MBK/FED/1/0/Ex-1 JOLA magnetic switch for pressureless operation

Description

The MBK/FED/1/0/Ex-1 JOLA magnetic switch for non-pressure applications is most commonly used in protection circuits for process automation purposes.

MBK ex-magnetic switches have a probe tube with an integrated reed contact. A magnet that has been brought close enough to the switch point mark on the probe tube of the Ex magnetic switch will trigger a reed contact.

It should be noted that the reed contact is not a toggle switch, but that the switch is only toggled when the magnet is applied.
