SMC’s auto switches for actuators and air grippers featuring magnetic sensing technology
SMC’s selection of auto switches for pneumatic actuators and cylinders, and air grippers use magnetic detection with a technology that relies on a magnetic ring built right into the piston. As the latter moves through the pneumatic cylinder or gripper, the magnet creates a magnetic field, which an externally mounted proximity sensor on the actuator picks up.
Our auto switches are perfect for applications that need to precisely track piston positions in cylinders or grippers as they provide accurate feedback and control for your automation systems.
Proximity sensors: solid state switches and reed switches
SMC divides its proximity sensors into two main categories:
- Solid state switches
- Reed sensor switches
SMC offers both types in standard versions as well as models with a handy two-colour indicator that visually shows the ideal operating position through distinct light signals. There are also specialised options available—such as heat-resistant or magnetic field resistant— along with a variety of detection settings. Moreover, multiple lead wire lengths are offered to suit different installation needs.
SMC's solid-state switches take functionality to the next level, with models that include two-colour indicators and built-in diagnostics for enhanced operational visibility. For demanding environments, water-resistant variants are also available— while still providing the clear two-colour status feedback.
Actuator position sensor
For applications requiring exceptional precision, SMC’s cylinder position sensors are an excellent choice. They function as proximity switches that continuously monitor and transmit the actuator’s exact stroke position through an analogue signal.
The actuator position sensor is typically employed for:
- Measuring variables like dimensions, tension, workpiece thickness, and screw-in depth
- Providing real-time monitoring of the actuator’s position
- Differentiating workpieces based on their length or width
Being compatible with IO-Link, SMC’s actuator position sensor allows sensors and actuators to communicate effortlessly, leading to better control and monitoring.
