Question
What connectors should be used for Limit Switches?
Answer
SC-series Limit Switch Connectors are available. Select the Connector according to the size of the conduit port and the external diameter of the cable to be used.

Note:
1.Use SC-21 to SC-25 together with the rubber ring and conduit washer for the SC-P2.
2.It is necessary to use sealing tape with SC Connectors. SC-1M to SC-5M, however, are provided with an O-ring (NBR) and therefore sealing tape is not necessary to ensure a proper seal.

Connectors for Cabtire Cable
SC-P2 accessories and sealing tape must be used together with models without an O-ring in order to prevent ingress of oil or water.

Note:The casings for SC-P2, -P3 and -6 are made of resin. If more sealing capability is required, use one of SC-1M to SC-5M, which have metal casings.
Models marked with an asterisk (*) however, can only be used with resin connectors.
