Cable Connector for SRT2-[]D08S

XS8A-044[] (Cable Connector)

XS8B-0443 (Relay Socket)

Calculate the cable conductor size as explained below.
The following information is given on each sensor cable:
     Cable dia. (Number of conductors/Conductor dia.)
     Conductor size (mm²) = (Conductor dia./2)² x π x Number of conductors
Example: E3S-A
     4 dia. (18/0.12)
     Conductor size (mm²) = (0.12/2)² x 3.14 x 18 0.20
The conductor size is 0.2 mm². Therefore, use the XS8A-0442.
