Full details
The Hensel Cable Gland KST 70 is designed for professionals needing a robust and reliable cable entry solution for industrial and protected outdoor applications. Its primary benefit is providing a secure, IP65-rated seal for cables ranging from 30mm to 72mm in diameter, protecting sensitive equipment from dust and water ingress. A key consideration is its operating temperature range, which is limited to +35°C, making it unsuitable for environments with prolonged high temperatures. Key features include its durable construction, high sealing performance, and compliance with safety standards like the 750°C glow wire test.

FAQs
What is the primary purpose of the Hensel KST 70 cable gland?
Its primary purpose is to provide a secure, dust-tight, and water-resistant (IP65) entry point for cables into enclosures, protecting internal components from environmental factors.
What is the maximum and minimum cable diameter this gland can accommodate?
The gland can accommodate cable diameters ranging from a minimum of 30mm to a maximum of 72mm.
Can this cable gland be used in outdoor, exposed environments?
It is rated for protected outdoor use, meaning it should be shielded from direct, prolonged exposure to the elements. It is not designed for fully exposed weather conditions.
What is the significance of the 750°C glow wire test?
Meeting the 750°C glow wire test indicates that the material used in the gland has a certain level of resistance to heat and flame, contributing to fire safety in electrical installations.
What temperature range is the KST 70 rated for?
The operating temperature range for this cable gland is from -25°C to +35°C.
What size hole do I need to drill for installation?
You need to drill a hole with a diameter of 83mm for the KST 70 cable gland.
What wall thickness can the gland be mounted on?
The gland is designed for wall thicknesses ranging from 1.5mm up to 3mm.
Troubleshooting
Gland does not seal properly around the cable.
Ensure the cable diameter is within the 30-72mm range. Check that the internal sealing components are correctly seated and tighten the gland firmly.
Difficulty fitting the gland into the enclosure hole.
Verify that the enclosure hole is precisely 83mm in diameter and that the wall thickness is between 1.5mm and 3mm. Remove any burrs from the drilled hole.
Gland shows signs of degradation.
Inspect for physical damage or chemical exposure. If degradation is noted, replace the gland to maintain IP rating and safety.
Reduced sealing performance in wet conditions.
Ensure the gland is fully tightened and the cable is properly centered and gripped. Check for any damage to the sealing surfaces.

Setup, Compatibility & Care
Setup:
- Prepare the Enclosure: Drill an 83mm diameter hole in the mounting surface. Ensure the wall thickness is between 1.5mm and 3mm.
- Insert the Gland: Feed the cable through the gland. The gland itself is designed to fit snugly into the prepared 83mm opening.
- Tighten: Secure the gland according to the manufacturer's instructions, ensuring a tight fit against the enclosure wall.
- Seal the Cable: Adjust the gland's sealing mechanism to firmly grip the cable (diameter 30mm - 72mm), creating the IP65 seal.
Compatibility:
- The KST 70 is designed for cables with diameters ranging from 30mm to 72mm.
- It is suitable for enclosures with a wall thickness of 1.5mm to 3mm.
- Intended for indoor use or protected outdoor environments.
Care:
- Periodically inspect the gland for any signs of damage or wear.
- Clean the exterior with a damp cloth. Avoid using abrasive cleaners or solvents that could degrade the material.
- Ensure the seal remains tight around the cable; if loose, re-adjust according to instructions.
