MECHAN

Mechan - MS7 coded magnetic

The Magnasafe MS7 is a magnetically coded switch offering greater tamper resistance than standard magnetically operated switches. The units are fully encapsulated into resin filled ABS housings and the long switching distance makes the MS7 to misalignment and gate wear.

When the switch and the actuator are apart, the safety contacts are open and the auxiliary contacts are closed. Moving the actuator to within the operating range of the switch (target to target) closes the safety contacts and opens the auxiliary contacts. Using versions with 2 safety contacts in conjunction with a Duelco safety relay will produce a higher integrity safety system.

Mounting

The Magnasafe safety switches can approach each other from any angle.
The target on the printed face of the switch must be aligned.
Mount the switch on to the machine frame and the magnet on to the opening door.
Use the tamper proof screws provided.
Do not use the safety switch as a door stop.



Leave a minimum of 50mm between any adjacent door switch



Always try to mount the switch to non ferrous material.
Ferrous material will reduce the switching distance.

Do not mount the switch to the hinge of the door



SLIDING DOORS
EN 1088 provides some mounting suggestions, see example below.
When fixing the safety switch to a sliding door
A) ensure that when the door is opened
B) it is not easily accessible, helping prevent the system being overridden.
