changed in April 2019.
Please inquire if you desire a single-item head manufactured before the design change. On products that underwent the
design change in April 2019, the front of the switch box cover at the bottom front has a protruding shape, and on earlier
products has a depressed shape.

The SC-6 and SC-P2 models are made of resin. If higher sealing performance is required, use one of SC-1M to SC-5M, which have metal connectors.

Operating characteristics

Note: With WLCAL4-N, WLCAL4-LD-N and WLCAL4-LE-N the actuator's tare is large, so depending on the installation
direction, they may not be properly reset. Always install so that the actuator is facing downwards.
* This is the value when the rod length is 380 mm.
