WL
Wide Selection of Two-circuit Limit Switches
• A wide selection of models are available, including the overtrav-
el models with greater OT, lamp-equipped models for checking
operation, low-temperature and heat-resistant models, and mi-
croload models.
• Microload models are added to the product lineup.
• Meets EN/IEC standards (only Switches with ground terminals).
• Switches with ground terminals have the CE marking.

The overtravel model (-2N Series), fork lever lock model (WLCA32-41 to 44), horizontal plunger (WLSD@) model, heat-resistive model, low-temperature model, and lamp-equipped model cannot be used with the corrosion-proof model.
- Page 6 2. For external dimensions and other information, refer to pages 77 to 94. 3. One-side operation means that three operational directions can be selected electrically, according to the change in direction of the oper- ating plunger. Those models for which one-side operation is impossible can only operate on both sides. For details, see page 94.
- Page 7 For details, see page 94. The operational plunger is factory-set to both sides. 4. The fork lever lock is configured so that the dog pushes the lever to reverse the output and this reversed state is maintained even after the dog continues on.
