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-CHS 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-CHS 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 units of the SL-CHS Series 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-CHS connected in series is 4 pairs or less and the total number of
SL-CHS beam axes is 192 or less. The response time of the SL-CHS 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 connection cable, remove the top edge connector cover, and then install the cable.
Do not remove the connector cover when not connecting the units in series.
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-
CHS 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-CHS 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.
