WARNING
Limit the length of transmitter and receiver cables to 30 meters (1181.1") or less. If the cable
length exceeds the limit, the SL-C may not operate normally and a serious accident, such as
an injury or death of a machine operator, may result. In addition, when bent or flexed, these
cables should be allowed a minimum bend radius of 5 mm (0.2").
3-5 Series Connection
2 or more sets of the SL-C can be connected by using a pair of dedicated series connection cables to form a light
curtain with a single set of output logic.
If any beam axis of any series-connected SL-C unit is blocked, the OSSD output (or FSD output) is turned OFF and
the machine can be stopped.
This function is valid only when the number of SL-C connected in series is 4 pairs or less and the total number of SL-
C beam axes is 192 or less. The response time of the SL-C Series is not affected by the series connection.
Use the series connection cables.
• SL-S0: Cable length 0.08 m (3.15")
• SL-S1: Cable length 0.15 m (5.91")
• SL-S2: Cable length 0.5 m (1.64 ft.)
• SL-S3: Cable length 3 m (9.84 ft.)
• SL-S4: Cable length 1 m (3.28 ft.)
• SL-S10: Cable length 10 m (32.79 ft.)
When installing a series connecStion cable, remove the top edge connector cover, and then install the cable.
WARNING
Use only the series connection cables provided by KEYENCE ( See 1-2-2 “Cables” ( ➮
page 1-3) for special cable types and relevant information). Otherwise, the SL-C may
not operate normally and serious harm, such as an injury or death of the machine
operator, may result. Synchronization cables must be shielded cables. Failure to use
shielded cable may result in significant harm the machine operator, including serious
injury or death. When connecting the SL-C units in a series configuration by using the
SL-S10, limit the number of the SL-S10 units to two or less, and the total length of the
cables including the series-connection cables to 43 m (141.08 ft.) or less.
