Control Enclosure Rittal HD 1686.630 Stainless Steel, for 6 Pushbuttons, Width 182 mm Height 242 mm

Rittal HD 1686.630 is a stainless steel control enclosure designed to accommodate up to six 30.5 mm pushbuttons in a compact front of 182 × 242 mm. Constructed from stainless steel 1.4301 and finished in a metallic colour, the housing provides corrosion resistance and a hygienic surface suitable for environments with strict cleanliness requirements. The enclosure features cut-outs for switches, an all-round gap-free silicone seal between enclosure and cover, and a hygiene-compliant quick-release hexagon fastener to simplify access while maintaining a sealed barrier.

Advantages

The enclosure combines a robust stainless steel structure with corrosion-resistant properties and a smooth finish that supports frequent cleaning. Its compact dimensions and preconfigured cut-outs make it straightforward to mount up to six 30.5 mm pushbuttons, while the gap-free silicone seal and hygienic fastener reduce ingress risk from liquids and contaminants. The metallic finish and 1.4301 material grade ensure long-term durability in industrial and hygienic applications.

Suitable for

• Industrial control panels and machine operator stations requiring stainless steel housings
• Food and beverage production areas where hygiene-compliant enclosures are required
• Applications needing a compact operator interface with up to six 30.5 mm pushbuttons
• Environments where corrosion resistance and ease of cleaning are important

When it may not be suitable

This enclosure is designed specifically for pushbuttons with a 30.5 mm diameter and for a maximum of six positions; it is not suitable for devices that require different cut-out sizes or a greater number of control elements. It is intended as a control interface housing and does not include internal components such as contact blocks, switches or wiring.

Key specifications

• Material: Stainless steel 1.4301 (AISI 304 equivalent)
• Front dimensions (W × H): 182 mm × 242 mm
• Capacity: Up to 6 pushbuttons, 30.5 mm diameter each
• Seal: All-round gap-free silicone seal between enclosure and cover
• Fastening: Hygiene-compliant quick-release hexagon fastener
• Finish: Metallic colour, smooth surface suitable for cleaning

How to use

Mount the enclosure on a suitable panel or surface using appropriate mounting hardware. Install 30.5 mm pushbutton units into the pre-cut holes from the front, and secure contact blocks and wiring from the rear according to the switch manufacturers' instructions. Ensure the silicone seal is correctly positioned before closing the cover and tighten the quick-release hexagon fastener to maintain the sealed joint. Follow applicable electrical installation standards and safety procedures when wiring and commissioning the control interface.

What to consider before purchase

• Confirm pushbutton diameter is 30.5 mm and total number of control elements does not exceed six
• Check material suitability for the specific environment (stainless steel 1.4301) and any chemical exposure
• Verify required ingress protection or additional sealing needs beyond the silicone gasket
• Consider whether accessory components (contact blocks, lens covers, labels) are required separately

Usage recommendations

For hygienic areas, use compatible cleaning agents and follow recommended cleaning intervals to preserve the silicone seal and stainless steel surface. When installing, route wiring to minimise strain on connections and to maintain the integrity of the sealed enclosure. Replace silicone seals if damaged to retain the enclosure's protective properties.
