GUIDE · CABLE GLANDS
How to Choose the Right Cable Gland
sealing, strain relief, and safety start with the right cable gland.
This guide will help you choose the right material, IP rating, and type of cable gland for your application and environment.
What Determines your Choice?
Base these four factors on finding the right cable gland.
Environment
Indoor, outdoor, washdown zone, or chemically aggressive environment?
- Moisture and water
- Chemicals
- Temperature
- UV light
Material
Choose materials based on environment, corrosion, and requirements.
- Plastic (Polyamide)
- Brass (Nickel-Plated)
- Stainless Steel (AISI 303/316)
- Special (ATEX)
IP Rating
How much dust and water the screw connection endure?
- IP66
- IP68
- IP69 / IP69K
Cable Type
Standard cable or shielded EMC cable?
- Unshielded cable
- Shielded cable (EMC)
- Armored cable
- Multi-conductor cable
Choose the Correct Type of Cable Gland
Here are the most common types and their typical uses.
Plastic
Corrosion-free and cost-effective for most standard installations.
Typical environments:
Real estate, telecom, automation
Brass
(nickel plated)
Robust and reliable solution for industrial environments.
Typical environments:
Machines, automation, energy
Stainless Steel
(AISI 303/316)
Corrosion-resistant and hygienic for demanding environments,
Typical environments:
Food, pharmaceuticals, offshore
EMC
Provides 360° EMC shielding and protects against electrical interference.
Typical environments:
Frequency converter, telecom, energy
ATEX
ATEX/Ex approved for use in explosive environments.
Typical environments:
Chemistry, refinery, offshore, process industry
Comparison of Materials and Properties
Overview to quickly compare the most common options.
| Material / Type | IP Rating | EMC | Corrosion | Temperature Range | Typical environment |
|---|---|---|---|---|---|
| Plastic (Polyamide) | IP66 – IP68 | No | Very good | -20 to +100 °C | Real estate, telecom, automation |
| Brass (Nickel-Plated) | IP68 | No | Good | -20 to +100 °C | Automation, energy, machinery |
| Stainless Steel (AISI 303/316) | IP66 – IP69K | No | Excellent | -60 to +200 °C | Food, medicine, offshore |
| EMC (brass / stainless steel) | IP66 – IP69K | Yes | Good – Excellent | -40 to +200 °C | Frequency converter, telecom, energy |
| ATEX (Ex-cable glands) | IP66 – IP68 | Optionally | Depends on material | -40 to +100 °C | Ex-zone, chemistry, offshore, process |

FAQ – Frequently asked questions about cable glands
Which cable gland is best for aggressive environments?
Stainless steel (AISI 316) with IP69K.
When are plastic cable glands sufficient?
In indoor environments without high mechanical stress.
Are EMC cable glands always necessary?
No, only where sensitive electronics are at risk of interference.
Do you need help choosing the right cable gland?
Are you unsure which cable gland your installation requires? We help you choose the right material, IP rating, thread and seal based on cable, environment and technical requirements.
