Each module has a front panel that is 19 inches (482.6 mm) wide. However, an <em>EMC (Electromagnetic Compatibility)<\/em> <strong>19 inch cabinet<\/strong> goes several steps further.<\/p>\n<p>An <strong>EMC shielded enclosure<\/strong> is specifically engineered to prevent electromagnetic radiation from escaping the cabinet and to protect the internal components from external electromagnetic interference. This is typically achieved through a Faraday cage effect. Key features include:<\/p>\n<ul>\n<li><strong>Conductive Gasket Rack Design:<\/strong> Special conductive seals are used around doors and removable panels to ensure continuous electrical contact across the entire chassis.<\/li>\n<li><strong>Robust Grounding:<\/strong> A heavy-duty grounding system, such as a 4.0mm grounded copper plate, ensures that any stray electrical currents or EMI are safely directed to the earth.<\/li>\n<li><strong>Metal Construction:<\/strong> High-quality sheet steel construction that naturally attenuates electromagnetic waves.<\/li>\n<\/ul>\n<p>These cabinets comply with international standards such as <a href=\"https:\/\/webstore.iec.ch\/publication\/2583\" target=\"_blank\" rel=\"nofollow noopener\">IEC 60297<\/a> for mechanical dimensions, ensuring seamless integration of any standard <strong>industrial rackmount chassis<\/strong>.<\/p>\n<p><!-- Image 1 Placeholder --><\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-12029\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/04\/EMC-shielded-19-cabinet-rack-protecting-sensitive-electronics-in-an-industrial-data-center-1.jpg\" alt=\"EMC shielded 19 cabinet rack protecting sensitive electronics in an industrial data center.

Variable frequency drives (VFDs), large motors, welding equipment, and high-voltage switching generate significant EMI. If a <strong>PLC rack enclosure<\/strong> is not properly shielded, this interference can lead to:<\/p>\n<ul>\n<li><strong>Signal Degradation:<\/strong> Analog sensor readings can become skewed, leading to incorrect automated responses.<\/li>\n<li><strong>Data Loss:<\/strong> High-speed communication networks (like Industrial Ethernet or EtherCAT) can drop packets, causing network latency or disconnects.<\/li>\n<li><strong>Hardware Damage:<\/strong> Severe electromagnetic pulses can permanently damage sensitive microprocessors inside servers and PLCs.<\/li>\n<\/ul>\n<p>By utilizing an <strong>IP54 industrial enclosure<\/strong> with EMC capabilities, you not only protect against dust and splashing water but also create a secure electromagnetic environment.

What is the difference between a standard 19 inch cabinet and an EMC shielded enclosure?<\/strong><br \/>A standard cabinet provides physical protection, while an EMC shielded enclosure uses conductive gaskets, specialized metal construction, and robust grounding to block electromagnetic interference (EMI) from entering or leaving the cabinet.<\/p>\n<p><strong>2. Why is a 4.0mm grounding copper plate important?<\/strong><br \/>A thick grounding plate provides a very low-impedance path to earth. This is critical for safely dissipating fault currents and for ensuring that the EMC shielding functions correctly by draining electromagnetic noise.<\/p>\n<p><strong>3. Can the TPS 15U cabinet be moved easily?<\/strong><br \/>Yes, while it is a heavy-duty industrial rack (weighing up to 125 kg net), it offers optional height-adjustable castors (4x GD-80) with Fuma brand bearings, enhancing portability across the factory floor.<\/p>\n<p><strong>4. Are these cabinets suitable for PLC systems?<\/strong><br \/>Absolutely. They are ideal as a <strong>PLC rack enclosure<\/strong>. The inclusion of standard DIN rail components, ABB breakers, and FINDER relays makes them perfect for housing and protecting sensitive programmable logic controllers.<\/p>\n<\/section>\n<footer style=\"background: #2d5797; padding: 30px; border-radius: 14px; margin-top: 40px;\">\n<p style=\"color: #ffffff; font-size: 16px; line-height: 1.6; margin: 0;\"><strong>Next step:<\/strong> Protect your sensitive electronics with our robust, EMC-ready industrial enclosures.
