Magnetic Reed Switches

The FM Range from Fortress Interlocks are a series of non-contact magentic reed switches with Volt Free contacts that are availabile in different sizes which have identical footprints to other manufacturer's switches.

These magnetically operated safety switches provide the most economical method of safeguarding hazardous machinery and have been designed to work with safety relays that have a low inrush current on the switch input. 

Available in both ABS plastic or stainless steel housings for hygienic applications within the food, beverage and pharmaceutical industries. High temperature variants are also available upon request. 

Unlike other magnetic switches on the market, all safety switches within the FM range don't need 24 volts to operate.
