Typical Application Details

Typical Applications

On presenting the actuator to the

switch, the high-intensity

electromagnetic field together with a

resonant frequency signal causes the

contacts to close. On removing the

actuator (opening the door) the safety

contacts open, isolating the machine.

The switch can not be overridden by

magnets, tools, etc.

Safety contact operating distance:

make 7mm, break 9mm

Auxiliary contact operating distance:

make 9mm, break 14mm

On hinged doors, install switch at the opening edge.

Where 2 switches are mounted adjacent, they should

be no closer than 25mm. Recommend a 2mm spacing

between switch and actuator.

The Ferrocode switch can

be used without a control

unit for low risk/low power

applications.

Six Ferrocode switches can be used with one control

unit for high risk applications. Connect the N.C.

contacts (black and white wires) in series and the N.O.

contacts (green and yellow wires) in parallel.

One Ferrocode switch

used with a control unit

provides a higher

integrity system.

Note: Removable guards using Non contact

switches may require two switches, one at either

side of the guard, or the use of a flap to prevent

initial lifting of the non-interlocked edge.
