KEYENCE SL-V Series - Manual (Page 3)

3 SL-V-IM-E
(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 dangerous.
(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 for Transmitter : Cable insulation in grey
Cables for Receiver : Cable insulation in black
2. Connector colors
PNP output type cables : Black connectors
NPN output type cables : Grey connectors
Series connection cables : Black connectors
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.
 Simple function type
 Multi-function type
When the muting bank function is used, the pin assignment changes as follows.
Pink: muting bank input 3, purple: muting bank input 1, red/black: muting bank input 2

1 The unit connection cable for transmitter (cable insulation is grey) must be connected to the transmitter as shown below. Sim-
ilarly, the unit connection cable for receiver (cable insulation is black) must be connected to the receiver as shown below.
Recommended tightening torque : 0.3 N·m
Minimum cable bending radius : 5 mm

• Do not remove the grey gasket installed on the connector. This gasket is necessary to ful-
fill the requirement of IP65 or IP67.
• Connect the unit connection cable to the connector receptacle on the lower part of the SL-
V. Removing the connector cover on the upper part of the SL-V and connecting the unit
connection cable may result in an SL-V failure.
2 For the SL-VHM, ferrite core is not required. However, for the SL-VF, SL-VH, SL-VL, or SL-VLM, one
ferrite core must be put on the SL-V unit connection cable for the transmitter. On the other hand, for
the SL-VFM, two ferrite core must be put on the SL-V unit connection cable for the receiver.
*1 The side where the connector cover has already been installed at shipment is the top side.
Beam center-line : An optical path joining the optical center of the emitting element on the transmit-
ter to the optical center of the corresponding receiving element on the receiver.
the SL-V must be installed so that the beam center-line mark on the transmitter
and that on the receiver face one another and are located at the same height.
Detection height : The height from the top beam center-line to the bottom beam center-line (length).
Protection height
: An object approaching the detection zone from the top of the detection height is first
detected at point A, which is the distance of the detection capability from the top of the
detection height. The equivalent position on the bottom is called point B. The height from
the top edge of the specified detection capability that exists at point A to the bottom edge
of the specified detection capability that exists at point B is called a "protection height".
The following calculation formula can be defined:
Protection height = "Detection height" + 2 x "the specified detection capability"–"beam axis diameter".
* Refer to the following diagram for an explanation of beam center-line, detection height and protection height.
