Limit switch D-429 A37-0000

Limit switch – a reliable safety and control element

This D-429 type limit switch is a reliable device designed for use in signaling and safety circuits. Its construction based on a durable metal housing with a powder-coated finish ensures durability and resistance to mechanical damage. The switch is activated by force acting on the dome plunger, which causes the contacts to switch. When the force is released, the contacts return to their initial position thanks to the built-in spring.

Construction and application

The D-429 switch is characterized by delayed-action contacts, which means it reacts with a delay to short-term current surges. This makes it perfect for applications where current shocks occur, e.g. when starting motors. The rated operating current is 4A for both AC-15 (230V) and DC-13 (24V) circuits, making it a universal solution for many industrial applications. Equipped with a PG cable gland, it allows for easy and safe connection of wires. The IP40 protection class provides protection against access to internal components and environmental influences.

Key features and benefits
