* The WL-2H1100-K, WL-2H2100-K, and WL-2H4100-K correspond with each set model WLG[], the design of which was
   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.

Note: Please use sealling 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. 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.
