Button NEF30-UDR2Y red W0-NEF30-UDR 2Y C

Application and Construction

The NEF30-UDR2Y C control button is an element used to start, stop or indicate the operating status of devices and machines. It is designed for mounting in 30.5 mm diameter holes in control panels, machine and device housings. The construction based on a metal body ensures durability and resistance to mechanical damage. The UDR model is characterized by latching – the button remains in the active position after being pressed until it is unlocked by rotating it.

Durability and Protection

The NEF30-UDR2Y C button is designed to operate in harsh industrial conditions. It meets the IP66 standard, which means complete protection against a water jet and dust. The rated insulation voltage is 500V, and the withstand limited current reaches 1000A, which guarantees safety and reliable operation. Additionally, high shock resistance (2500V) increases its durability in demanding applications.

Mounting and Configuration

This button is compatible with EF30 series connecting elements, allowing it to be adapted to individual installation needs. It is possible to configure with up to six current paths (NO/NC), which provides great flexibility in designing control systems. Mounting is simple and intuitive thanks to standard mounting holes. It is important to maintain minimum clearances during installation to ensure proper ventilation and avoid overheating.
