Limit Switch Sensors
A limit switch is an electromechanical device that detects the position or movement of an object by physical…
How do limit switch sensors work?
- Physical contact: The moving object touches the sensor actuator.
- Switch activation: This contact triggers the sensor, changing the state of the switch.
- Electrical signal: The circuit change sends an electrical signal.
- Control or safety: This signal can stop a machine, indicate a change of position or initiate an automatic action.
These devices are widely used in industry to:
- Control machines
- Control automatic doors
- Control lifting systems.
They ensure the safety, precision, and efficiency of industrial operations while guaranteeing a high level of reliability. Their advantages? They are robust enough to withstand demanding industrial environments (dust, vibration, humidity, etc.). These products are very popular because they react instantly to physical movement, without the need for complex technology. They are both energy-efficient and easy to install. You'll find them in switchgear and electrical panels to protect contacts or control modular equipment, like those from Schneider Electric.
Types of limit switch sensors
The limit switch sensor ensures that machines or objects reach a precise position in automated systems and safety devices. The actuator, the central element, makes contact with the object or machine to activate or deactivate an electrical circuit. This mechanism detects end positions, triggering actions such as stopping a machine or moving on to the next stage in an industrial process.
Different types of actuator:
- Roller plunger: Knob with a roller to reduce wear and facilitate movement.
- Roller lever: Articulated arm with roller for precise activation.
- Flexible spring-loaded rod: Flexible actuator that adapts to variations in movement.
- Metal rod: Rigid rod for a firm, precise response.
These actuators allow sensors to adapt to a variety of configurations and technical requirements, from production lines to safety systems.
Main types of sensor:
- Direct-contact mechanical sensors: With pushbuttons or roller levers, activated by physical movement.
- Non-contact sensors: For environments requiring detection without physical interaction.
- Ultrasonic and magnetic sensors: Used in complex or difficult-to-access installations.
A closer look at the different types of sensor
Roller plunger
The roller plunger sensor detects the end position of a moving object, controlling or stopping a process. Its roller-equipped lever rolls in contact with the object, activating internal contacts to open or close an electrical circuit. A return spring repositions the roller and lever, ensuring accurate, repeated detection.
Recommended telemechanical models:
- XCMD2102L1: Robust metal housing, ideal for harsh industrial environments.
- XCKM102H29: Body material: Zamak metal, resistant and IP66 protected against dust and humidity.
- XCKD2145P16: Rotating head, IP66/IP67 protection for extreme conditions.
Roller lever
The roller lever extends the plunger and can be adjusted to extend the angle of attack.
Recommended roller lever limit switch sensors from the Télémécanique range:
