Magnetic Ferroresonant Stand-Alone Safety Interlock Switch

The MFS is idea for applications as a stand alone switch where magnetic and ferroresonant signals are required.

  • Tamper resistant
  • Direct switching of relays and contactors up to 2 A at 230 VAC
  • Compact size mounts easily on 1-in. square tubing
  • Use with safety monitoring relays in applications requiring a higher level of safety reliability
  • NEMA 4

Overview

CE_UL-CUS.jpg
  • Tamper resistant — the combination of magnetic and ferroresonant signals required to close the safety contacts makes the MFS very tamper resistant
  • Stand-alone — use for lower risk applications as a stand-alone safety switch allowing direct switching of relays and contactors up to 2 A at 230 VAC
  • MFS-11 provides a visible LED which illuminates green when the actuator is in range and contacts are closed
  • MFS-12 provides a dual color LED indicator. The LED illuminates green when the actuator is in range and the contacts are closed. The LED illuminates Red when the actuator is out of range and contacts are open.
  • Compact size — mounts easily on 1-in. square tubing
  • Use with safety monitoring relays in applications requiring a higher level of safety reliability
  • NEMA 4 enclosure enables water washdown cleaning
