Push-button enclosure Rittal HD 1686.600 stainless steel, 6 x 22.5 mm, metallic

Rittal HD 1686.600 is a stainless-steel push-button enclosure manufactured from material grade 1.4301 with a metallic finish. The housing provides six 22.5 mm cut-outs arranged for control and signaling elements and is designed for demanding industrial environments where hygiene and corrosion resistance are important. The enclosure features an all-round gap-free silicone seal between body and cover and a hygiene-compliant quick-release hexagon fastener. Its robust stainless-steel construction and purpose-oriented layout make it suitable for machine control and operator stations in food and beverage, pharmaceutical, and other hygienic production areas.

Advantages

The stainless-steel construction ensures corrosion resistance and longevity in humid or washdown environments while the metallic finish offers a professional, easy-to-clean surface. The integrated gap-free silicone seal prevents ingress of liquids and contaminants along the enclosure perimeter. The quick-release hexagon fastener enables tool-assisted but rapid access for maintenance and cleaning, and the pre-cut six 22.5 mm openings simplify installation of standard push-buttons and pilot lights without additional machining.

Suitable for

• Machine control panels and operator stations
• Food and beverage production lines requiring hygiene-compliant enclosures
• Pharmaceutical and clean production areas with regular washdown
• Industrial applications requiring corrosion-resistant control housings

When it may not be suitable

This enclosure is intended for six 22.5 mm control elements; it is not suitable if your design requires different cut-out sizes, a larger number of actuators, or integrated electronic modules that need custom internal mounting features. It also does not replace a fully sealed instrument housing for submerged or high-pressure washdown applications unless additional sealing and installation measures are specified.

Key specifications

• Material: stainless steel (grade 1.4301)
• Finish: metallic
• Number of cut-outs: 6
• Cut-out diameter: 22.5 mm (for standard push-buttons and pilot lights)
• Seal: all-round gap-free silicone seal between enclosure and cover
• Fastening: hygiene-compliant quick-release hexagon fastener
• Application focus: hygiene-sensitive and washdown-capable industrial environments

How to use

Mount the enclosure at the intended control station and secure it using appropriate panel fasteners. Install standard 22.5 mm push-buttons, pilot lights or emergency stops into the pre-cut holes and fix the actuators according to the component manufacturers' instructions. Ensure the silicone seal is correctly seated before closing the cover and tighten the quick-release hexagon fastener to the recommended torque to maintain the gap-free seal. Follow local wiring and safety regulations when connecting control wiring, and allow sufficient internal space for wiring and terminals.

What to consider before purchase

• Verify compatibility of chosen 22.5 mm control elements with the 22.5 mm cut-outs and panel thickness.
• Confirm stainless-steel grade 1.4301 meets corrosion resistance requirements for your environment.
• Evaluate whether six cut-outs match your control layout or if a different enclosure size is needed.
• Check mounting and sealing requirements for washdown or hygienic certification in your facility.

Usage recommendations

For hygienic environments, clean the metallic surface and silicone seal regularly with manufacturer-approved cleaning agents and inspect the quick-release fastener for secure engagement after cleaning cycles. Use standard 22.5 mm control devices and follow component installation instructions to preserve ingress protection and operational reliability.
