5A 250VAC Mounting PCB Miniature Power Relay With Sensitive Coil

 

In different external environments, the impact on the relay is not the same. For example, high temperature / humidity / dust / gas / vibration impact, etc., so select the appropriate product according to the actual environmental conditions.
1, The temperature of the relay directly affects the life of the relay. The higher the temperature, the shorter life. The general use of the ambient temperature ot relay is 70℃,please refer to the product recommended temperature when using.
2, Humidity generally affects the contact performance of the relay, which has the greatest impact on the circuit of the tiny current. The wet environment accelerates the oxidation of the contact and the internal metal parts, creating a layer of oxide on the contacts to increase the contact resistance. Under the normal conditions, select the sealed relay when the humidity is greater than 90%.
3, Dust, gas (including S, NO, HCl, etc.) and more serious environment generally affect the contact performance of the relay. Dust, or gases with S and Ag generated Ag2S attached to the contact surface, resulting in increased contact resistance. Select sealed relay in the case of bad environment.
4, The environment with serious vibration and impact will affect the reliability of the relay, prone to malfunction or coil disconnection. In general, the vibration resistance of relay is 55HZ (international standard), automotive relay is larger, about 400HZ or 500HZ. So it should give priority to the use of automotive relays if it is used for the equipment with greater impact of vibration
