Cable Gland/Electrical Connection: Thread Size M12 to M40

Component Specifications

Definition

A cable gland is a mechanical device designed to attach and secure the end of an electrical cable to equipment, providing strain relief and sealing against environmental factors such as dust, moisture, and chemicals. In sensing elements/probes, it ensures reliable electrical connections while protecting internal components from external contaminants and mechanical stress.

Working Principle

The cable gland works by compressing a sealing element (such as a rubber grommet or O-ring) around the cable as the gland is tightened, creating a watertight and dustproof seal. It also includes a locking mechanism (usually a threaded nut) that grips the cable's outer sheath to provide strain relief, preventing tension from being transferred to internal electrical connections.

Materials

Typically made from brass, stainless steel (e.g., 316L for corrosive environments), nickel-plated brass, or engineered plastics (e.g., polyamide/PA6.6). Sealing elements are often EPDM, neoprene, silicone, or PTFE for chemical resistance.

Frequently Asked Questions

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

A cable gland primarily provides sealing and strain relief at the cable entry point, while a connector facilitates electrical mating between cables or devices. Glands protect connections; connectors enable them.

How do I select the right cable gland for a sensing probe?

Consider cable diameter, environmental conditions (IP rating needed), material compatibility (e.g., stainless steel for corrosive areas), thread size matching the probe housing, and certifications like ATEX for hazardous zones.
