Depending on requirements, CEAG Ex-cable glands are available in moulded plastic and metal versions. The plastic cable glands have metric screw-in threads. The special advantage of ex-protected cable glands is the large cable clamping area.
CEAG Ex-metal cable glands are used for feeding cables into metal or explosion-protected enclosures. The metal glands are also available in a flameproof version and can be subjected to high mechanical, chemical and thermal loads.
