable
- Connection cable 0,5mm2, 4 wires, 1m long
