Component Specifications

Definition
A connection head or cable gland is a critical industrial component used to terminate and secure electrical cables entering sensor probes and other equipment. It serves multiple functions: providing mechanical cable retention to prevent pull-out forces from damaging connections, creating an environmental seal against dust, moisture, and chemicals, and maintaining the integrity of electrical insulation. These components are engineered to withstand vibration, temperature variations, and corrosive conditions while ensuring reliable signal transmission in industrial sensing applications.
Working Principle
Cable glands work through mechanical compression and sealing mechanisms. When tightened, an internal compression nut or seal deforms radially against the cable jacket, creating a secure grip and environmental seal. Simultaneously, the gland body threads into the equipment housing, forming a secondary seal at the entry point. This dual-sealing action prevents cable movement, protects against ingress of contaminants, and maintains the equipment's IP (Ingress Protection) rating.
Materials
Typically constructed from brass, stainless steel (304/316), nickel-plated brass, or engineered plastics (PA, PBT). Sealing elements use nitrile rubber (NBR), silicone, Viton (FKM), or EPDM depending on chemical resistance requirements. Materials are selected based on corrosion resistance, temperature range (-40°C to +120°C), and compatibility with industrial environments.

Frequently Asked Questions

What is the difference between a cable gland and a regular connector?

Cable glands provide mechanical retention and environmental sealing where cables enter equipment enclosures, while connectors primarily facilitate electrical connections between cables or components without necessarily providing strain relief or ingress protection.

How do I select the right cable gland for my sensor probe?

Consider cable diameter, thread size matching your equipment, required IP rating, material compatibility with your environment (corrosive, high temperature), and any certifications needed (ATEX for hazardous areas). Always verify manufacturer specifications for exact compatibility.

Can cable glands be reused after installation?

Most industrial cable glands are designed for single use as the sealing elements deform during installation. Reuse may compromise the environmental seal. Always consult manufacturer guidelines for specific products.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
