Product Information
Original Instructions
Magnetically Coded Non-contact Switch (MC2)
Catalog Numbers 440N-Z21W1PA, 440N-Z21W1PB, 440N-Z21W1PH
Wiring
Recommended Mating Cable
The standard cable lengths are 2 m, 5 m, and 10 m. Use catalog number 889D-F8AB-2 [2 m (6.5 ft)] for the
standard length. Replace the 2 with 5 [5 m (16.4 ft)] or 10 [10 m (32.8 ft)] for other standard cable lengths.
Status/Diagnostic Indicator
Mounting Information
Use nonremovable screws, bolts, or nuts to mount the switch and actuator. Do not over torque the
mounting hardware. It is recommended to use M3 screws and washers throughout.
Maximum torque is 1 N•m (8.86 in•lb). Use nonmagnetic mounting hardware.
Position the switch and actuator so they are aligned with each other.
Mounting for Maximum Misalignment
Mount the sensor to the fixed part of the guard and the actuator to the movable section. Keep the sensor
and actuator within the sensing range detailed as shown in Figure 3 on page 2
.
Minimum distance between sensors is 50 mm (1.97 in.).

ATTENTION: Read this document and the documents that are listed in
Additional Resources
on page 2 about installation, configuration, and
operation of this equipment before you install. Users are required to
familiarize themselves with installation and connection instructions and
requirements of all applicable codes, laws, and standards.In accordance with
applicable codes of practice, suitably trained personnel are required to
implement installation, adjustments, service initiation, use, assembly,
disassembly, and maintenance. If this equipment is used in a manner that the
manufacturer does not specify, the protection that is provided by the
equipment may be impaired.
ATTENTION: The presence of spare actuators can compromise the integrity
of safety systems. Personal injury or death, property damage, or economic
loss can result. Appropriate management controls, working procedures, and
alternative protective measures should be introduced to control their use and
availability.
WAR NI NG: Do not defeat, tamper, remove, or bypass this unit. Severe injury to
personnel could result.

± 4 mm (0.16 in.)
To prevent damage, it is recommended that a 2 mm (0.08 in.)
gap be maintained between the actuator and sensor.
