Modular System GWconnect Heavy Duty Connector (HDC) Modular System allows users to design and assemble connectors to meet a designer's specific requirements. The system is made of a support frame and a mobile element to block the modular inserts. Specific holes in the support frame allow the insertion of single and double modules, and the mobile element allows a steady fastening of the modules with lateral scrolling. Captive screws allow the modular connector to become a monoblock structure resistant to impacts and vibrations, and resistant to compression and traction when coupling male and female inserts. GWconnect HDC Modular System is compatible with all HDC enclosures and DIN rail supports and is available in frame sizes 10A, 6B, 10B, 16B, 24B 32B (2x16B), and 48B (2x24B).
