Note: For details of The WL high-sensitivity, high-precision models, refer to Limit Switch WL-N/WL Datasheet (Cat. No. C151-E1).
 Note: 1. The above figures are for steady-state currents.
          2. Inductive loads have a power factor of 0.4 min. (AC) and a time constant of 7 ms max. (DC).
          3. A lamp load has an inrush current of 10 times the steady-state current.
          4. A motor load has an inrush current of 6 times the steady-state current.
          5. For PC loads, use the microload models.
