Solenoid Coil Characteristics
Characteristics
Note: 1. Do not allow the load current to exceed the rated value.
2. The contact ON/OFF timing is not synchronized. Confirm
performance before application.
3. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The
contact surfaces will become rough once they have been
used and contact reliability for smaller loads may be
reduced.
*1. Malfunction within 1 ms.
*2. With no icing or condensation.
*3. The degree of protection from the front of the panel.
