An electronic cabinet (also called an electrical enclosure, control cabinet, or distribution cabinet) is a protective housing that shelters electrical and electronic components — power distribution units, PLCs, circuit breakers, busbars, and wiring harnesses — from mechanical damage, dust, moisture, and electromagnetic interference. According to IEC 61439-1:2011 (Low-voltage switchgear and controlgear assemblies), a properly constructed enclosure must maintain its rated ingress protection and electrical clearances throughout its service life, ensuring personnel safety and system reliability.
The term electronic cabinet covers a broad family of metal enclosures engineered to house live electrical equipment. Key sub-categories include:
The table below consolidates the key parameters buyers and engineers specify when sourcing electronic cabinets, together with the applicable international standards. All dimensions and ratings shown are achievable within Jiafeng's standard production range; custom values are available on request.

Most enclosure suppliers ship a bare metal box. Jiafeng delivers a complete, tested electronic cabinet — wired, assembled, and documented — ready to install. Our vertically integrated facility in Jiashan, Zhejiang means every stage from steel coil to finished cabinet happens under ISO 9001 control, with one point of accountability and one quality system.
Fiber laser cutting (3,000–12,000 W), Salvagnini auto-bending, robotic welding — all in-house. Learn more about our sheet metal manufacturing capabilities.
5-axis machining centres achieve ±0.005 mm on brackets, gland plates, and mounting bosses. See our precision machining page for full equipment specs.
Level-5 assembly lines for wiring, PCB mounting, PLC commissioning, and burn-in testing. Full details on our electromechanical integration service.
Our in-house zinc plating line processes parts up to 3,000 × 750 × 1,500 mm and delivers 96–128-hour salt-spray performance per ASTM B117, critical for outdoor electronic cabinet installations.
Every electronic cabinet ships with full compliance documentation — Declaration of Conformity, test reports, material certs, and wiring diagrams — included in the quoted price, not as an add-on.
No fixed MOQ. Single prototype cabinets receive the same engineering attention as 10,000-piece production runs. Prototype lead time typically 2–4 weeks; production 4–10 weeks depending on complexity.
The terms are often used interchangeably, but technically: an enclosure is the bare metal or non-metallic box (per IEC 62262); a cabinet refers to a free-standing, door-bearing enclosure typically ≥ 600 mm tall; and a control panel or switchboard is the complete assembly including internal components, wiring, and labelling, governed by IEC 61439-1. Jiafeng manufactures all three categories, with the ability to supply a fully assembled and tested control cabinet rather than just the bare enclosure.
IP rating selection depends on the installation environment. As a rule of thumb: IP20 suffices for dry indoor locations; IP54 is the minimum for factory floors with coolant splash; IP65 is required for outdoor enclosures in rain exposure; IP67/IP68 for submersion risk. The sheet metal precision of door flanges and gasket grooves is the primary determinant of whether a cabinet achieves its target IP rating under IEC 60529 test conditions. Our CNC-bent door frames hold flange flatness within ±0.1 mm, a prerequisite for reliable IP65 sealing.
Yes. Our electromechanical integration service covers the complete build: DIN rail and busbar fitting, component mounting, cable harnessing, PLC commissioning, sensor calibration, and full functional testing per IPC-A-620 wiring standards. You receive a tested system, not a flat-pack.
For outdoor electronic cabinets the highest durability option is a combination of hot-dip galvanised steel (Zn coating ≥ 85 µm per EN ISO 1461) as the base material, followed by an epoxy primer and polyester powder coat (60–80 µm) in a UV-stable RAL colour. This system can deliver corrosion protection Class C3–C4 per ISO 12944. For stainless steel outdoor cabinets, passivation per ASTM A967 is standard. Our precision machining team can advise on material and finish selection during the DFM review stage.
Prototype cabinets (single unit to first article) typically take 2–4 weeks from drawing approval, depending on complexity of internal assembly. Production batches of 10–500 units run 4–8 weeks; larger volumes are scheduled on request. Because fabrication, surface treatment, and assembly are all in-house, there are no inter-supplier logistics delays. Expedite options are available at the quotation stage.
