How to Choose the Right Cable Gland
Kabelförskruvningar – jämförelse av plast, mässing, rostfritt och EMC
Cable glands are essential for sealing, strain relief, and EMC protection The choice depends on material, IP rating, temperature range, and environmental requirements. Here we review plastic cable glands, brass cable glands, stainless steel cable glands and EMC cable glands.
Plastic (Polyamide)
- IP Rating: IP66 - IP68
- Temperature range: -20 to +100 °C
- Advantages: Lightweight, cost-effective, chemical-resistant
- Limitation: Not suitable for heavy cables or extreme environments
- Typical industries: Telecom, building automation, panel builders
Brass (Nickel-Plated)
- IP Rating: IP68
- Temperature range: -20 to +100 °C
- Advantages: Industrial standard, robust, high sealing performance, good strain reli
- Limitation: Can corrode in highly aggressive environments
- Typical industries: Automation, energy, machine building
Stainless Steel (AISI 303/316)
- IP Rating: IP66 – IP69
- Temperature range: -20 to +100 °C
- Advantages: Hygienic, corrosion-resistant, durable
- Limitation: More expensive and heavier than plastic/brass
- Typical industries: Food, pharmaceutical, offshore, chemical industry
EMC Cable Glands (Brass/Stainless Steel)
- IP Rating: IP66 – IP69
- Advantages: Lightweight, insulating, low-cost
- Typical industries: Building, telecom
Comparison Table
Valet av kabelförskruvning påverkas av både miljökrav och applikation. Tabellen nedan jämför de vanligaste varianterna – plast, mässing, rostfritt stål och EMC – utifrån IP-klass, temperaturintervall, fördelar, begränsningar och typiska användningsområden.
| Material | IP class | Temperature range | Advantages | Limitations | Typical industries |
|---|---|---|---|---|---|
| Plastic (Polyamide) | IP66-IP68 | -20 to +100 °C | Lightweight, low-cost, chemical-resistant | Not for extreme environments | Telecom, building |
| Brass (Nickel-Pl.) | IP68 | -20 to +100 °C | Robust, high sealing, industrial standard | May corrode in aggressive environments | Automation, energy |
| Stainless steel | IP66–IP69 | -20 to +100 °C | Hygienic, corrosion-resistant, durable | More expensive, heavier | Food, offshore |
| EMC (Brass/Stainless) | IP66–IP69 | -20 to +100 °C | EMC protection, strain relief | Requires grounding | Telecom, medical technology |
Summary
- Plastic cable glands är kostnadseffektiva och kemikalieresistenta, men passar bäst i enklare miljöer.
- Mässingsförskruvningar är industristandard för automation och energi, men kan korrodera i aggressiva miljöer.
- Rostfria screw connections är förstahandsvalet i hygieniska och tuffa miljöer som livsmedel och offshore.
- EMC cable glands ger effektiv avskärmning mot störningar och används där känslig elektronik behöver skyddas.
