Ethernet (EtherNet/IP, PLC Link, No-protocol, or PROFINET) Connection
FQ2-S1 FQ2-S2
Ethernet cable can be used to connect to a variety of networks in order to input measurement
triggers and communication commands, and to output measurement results (judgement results,
measured values). Measurement triggers can also be input from a parallel connection. The data
link function for each network (excluding no-protocol networks) can be used to periodically
transfer data between the sensor and external devices.

*1: A special Ethernet cable is used to connect to the sensor.
RS-232C Serial Connection
FQ2-S3 FQ2-S4
An RS-232C Interface Sensor Data Unit can be connected to the Sensor by RS-232C cable to
enable input of measurement triggers and communication commands, and output of measurement
results (judgement results, measured values). Measurement triggers can also be input from a parallel
connection.
Basic configuration
FQ2-S/CH Series
Special Ethernet Cable
(RJ45/M12)
*2: A parallel cable (FQ-SDU2 special-purpose cable) can be used to connect to external devices from the Sensor Data Unit.
In this case, an ACK signal can be used as an additional output signal.
