What voltage supply is needed for operation and what does it mean for performance?

The switch operates at a supply voltage of 24V DC, ensuring it is suitable for various industrial applications while providing reliable performance without excessive power consumption.

How does the IP67 rating affect the switch's usability?

The IP67 rating means the switch is dust-tight and can withstand immersion in water up to 1 metre for 30 minutes, ensuring functionality in harsh environments.

What distinguishes the NO NC safety contacts from standard contacts?

The NO NC safety contacts allow for immediate detection of faults, improving safety by providing dual types of circuit configurations that enhance the reliability of the safety interlock system.

What is the significance of having a key holding force of 1,300 N?

A key holding force of 1,300 N ensures that the door remains securely closed under heavy loads, minimising the risk of accidental access or operation of machinery during maintenance.

How does the plastic housing contribute to the switch's overall functionality?

The plastic housing is lightweight yet sturdy, protecting internal components from environmental factors while facilitating easier installation and reducing wear compared to metal alternatives.
