The Telemecanique XCKD series is another range of modular limit switches from Schneider Electric(formerly Telemecanique), designed for industrial applications where durability, high performance, and flexibility are needed. The XCKD switches are similar to the XCKP series but come with a metal housing, offering enhanced protection in more demanding environments.

Key Features of Telemecanique XCKD Limit Switches:

1. Metal Housing:
   • The metal housing provides superior strength and robustness compared to plastic housing switches. This makes the XCKD series particularly suitable for environments where the switch may be exposed to harsh conditions, such as heavy impacts, vibration, high temperatures, and exposure to certain chemicals or oils.
2. Modular Design:
   • Like the XCKP series, the XCKD switches feature a modular design, which allows for customization by selecting different actuator heads and components. This versatility makes it easier to tailor the switch to specific machine requirements, improving ease of installation and use.
3. Actuator Types:
   • The XCKD series offers a wide range of actuator options that include:
     • Roller plungers
     • Roller arms
     • Levers (both long and short)
     • Wide plungers
   • These actuator options enable precise detection of mechanical movements and positions.
4. Durability:
   • The XCKD series is built to last with the ability to handle up to 30 million mechanical operations, ensuring longevity even in demanding applications.
5. Electrical Ratings:
   • The XCKD limit switches can handle a variety of electrical ratings, suitable for both AC and DC circuits. The contact configuration can be selected based on the required control system.
6. Environmental Protection:
   • The IP66 and IP67 ratings provide protection against dust and water, allowing the XCKD switches to perform well in outdoor and industrial environments where exposure to moisture, dirt, and other contaminants is common.
   • Some models also provide higher degrees of protection from corrosion or other environmental challenges.
7. Wide Temperature Range:
   • The XCKD switches can function in extreme temperature conditions, typically from -25°C to +70°C, making them versatile for use in outdoor, automotive, or heavy-duty industrial environments.
8. Compact and Versatile:
   • Despite the metal housing, the switches are still compact and easy to integrate into existing control systems. They can be used in tight spaces or areas where durability is critical.

Typical Applications:

• Automated machinery: Used for position detection and limiting movements in machines and robots.
• Heavy industrial environments: Withstanding the rigors of factory floors, especially in environments with mechanical wear and tear.
• Conveyor systems: Ensuring precise control of the conveyor belts and detecting overtravel.
• Automotive applications: For position sensing in automotive machinery.
• Safety-critical environments: Where high durability and environmental protection are essential.

Example Models in the XCKD Series:

• XCKD2102P16: This model typically comes with a roller plunger actuator and is designed for general-purpose use in industrial environments.
• XCKD21H2P16: This version may feature a longer lever actuator, suitable for applications requiring greater distance in the mechanical movement.

Advantages of XCKD Over XCKP:

• Increased Mechanical Protection: The metal housing makes it more resilient to impact, vibration, and extreme operating conditions.
• Better Resistance to Harsh Chemicals and High Temperatures: The robust metal construction ensures that the switch can survive in environments where the plastic housing might fail.
