Author    |    hongxiang_admin    |    September 11, 2023

In the ever-evolving world of robotics and automation, precision, reliability and safety are paramount. These industries require equipment that can continue to operate under demanding conditions. Cable glands play a key role in ensuring cables and wires remain safe, protected and functioning in these environments.

In this blog post, we explore the importance of cable glands in the robotics and automation industry and how they contribute to efficiency and safety in these high-tech fields.


Understanding the Robotics & Automation Industry

Before we delve into the role of cable glands, it’s crucial to understand the scope and importance of the robotics and automation industry.

Robotics encompasses the design, construction, operation, and use of robots. These machines are engineered to carry out tasks autonomously or semi-autonomously, often with precision and repeatability far beyond human capabilities. They find applications in various industries, including manufacturing, healthcare, logistics, and agriculture.

Automation, on the other hand, involves the use of control systems and technology to streamline and optimize processes. This can range from simple tasks like automatic door sensors to complex industrial automation systems in manufacturing plants.

Both robotics and automation have far-reaching implications for industries in terms of efficiency, productivity, and safety.

The Role of Cable Glands in Robotics & Automation

Cable glands, also known as cable connectors or cable fittings, are mechanical devices used to securely attach and seal cables or wires to equipment.

In the context of the robotics and automation industry, these components play several crucial roles:

Cable Protection

In the dynamic and often harsh environments of robotics and automation, cables are exposed to various hazards, including physical damage, moisture, dust, and chemicals. Cable glands provide a protective barrier that shields cables from these external elements, ensuring the longevity and reliability of the electrical connections.

Secure Cable Management

Robots and automated systems typically involve the movement of various components, including arms, tools, and conveyor belts. Cables and wires must move with these components without becoming tangled or damaged. Cable glands help secure cables in place, preventing them from snagging, getting caught, or becoming entangled.

Sealing Against Contaminants

The automation and robotics industry often operates in environments where contamination can compromise the integrity of electrical connections. Cable glands feature sealing mechanisms, such as O-rings or grommets, that create a tight seal, preventing the ingress of dust, dirt, liquids, or gases into cable entry points.

Ensuring Safety Compliance

In industrial automation, safety is a top priority. Cable glands play a role in ensuring compliance with safety standards by preventing accidental contact with live wires, reducing the risk of electrical shock, and minimizing the potential for short circuits or electrical fires.

Vibration and Strain Resistance

Industrial robots and automated machinery may generate vibrations and mechanical stresses during operation. Cable glands are designed to absorb and mitigate these vibrations, preventing cables from disconnecting or being damaged due to mechanical strain.

EMI and RFI Shielding

In some automation and robotic applications, electromagnetic interference (EMI) and radio-frequency interference (RFI) can be problematic. Specialized cable glands equipped with EMI/RFI shielding can help reduce interference, ensuring the reliability of sensitive electronic components.

Types of Cable Glands

The choice of cable gland depends on various factors, including the environment, the type of cable or wire, and the specific requirements of the application.

Here are some common types of cable glands used in the robotics and automation industry:

Standard Cable Glands

Standard Cable Glands

These are versatile and used in a wide range of applications. They provide basic protection against dust and moisture and are suitable for many indoor and outdoor environments.

Armored Cable Glands

Armored Cable Glands

These cable glands are designed for use with armored cables, which have a protective metal sheath. They provide enhanced protection against mechanical damage and are often used in rugged environments.

Hygienic Cable Glands

Hygienic Cable Glands

In applications where cleanliness and hygiene are critical, such as in the food and pharmaceutical industries, hygienic cable glands with smooth, easy-to-clean surfaces are used to prevent the buildup of contaminants.

Explosion-Proof Cable Glands

Explosion-Proof Cable Glands

In hazardous environments where the risk of explosion exists, explosion-proof cable glands are employed. They are designed to contain any explosion within the gland, preventing it from spreading to other areas.

EMI RFI Shielded Cable Glands

EMI/RFI Shielded Cable Glands

These cable glands are equipped with shielding materials to protect against electromagnetic and radio-frequency interference. They are commonly used in electronic and communication equipment.


Cable glands provide the protection, organization and security necessary for the cables and wires that drive and control advanced systems. As these industries continue to grow and evolve, cable gland technology continues to evolve, providing innovative solutions to meet the demands of increasingly complex and sophisticated robotics and automation systems.

Selecting the correct cable gland for a specific application is critical to ensuring optimum performance, safety and reliability. Manufacturers and engineers in robotics and automation must carefully consider environmental factors, cable types and their system’s specific needs when selecting cable glands.
