Chapter 3 Installation
Switch Orientation
Can be used in all mounting orientations.
Actuator Orientation
The actuator can approach the switch from three directions (Figure 1).
Figure 1 - Three Directions of Approach
The flexible actuator can move in multiple axes to accommodate guard door
misalignment (Figure 2
). For optimal performance, verify that the locking bolt
can enter and withdraw from the tongue actuator without binding. A
separately mounted door latch is recommended to avoid door misalignment.
Figure 2 - Actuator Function
Pair Proximity
If a pair of 440G-MZ safety switches are mounted too close to one another, the
two electromagnetic fields interact causing crosstalk, which can result in
nuisance faults and false operation.
A minimum of 100 mm (3.94 in.) must separate a pair of switches to help
achieve correct operation (Figure 3 on page 14
).

IMPORTANT If the minimum separation distance is not observed, the electromagnetic fields
interact causing crosstalk. Crosstalk can result in nuisance faults and false
operation.
