ABB has released a 1,200-unit line of key interlock switches and non-contact switches
ABB Jokab Safety has released a 1,200-unit line of key interlock switches and non-contact switches. The MKey Interlock Switches provide position interlock detection for moving guards, and are designed to fit the leading edge of sliding, hinged or lift-off machine guards. They are available in two holding strength versions, 12N and 40N, and have several actuator types for differing applications. The Sense Coded Non-Contact Switches, designed to interlock hinged, sliding and removable guards doors, are targeted to operate in environments that require the highest level of safety.
MKey Switches are also available with a locking function for moving guards, allowing the switch to be locked in the protective position, preventing unwanted access to machinery until dangerous operations have ceased.
Sense Switches are resistant to both dirt and water, and have no dust collecting cavities. The magnetic switches have a long working life since no mechanical contact is necessary for operation. The sensing distance of Sense Switches is up to 14 mm and has a high tolerance to misalignment.
