Case 19" 3HE SCHROFF 20860-126 per elettronica da montaggio rack

SCHROFF 20860-126 is a 19-inch 3U enclosure engineered for rack-mounted electronics, offering a standardized chassis for modules, instruments and subracks that conform to 19-inch rack dimensions. The enclosure provides a compact, uniform housing that supports organized installation, mechanical protection and straightforward cable routing for industrial, telecom and laboratory equipment.

Advantages

The 19-inch 3U enclosure delivers a balance of compact size and mounting compatibility, enabling easy integration into standard rack systems. Its sheet-metal construction ensures mechanical stability and EMI shielding where applicable, while front and rear mounting provisions support secure fixation of modules and connectors. The design facilitates airflow management and cable access without altering the rack footprint.

Suitable for

• Mounting modular electronic boards and instrumentation in 19-inch racks
• Industrial control units and automation components
• Telecommunication and network equipment in rack cabinets
• Laboratory measurement and test instruments requiring rack integration

Key specifications

• Format: 19-inch rack-compatible chassis
• Height: 3U (standard rack unit height)
• Construction: metal enclosure providing mechanical protection
• Mounting: front and rear panel mounting provisions for modules and connectors
• Cable management: cutouts and access points for routing cables
• Cooling: provisions for passive airflow and possible fan mounting depending on configuration
• Front panel: space for controls, indicators or connector panels

How to use

Install the enclosure into a compatible 19-inch rack using appropriate rack screws and rails. Fit modules, PCBs or instrument assemblies into the provided mounting guides and secure them to the front and rear mounting points as required. Route power and signal cables through the designated cutouts and secure them to prevent strain on connectors. If active cooling is necessary, install fans or use rack airflow guidance in accordance with system thermal requirements. Verify mechanical fastenings and electrical connections before powering the assembled unit.

Recommendations

Choose front panels and internal mounting kits that match the module dimensions to ensure secure fixation. Plan cable routing to maintain airflow paths and avoid blocking ventilation. For installations in electrically noisy environments, consider grounding and additional EMI measures consistent with system requirements.
