Product Description

Product Description

ATTENTIONS

This product is flux proofed type, so it is recommended to store this product for less than 6 months, and pay attention to the storage

environment.

To ensure the performance of the relay, please prevent the product from falling, collision and unnecessary impact.

Applying no diode to this relay. The life expectancy will be lower when a diode is used. To use a varistor

(ZNR) could absorb the coil surge of relay that is recommended.
