Characteristics
Note. The data given above are initial values.
*1. For the pin plunger models, the above values apply for use at the free
position, operating position, and total travel position. For the lever models,
they apply at the total travel position. Close or open circuit of the contact
is 1ms max.
*2. For testing conditions, consult your OMRON sales representative.
