Door Interrupt System with FYQLA1-140R-3 Logic Amplifier

Guided relays

The door interrupt system incorporates two force-guided safety relays that are
monitored for proper operation and generate a redundant output for application
use.

Input devices

Magnetic switches

The 50FY41 series hall effect door switches are a noncontact, magnetic actuation
system consisting of a sensor and a magnetically keyed actuator. The sensor
contains two hall-effect integrated circuits that are connected independently.
When exposed to this magnetic actuator and properly aligned, the sensor
responds with an output.

Ensure the alignment of the sensor and magnetic actuator are correct
for proper operation. A 10 mm (0.39 in) separation distance between
sensor and actuator will cause an OFF condition, independent of axial
offset distance.
Sensor cable length must not exceed 25 m (80 ft).
