• Waterproof Plastic 10-5: 200x120x75 mm
• Aluminum Enclosure 11A-4: 222x146x78 mm
• DIN Rail Enclosure 14-7: 145x90x72 mm
• Terminal Enclosure 15-1: 80x72x112 mm

Additional dimension notes include distinctions between interior and exterior measurements, compatibility with rack units (U), and horizontal pitch (HP) standards.

3. Customization and Modularity

• Many series offer customizable dimensions to fit specific application needs.
• Modular designs, especially in DIN rail terminal enclosures, feature snap-fit assembly for ease of installation.
• Options for terminal blocks on one or both sides, LCD window integration, battery compartments, and panel holes enhance flexibility.

4. Special Features and Notes

• Thickness measurements often exclude front/rear frames and panels.
• Some models are marked "Not for sale," indicating internal or special use only.
• Cable gland specifications ensure proper sealing and cable management by matching thread sizes and cable diameters.
• Waterproof and wall-mounting enclosures include locking devices and clear lid options for visibility and protection.
• Plastic enclosures may have color coding (black, orange, blue, green) and surface patterns or logos.

5. Manufacturer Information

Changhe has over 20 years of experience and offers a broad product range with modern production capabilities. The company provides a "one stop solution" for enclosure customization, covering waterproof, protective, DIN rail, aluminum extruded, desktop, and CATV amplifier enclosures.
