5 - 8 E3NW-CCL CC-Link Digital Sensor Communications Unit User’s Manual (E431)
• Connector configuration: RJ45 8-pin modular connector (ISO 8877 standard)
• Terminal Arrangement
Connect the Unit power supply (24 VDC).
• Connector type: Two-pin spring cage connector with lock screws
• Applicable ferrule diameter: 0.25 to 0.5 mm

(AWG24 to AWG20) (Using ferrules with insulating
sleeves)
Refer to 4-3-3 Connecting the Unit Power Supply for the recommended ferrules.
Contact
resistance
Initial contact resistance: 50
m
Ω
max. The increase in
contact resistance after each
environmental test is
performed must be no more
than 25 m
Ω
.
Perform measurements with a resistance measurement current
of 1 mA and open voltage of 20 mV using the 4-terminal
method. (This assumes that applicable OMRON connectors
are used and includes contact bulk resistance.)
