Limit Switch Connectors
Connectors (SC Series)
Cabtire cables and flexible tubes with various diameters are used to
connect machine tools and controllers with Limit Switches. To ensure
the watertightness of the edges of the conduits, use an SC Connector
that is suitable for the external diameter of cable and model of Limit
Switch.
Ordering Information
Connector for Cabtire Cable
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.
Simple Connector
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.

Dimensions and Structure (Unit: mm)
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.
Follow the instructions given under Conduits on page 4.
Note: Dimensions not shown in the above diagrams have a variation of ±0.4 mm.

Safety Precautions
Conduits
Connector for Cabtire Cable/Flexible Tube
G½, ½-14NPT
To connect a Limit Switch with a connector, insert a rubber ring first
and then a washer into the conduit inlet of the switch body, put a
rubber seal, washer, and nut in this order onto the tapered part of the
connector and tighten the nut securely. Then tighten the conduit inlet
with the connector to maintain high sealing capability. Apply sealing
tape to the edge of the connector on the conduit inlet side to increase
sealing capability.
The SC-1M to SC-5M are provided with an O-ring, and so the
rubber ring, conduit washer, and sealing tape are not required.
