Stainless steel control pushbutton enclosure Rittal HD 1681.630 for 1 pushbutton, material 1.4301

Rittal HD 1681.630 is a stainless steel control pushbutton enclosure made from material 1.4301, designed to accept a single 30.5 mm control pushbutton. The enclosure offers a corrosion-resistant housing with a compact footprint and robust metal construction tailored for industrial control panels, operator stations and environments with high hygiene requirements. It features an all-round gap-free silicone seal between the enclosure and cover and a hygiene-compliant quick-release hexagon fastener, providing a closed, easy-to-clean surface suitable for food-processing, beverage and marine applications.

Advantages

The enclosure's stainless steel 1.4301 construction provides resistance to corrosion and chemical cleaning agents commonly used in hygienic environments. The compact design with a dedicated cut-out for a 30.5 mm pushbutton simplifies installation and ensures a neat panel appearance. The gap-free silicone seal and hygiene-compliant quick-release fastener reduce crevices where dirt and bacteria may accumulate, while the metal housing increases mechanical protection and thermal stability compared to plastic alternatives.

Suitable for

• Food-processing and beverage production lines where stainless surfaces and easy cleaning are required
• Marine and coastal installations with exposure to moisture and corrosive atmospheres
• Industrial control panels and operator stations requiring a single 30.5 mm pushbutton
• Hygienic environments such as pharmaceutical handling areas and clean production zones

When it may not be suitable

This enclosure is intended for a single 30.5 mm pushbutton; it is not suitable when multiple controls or larger operator interfaces are required. It is a compact metal housing and may be heavier than plastic alternatives, so mounting considerations and support must be checked for weight-sensitive installations.

• Material: stainless steel (1.4301)
• Number of cut-outs: 1 for 30.5 mm pushbutton
• Sealing: all-round gap-free silicone seal between enclosure and cover
• Fastening: hygiene-compliant quick-release hexagon fastener
• Application environment: hygienic, food and beverage, marine, industrial
• Construction: compact, corrosion-resistant metal housing

How to use

Mount the enclosure on a suitable panel or surface and fit the 30.5 mm pushbutton into the prepared cut-out. Secure the cover using the quick-release hexagon fastener; ensure the silicone seal sits correctly around the enclosure perimeter to maintain a gap-free closure. Connect the electrical wiring to the installed pushbutton according to the button manufacturer’s instructions and applicable electrical standards. For hygienic environments, clean the stainless surface and seal regularly using compatible cleaning agents and methods to maintain corrosion resistance and hygiene.

What to consider before purchase

• Confirm the control device diameter is 30.5 mm and compatible with the enclosure cut-out
• Assess mounting location and support for the metal enclosure weight compared with plastic alternatives
• Verify compatibility with local electrical and hygiene regulations for your application
• Ensure cleaning methods and chemicals used in your process are suitable for stainless steel 1.4301

Usage recommendations
