Cable gland Rittal SZ 2411.831 Nickel Brass M25 x 1.5, pack of 10

Rittal SZ 2411.831 is a nickel‑plated brass cable gland with metric thread M25 x 1.5, supplied as a pack of 10. It provides a metal, corrosion‑resistant entry point for cables into electrical enclosures and control cabinets, offering mechanical protection and reliable strain relief. The integrated clamping membrane permits safe tightening while protecting cable jackets during installation.

Advantages

The nickel brass construction combines mechanical strength with enhanced corrosion resistance compared with unplated brass. The integrated clamping membrane ensures cable‑friendly strain relief and a secure fit without additional inserts. Being a metal gland, it offers improved durability and electromagnetic shielding potential compared with plastic alternatives. Supplied in a pack of ten, it supports multiple installations or spare parts stock.

Suitable for

• Sealing and strain relief of single cables entering electrical enclosures and control cabinets.
• Industrial installations requiring metal glands with corrosion resistance.
• Applications where a metric M25 x 1.5 threaded entry is required.
• Situations needing durable, reusable cable fittings or spare parts supply.

When it may not be suitable

This metal cable gland may not be the best choice for applications that strictly require non‑metallic fittings for chemical compatibility or electrical isolation. It is also not suitable for cable diameters outside the clamping range designed for M25 glands, or for installations where specific ingress protection ratings and cable sealing compounds are mandated beyond the gland’s inherent capability.

Key specifications

• Material: nickel‑plated brass for corrosion resistance and mechanical strength
• Thread: metric M25 x 1.5
• Pack content: 10 cable glands
• Feature: integrated clamping membrane for cable‑friendly strain relief

How to use

Drill or use the prepared M25 threaded entry in the enclosure. Insert the gland body through the hole and tighten the locknut or secure according to the enclosure’s design. Pass the cable through the gland, then tighten the outer cap to compress the clamping membrane around the cable jacket, ensuring firm strain relief without over‑compressing the cable. Verify mechanical hold and, if required, test for sealing performance according to the installation standard used.

What to consider before purchase

• Confirm that M25 x 1.5 thread matches the enclosure entry or available adapter.
• Check the cable outer diameter range compatible with the gland’s clamping membrane.
• Assess whether a metal gland is appropriate regarding grounding, EMI, and chemical exposure.
• Ensure the pack quantity (10 pieces) fits project needs or spare part policies.

Usage recommendations

For reliable performance, torque the gland to the manufacturer’s recommended tightening values and avoid overtightening. Use compatible locknuts or sealing washers if required by the enclosure, and periodically inspect glands in harsh environments for signs of corrosion or mechanical wear.
