Rittal SZ 2411.651 polyamide cable gland M40 light grey, pack of 5

Rittal SZ 2411.651 is a polyamide cable gland in light grey supplied as a pack of five. Designed for M40x1.5 threaded openings, this cable gland provides a protected entry point for electrical cables into enclosures and control cabinets. The polyamide (PA) construction offers chemical and mechanical resistance appropriate for industrial and commercial installations, while integrated clamping membranes deliver reliable tightening and strain relief to protect conductors from mechanical stress.

Advantages

The Rittal polyamide cable gland combines a robust thermoplastic material with a standardized M40x1.5 thread for straightforward fitting into compatible glands or enclosure entries. Its integrated clamping membranes ensure consistent sealing and strain relief across different cable diameters within the specified range, reducing the likelihood of cable movement or damage. Being delivered as a pack of five supports multiple installations or spare part stock for maintenance.

Suitable for

• Cable entry and sealing in electrical enclosures and control cabinets
• Industrial and commercial installations requiring durable plastic glands
• Applications needing strain relief for power and control cables
• Maintenance or retrofit projects where multiple glands are required

When it may not be suitable

This polyamide cable gland is intended for use with M40x1.5 threaded entries and may not fit enclosures with different thread standards or metric sizes. It is a plastic gland and therefore may not provide the same temperature resistance, mechanical strength or electromagnetic properties as metal cable glands; for high-temperature, heavy mechanical load or EMC-critical applications a metal gland should be considered instead.

Key specifications

• Material: polyamide (PA)
• Color: light grey
• Thread size: M40 x 1.5
• Pack quantity: 5 pieces
• Function: cable entry sealing with integrated clamping membranes for strain relief

How to use

Drill or use the enclosure’s M40x1.5 threaded entry, insert the cable gland and screw it into the threaded hole until the sealing face is seated. Pass the cable through the gland and tighten the cap to compress the integrated clamping membrane around the cable, ensuring a snug fit that provides sealing and strain relief. Verify the cable diameter falls within the gland’s clamping range and confirm a secure mechanical hold without over-tightening the cap to avoid damage to the cable insulation or the membrane.

What to consider before purchase

• Verify enclosure entry thread is M40 x 1.5 and compatible with metric fittings
• Check cable outer diameter is within the gland’s clamping range
• Assess whether polyamide material meets temperature, chemical and mechanical requirements of your application

Usage recommendations

For reliable performance, install the gland following manufacturer torque guidance where available, ensure the cable sheath is clean and undamaged before sealing, and use multiple glands from the same material batch for uniform ageing in grouped installations.
