SW-11 Magnetic Switch

 Purchased quality high-power reed switches with higher current rating and longer service life in the international market.

 Electronics housing is made of aluminum alloy and designed with larger internal space for easy wiring.

 Chamber is made of 304 stainless steel for strong corrosion resistance.

 Passed SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety and Flameproof Enclosure explosion protection.

 With high Ingress Protection rating IP66/67.


  • SW-11 Magnetic Switch is designed with a quality high power reed switch as its core component and full aluminum alloy housing. It is explosion protection certified for Flameproof Enclosure (Ex d IIC T6 Gb) and Intrinsic Safety (Ex ia IIC T6 Ga), which both are the highest explosion protection rating reached so far amongst similar products in the market.


    The magnetic switch can be categorized by its output method as SPST type and SPDT type. By its application, it can be categorized as overflow or dry-run for liquid level alarm and protection.


  • As the measured fluid level rises and drops, the magnetic float rises and drops as well, and when the permanent magnetic steel within the magnetic float moves close to the switch, it stimulates the attached switches, triggering reed switch’s status to change, and providing a signal back to the control system to realize the liquid level control.


    The output of the switches can be configured with SPST or SPDT, and can be set as anti-overflow or anti-dry protection.
