Before using the Remote Sensor, read this manual carefully.
During installation and operation, pay close attention to the safety aspect.
◆ Ensure the power is switched off during installation ormaintenance operations.
◆ Use a regulated power supply, e.g. switch-model type.
Simpler power supplies, such as a full-wave rectification type,will cause the permissible ripple rating to be exceed and may
cause malfunction.

Detector: Connects detector switches (max.8) and transmits thedetected signals to Transmitter.

Transmitter: Provides power for Detector, also passes detectedsignals from Detector to Output Sensor.

Output Sensor: Puts out detected signal to external controller, also
sends power for operating of Detector and Transmitter.

◆ Ensure correct connections by reference to the wiring diagram.

Wiring diagram(Note)(-) line of Transmitter and (-) line of Detectors should be connected together
with a resistor of 1-2kohm.
Please note that the cable length of an output sensor may not longer than10m. The CE marking verifies that our products comply with the requirements of EMC directive. The surge test to an output sensor is not carried out.
When using an output sensor with cable length longer than 10m, a measure
to protect the sensor from serge current should be taken.

X:center off-set(mm)Y:transmitting
distance(mm)◆ Total current consumption of detectors must not exceed the rated drive current.
Reduce the switches when the total current consumption exceeds the drive current.
◆ The drive current is dependent on the transmission distance between Transmitter andOutput Sensor the degree of off-set between them-refer to Transmitting area diagram.
