Industrial interlocks, also known as interlock sockets or switched interlocked sockets, are specialized electrical connectors designed to enhance electrical safety in industrial and commercial environments. These robust connectors also feature a unique interlocking mechanism that prevents accidental disconnection and ensures a secure power supply to critical equipment.

Typically, industrial interlocks are surface-mounted and housed in durable plastic or aluminum enclosures, providing protection against harsh conditions and accidental contact. They are commonly used in factories, workshops, and construction sites to power heavy-duty machinery, power tools, and other electrical equipment.

At RS Philippines, you’ll find a wide range of industrial interlocks and interlock sockets to meet the demands of various applications. Our selection includes top brands known for their reliability and safety features, ensuring you find the perfect solution for your needs.

## **How Industrial Interlocks Work**

Industrial interlocks provide a safe connection through a mechanical interlock. This design ensures safe operation by preventing actions such as the switch closing if the plug is not inserted, the extraction of the plug if the switch is closed, or the opening of the socket outlet cover if the switch is closed. Additionally, the [industrial power plug](https://ph.rs-online.com/web/c/connectors/mains-dc-power-connectors/industrial-power-connectors/) can't be withdrawn with the switch in the 'on' position, effectively prolonging contact life.

## **Types of Industrial Interlock Sockets**

Industrial interlock sockets are available in various configurations to suit different applications and safety requirements. Here are some of the types of interlock sockets designed to provide secure and reliable power connections in demanding environments:

### **Switched Interlocked Sockets**

Switched interlocked sockets feature an integrated switch that isolates the power supply before the plug can be removed. This ensures enhanced safety by preventing accidental disconnection while the equipment is energized. Also, these sockets are ideal for applications where preventing unexpected power interruptions is crucial. 

### **Unswitched Interlocked Sockets**

Unswitched interlocked sockets provide a secure connection without an integrated switch. At the same time, the interlocking mechanism prevents accidental removal of the plug while the socket is live, ensuring a continuous power supply. Additionally, these sockets are suitable for applications where switching is handled separately or not required.

### **Keyed Interlocked Sockets**

Keyed interlocked sockets incorporate a unique keying system that prevents the insertion of incompatible plugs. Because only the correct plug can be connected to the socket, this design prevents mismatched connections and potential hazards. Keyed interlocks are particularly useful in applications where different voltages or power requirements are present.

### **Waterproof Interlocked Sockets**

Waterproof interlocked sockets are designed for use in harsh environments where exposure to moisture or dust is a concern. Also, they feature sealed enclosures and waterproof connectors to protect the electrical connection from the elements. These sockets are commonly used in outdoor applications, construction sites, and washdown areas.

## **Materials of Industrial Interlock Sockets**

The housings of industrial interlocks are molded from a range of materials such as plastic, thermoplastic rubber, aluminum, or PBT (polybutylene terephthalate), ensuring they're insulated, strong, and durable. To further enhance their resilience, a continuous polyurethane gasket seals the connection between the lid and base, making the units splashproof or even watertight. This combination of rugged materials and sealing ensures reliable performance and protection even in challenging conditions.

## **Industrial Applications of Interlock Sockets**

The ability of industrial interlock sockets to prevent accidental disconnection and protect against electrical hazards makes them invaluable in these applications:

### **Manufacturing and Production**

Industrial interlocks are widely used in manufacturing and production facilities to power machinery, assembly lines, and other equipment. Because of their robust design and secure connections, they can ensure continuous operation and minimize downtime caused by accidental disconnections.

### **Construction and Outdoor Applications**

Interlock sockets are often employed in construction sites and outdoor settings where electrical connections are exposed to the elements. As mentioned, waterproof and dustproof interlocks provide reliable power even in harsh conditions, ensuring safety and preventing equipment damage.

### **Maintenance and Repair**

Industrial interlocks are also useful for maintenance and repair technicians, providing a safe and secure way to connect power tools and diagnostic equipment. What’s more, their ease of use and robust construction make them ideal for field service applications.

### **Energy and Utilities**

In the energy and utilities sector, industrial interlocks are used to connect power distribution equipment, ensuring a secure and reliable [power supply](https://ph.rs-online.com/web/c/power-supplies-transformers/power-supplies/). Plus, their ability to withstand harsh conditions makes them suitable for outdoor installations and power generation facilities.

### **Entertainment and Events**

Interlock sockets are commonly used in the entertainment industry to power stage lighting, sound systems, and other equipment. And because they prevent accidental disconnections, they can also help avoid disruptions in performances or events.

## **How to Choose the Right Industrial Interlocks**

Assess these factors to ensure that your chosen industrial interlocks meet your safety requirements, electrical specifications, and environmental conditions:

### **Current and Voltage Rating**

Choose industrial interlocks with current and voltage ratings that match the electrical requirements of your application. Remember, using interlocks with insufficient ratings can lead to overheating, damage, and potential safety hazards.

### **Ingress Protection (IP) Rating**

The IP rating indicates the level of protection the industrial interlock provides against dust and water ingress. As such, consider the environment where the interlock will be used and select an IP rating that offers adequate protection. For example, outdoor applications or washdown areas may require higher IP ratings to ensure reliable operation and prevent water damage.

### **Material and Durability**

Industrial interlocks are available in various materials, including rubber, plastic, and aluminum. Consider the durability requirements of your application and choose a material that can withstand the expected mechanical stress, impacts, and environmental conditions.

### **Switching Functionality**

Determine whether you need switched or unswitched interlocks. For example, switched interlocks provide an integrated switch for added safety, while unswitched interlocks offer a simpler solution where switching is handled separately.

### **Keying Options**

If you need to prevent the connection of incompatible plugs, consider keyed interlocks. As mentioned, keyed interlocks ensure that only the correct plug can be inserted.

### **Mounting Style**

Choose an interlock with a mounting style that suits your installation requirements. Typically, options include surface mounting, panel mounting, and DIN rail mounting.
