Metal Enclosure Component – Electrical Equipment Manufacturing

Component Specifications

Definition

A precision-engineered metal enclosure designed specifically for industrial Ethernet switches, providing electromagnetic interference (EMI) shielding, physical protection against environmental hazards, thermal management through heat dissipation, and structural support for internal components in harsh industrial environments.

Working Principle

Functions as a Faraday cage to block external electromagnetic interference while containing internal emissions, provides IP-rated protection against dust and liquids, dissipates heat through conductive metal surfaces, and offers mechanical protection against impacts and vibrations through rigid metal construction.

Materials

Galvanized steel (1.2-2.0mm thickness), aluminum alloy (6061-T6 or 5052), or stainless steel (304/316) with powder-coated finish (RAL 7035 or custom colors), corrosion-resistant plating, and EMI gasketing materials.

Technical Parameters

Finish Powder-coated, anodized, or galvanized
Weight 1.5-5.0kg depending on size
Mounting DIN-rail or panel mount
IP Rating IP65/IP67
Dimensions Standard 19" rack widths
EMI Shielding ≥40dB at 1GHz
Operating Temperature -40°C to +85°C

Standards

IEC 60529, IEC 61000-6-2, IEC 61000-6-4, UL 508, NEMA 250
