Cable glands form an important part of an industrial enclosure's cable entry system by securing incoming cables and helping preserve the enclosure's environmental protection. The integrated clamping membrane of the Rittal SZ 2411.851 provides even tightening around the cable while delivering strain relief that helps reduce mechanical loading on internal terminals and connections.
Its nickel-plated brass construction, wide operating temperature range and IP68 sealing performance make this gland suitable for demanding industrial environments. The M40 × 1.5 connection and 19–28 mm cable range make it particularly suitable for larger power, control and equipment cables entering industrial control cabinets and machinery.
