Rittal HD 1684.630 stainless steel control enclosure for 4 pushbuttons, Metallic finish, material 1.4301

The Rittal HD 1684.630 stainless steel control enclosure is a compact metallic-finish housing designed for mounting four 30.5 mm pushbuttons. Constructed from corrosion-resistant stainless steel (material 1.4301), the enclosure provides a hygienic, robust solution for operator interfaces in manufacturing, machinery and automation environments. The housing includes precision cut-outs for switches and an all‑round gap‑free silicone seal between the enclosure and cover to support washdown and hygiene requirements. A hygiene‑compliant quick‑release hexagon fastener enables tool‑less access for maintenance while maintaining a secure closure during operation.

Advantages

The stainless steel construction ensures durability and resistance to corrosion in demanding industrial settings. The metallic finish offers a clean, professional appearance while the preformed cut-outs simplify installation of four 30.5 mm pushbuttons. The gap‑free silicone seal around the cover improves protection against ingress and supports hygienic cleaning procedures. The quick‑release hexagon fastener is designed for frequent access without compromising enclosure integrity.

Suitable for

• Control panels and operator stations in machinery and automation systems
• Food and beverage production environments requiring hygiene-compliant enclosures
• Applications requiring four 30.5 mm pushbutton interfaces
• Areas where corrosion resistance and easy cleaning are necessary

When it may not be suitable

This enclosure is intended specifically for four 30.5 mm pushbuttons and may not be appropriate if your design requires different switch sizes, additional indicators, or larger control components. It is not a full electrical distribution cabinet; users requiring extensive internal mounting space, DIN-rail accessories or high-voltage separation should select a larger or different enclosure type.

Key specifications

• Material: stainless steel (material 1.4301)
• Finish: metallic
• Cut-outs: configured for four 30.5 mm pushbuttons
• Seal: all‑round gap‑free silicone seal between enclosure and cover
• Fastening: hygiene‑compliant quick‑release hexagon fastener for cover
• Application focus: control housing for operator interfaces, hygiene-sensitive environments

How to use

Mount the enclosure on a suitable panel or surface using appropriate fasteners and alignment. Install the four 30.5 mm pushbuttons into the preformed cut-outs according to the switch manufacturer’s mounting instructions, ensuring correct orientation and contact wiring. Securely seat the gap‑free silicone seal and close the cover using the quick‑release hexagon fastener; tighten to manufacturer‑recommended torque where specified. Perform wiring and functional tests before placing the control assembly into service, and follow site safety and lockout procedures during installation and maintenance.

What to consider before purchase

• Confirm that your control devices are 30.5 mm pushbuttons to match the cut-outs
• Evaluate internal space needs for wiring, terminals and any auxiliary components
• Verify suitability for your required IP rating and washdown or hygiene procedures
• Check mounting method and compatibility with your panel or machine frame

Usage recommendations

For hygiene‑sensitive environments, clean the exterior with approved detergents and avoid abrasive tools that can damage the silicone seal or stainless steel finish. Regularly inspect the seal and quick‑release fastener to ensure proper closure and replace seals if worn to maintain protection and hygiene compliance.
