XCKML110

What type of device is this?

This is a metal-bodied limit switch from Schneider’s XC Standard range. It is designed for position detection and end-of-travel sensing in industrial machinery and mechanical systems.

How does the actuator work?

It uses a spring-return metal end plunger with linear movement. The switch is intended for a vertical approach in one direction, with actuation occurring on the end of the plunger.

What contact arrangement does it have?

The switch has 4 poles with a contact configuration of 2 x (1 NC + 1 NO). This gives two normally closed contacts and two normally open contacts in a snap-action arrangement.

Does it use snap-action contacts?

Yes. This model uses snap-action switching, which helps provide a fast and defined contact change during operation.

Does it have positive opening contacts?

Yes. The normally closed contacts include positive opening operation. For the Schneider XCKML110, the minimum force for positive opening is 60 N.

What electrical connection does it use?

It is fitted with screw-clamp terminals. The terminal capacity is 1 x 0.34 mm² up to 2 x 1.5 mm² conductors.

What cable entry arrangement does it use?

The switch body has 3 tapped cable entries for Pg 13.5 cable glands. It is intended for cable outer diameters from 9 mm to 12 mm.

What is the housing made from?

It has a metal construction with a Zamak body. This gives the unit a robust format for industrial environments where a metal enclosure is preferred.

What are the main dimensions?

The overall dimensions are 77 mm wide, 81 mm high, and 36 mm deep. The net weight is approximately 0.4 kg.

What level of environmental protection does it offer?

This switch is rated IP66 for ingress protection and IK05 for impact protection. It is also specified with shock resistance of 50 gn for 11 ms and vibration resistance of 25 gn from 10 to 500 Hz.

What temperature range can it operate in?

The operating ambient temperature range is -25°C to 70°C. The storage temperature range is -40°C to 70°C.

What electrical ratings should be checked before installation?

Key ratings include a conventional enclosed thermal current of 10 A AC, rated insulation voltage up to 500 V under IEC 60947-1, and rated impulse withstand voltage of 6 kV. As with any switch, the application load and switching duty should be matched to the device specification.

What switching speed and operating force does it require?

The minimum actuation speed is 0.01 m/min and the maximum actuation speed is 0.5 m/s. The minimum force for tripping is 15 N.

How accurate is the switching point over time?

The repeat accuracy is specified as 0.1 mm on the tripping points after 1 million operating cycles, making it a solid choice for repeatable mechanical position sensing.

What kind of applications is this switch commonly used in?

It is commonly used for machine position monitoring, travel limit detection, gate or guard position sensing, conveyor end-stop indication, and other industrial automation duties where a plunger-style mechanical limit switch is appropriate.

How is the switch mounted?

This model is mounted by the body. The fixed-body design makes it suitable for installations where the switch is secured directly to the machine frame or equipment structure.

What kind of durability is expected from this switch?

The mechanical durability is rated at 3,000,000 cycles. Electrical durability is rated up to 5,000,000 cycles under specified DC-13 duty conditions.
