Screw Terminal Switches
* For high-sensitivity overtravel models.
Direct-wired Connector and Pre-wired Connector Switches
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.
Characteristics
Note: 1. The above figures are initial values.
2. The figures in parentheses for dielectric strength are for the
High-sensitivity Switches.
*1. The values are calculated at an operating temperature of +5°C to
+35°C, and an operating humidity of 40% to 70%RH. Contact
your OMRON sales representative for more detailed information
on other operating environments.
*2. Switches with Connectors: 1,500 V.
