Sensor & Actuator Cables

In the intricate world of industrial automation, seamless communication between sensors and actuators is essential. Sensor cables and actuator cables are the lifelines that transmit vital data and control signals, ensuring the smooth operation of equipment and machinery. At RS Singapore, we offer a comprehensive range of sensor actuator cables designed to withstand the rigours of demanding industrial environments.

What are Sensor Cables and Actuator Cables Used for?

Sensor cables transmit data and information from sensors, which detect changes in the environment, to a control system. Actuator cables, on the other hand, carry control signals from the control cable system to actuators, which are devices that initiate actions based on the received signals. Together, they form a vital link in the feedback loop of industrial automation.

These cables are often bundled together in cable harnesses or conduits to protect them from external factors like UV radiation, vibration, chemical exposure, abrasion, and moisture. They are essential components in applications such as robotics, manufacturing lines, and process control systems.

Actuator and Sensor Cable Construction

Given the harsh conditions in many industrial settings, sensor cables and actuator cables must be robust, flexible, and reliable. The outer sheaths are typically made of durable materials like PVC or PUR to resist abrasion and environmental factors. Meanwhile, sensor connectors are designed to be secure and tight-fitting, ensuring a reliable connection even under vibration.

Understanding IP Ratings for Sensor and Actuator Cables

Ingress Protection (IP) ratings indicate a cable's resistance to dust and moisture. Common IP ratings for sensor and actuator cables include:

IP65: Protection against dust ingress and water jets from any direction. Suitable for general industrial use.
IP66K: Enhanced protection against powerful water jets, making them ideal for applications with high-pressure cleaning requirements.
IP67: Protection against temporary immersion in water (up to 1 metre for 30 minutes). Suitable for outdoor and wet environments.
IP68: Protection against continuous immersion in water (conditions specified by the manufacturer). Ideal for underwater applications.
IP69K: Protection against high-temperature, high-pressure water jets and steam cleaning. Essential for applications in the food and beverage industry.

Sheath Material Options for Sensor and Actuator Cables

The choice of sheath material for sensor and actuator cables depends on the specific application and environmental conditions:

Nylon: Offers excellent abrasion resistance and flexibility, making it suitable for dynamic applications be it connecting proximity sensors or pressure sensors.
Polyurethane (PUR): Provides superior resistance to oils, chemicals, and abrasion, ideal for harsh industrial environments.
Polyvinyl Chloride (PVC): A cost-effective option with good general-purpose properties, suitable for indoor applications.
Polypropylene (PP): Offers good chemical resistance and electrical insulation.
Thermoplastic Elastomer (TPE): Provides flexibility and resistance to extreme temperatures.

Sensor and Actuator Cable Types

Sensor connectors can be straight or angled to ensure flexible, secure, and reliable connections across different applications. Popular sensor connector types also include:

**M8: **A compact connector often used in sensors and actuators with limited space.
**M12: **A larger connector commonly used for industrial Ethernet and fieldbus applications.

Sensor and Actuator Poles

Sensor and actuator cables come in various pole formats, with the most common being 3-pole, 4-pole, and 5-pole. The number of poles determines the number of connections and the type of signals the cable can transmit.

Sensor and Actuator Sizing

Sensor and actuator cable sizes are typically specified by their cross-sectional area (CSA), which influences the cable's current-carrying capacity and maximum transmission distance.
