DIN Rail Mounted Electronic Enclosures

Altech DIN Rail enclosures make it easy to integrate PCB electronics into control panels by combining protection, functionality, and ready-to-wire terminals in one compact housing. These versatile enclosures are ideal for relays, timers, sensors, monitoring devices, transducers, and printed circuit boards, offering one of the most comprehensive selections in the industry with multiple sizes, cover styles, and terminal-to-board options.

Manufactured by DOLD, a trusted European leader in DIN enclosures and safety relays, Altech housings are built from flame-retardant, maintenance-free materials that ensure long-term durability while maintaining a clean, professional appearance. They are easy to assemble, mount on standard 35 mm DIN rails or panels, and meet international performance and safety standards.

For added flexibility, Altech offers customization including cutouts for switches or indicators, terminal marking for easier wiring, printed instructions, and even custom colors or configurations for OEM applications. With these options, your devices can be packaged attractively, safely, and tailored to your exact requirements.
