Proximity sensors

Proximity sensors are sensors that detect the magnetic field of the piston magnet via a magnetic field or reed contact. They are used for binary feedback of the piston position of pneumatic drives. Mounted at the desired switching position in the slot of the cylinder, proximity sensors output a standardized 24 V switching signal when the piston magnetic field is detected.

Proximity sensors from Festo: Special solutions for special requirements

Proximity sensors from Festo are tailored and optimized for Festo's drives. They detect the magnetic field of permanent magnets installed in the piston of the cylinder and thus indirectly indicate the position of the piston rod. The range includes proximity sensors for standard applications and solutions for special applications.

Proximity sensors for T-slot

Proximity sensors for T-slots are available as electronic versions and with reed contact. In addition to standard solutions, the range of switches also offers variants for almost all industrial segments, such as welding field resistant, 230 V, high temperature 120 °C, low temperature -40 °C, food-safe, acid-resistant, cooling lubricant-resistant, outdoor applications, ATEX, 5 V supply voltage.

FAQs - frequently asked questions explained easily

What are proximity sensors?

Proximity sensors are sensors that detect the magnetic field of the piston magnet via a magnetic field or reed contact. They are mounted at the desired switching position in the T-slot or circumferential slot of the cylinder and output a standardized 24 V switching signal when the piston magnetic field is detected.

What are proximity sensors used for?

A pneumatic cylinder is a component of a pneumatic drive system that creates a motion with compressed air as the medium. Proximity sensors are used for binary feedback of the piston position of pneumatic drives.
