Cable Connections
(1) Cable length
When using the unit connection cable, junction cable, and extension cable together, the sum of the
length for all type of cables must be 30 m or less. This limitation is applicable to each the transmitter
and receiver respectively. Since up to 3 SL-V units can be connected in series, up to 2 sets of series
connection cables are required. Two sets of the SL-VS10 (cable length :10 m) cables can be used. In
this case, the sum of the length of all type of cables, including the series connection cable, must be
50 m or less. This limitation is also applicable to each transmitter and receiver respectively.
• Cables must be within the lengths specified. Failure to follow this specification may cause
improper operation of safety function, and may cause dangerous situation.
• The series connection cable cannot be cut or extended. If the cable is cut or extended,
safety features may not operate properly. Do not allow this to happen as it is extremely dan-
gerous.
(2) Minimum cable bending radius : 5 mm
(3) Identification of connector cables
Cables can be identified by the colors of their connectors and their cable insulation.
1. Cable Insulation colors
Cables connected to the transmitter : Color of cable insulation in grey
Cables connected to the receiver : Color of cable insulation in black
2. Connector colors
PNP output type cables or series connection cables : Black connectors
NPN output type cables : Grey connectors
PNP output type cables and NPN output type cables cannot be used at the same time (mixed wiring is not
possible). One type of cable must be chosen based on the application.
Be sure to connect the unit connection cable for receiver to the SL-V receiver and the unit connection
cable for transmitter to the SL-V transmitter.
