T78 small electromagnetic relay produced by our company is widely used as automobile relay, so how to install the T78 automobile relay? What should be paid attention to when installing the T78 automobile relay? Here is a brief introduction to the installation method of T78 automobile relay
1. Installation direction
If the installation direction is the same as the shock resistance direction of the relay, the performance of the relay can be brought into full play. It is suggested that making the direction of impact perpendicular to the direction of contact and armature movement can effectively improve the vibration and impact resistance of normally closed contacts in non excitation state. During installation, the contact axis of the relay is parallel to the ground, which can avoid contact splash and carbonization falling on the contact surface and improve the contact reliability. Multiple sets of relays shall avoid small load contacts being located below large load contacts.
2. Do not install too close
When multiple relays are installed close to each other, it will cause abnormal heating, which is generally recommended as 2mm spacing. The close installation of polarity or magnetic holding relay will affect the operating voltage.
3. The relay shall be installed in the housing. The housing shall not be removed and installed first. In order to prevent looseness, damage and deformation, please use spring washer. The tightening torque shall be within the range of 0.5 ~ 70N · M.
4. The insertion strength of plug-in relay is recommended to be 40-70n.
5. Products meeting the same load requirements have different overall dimensions. According to the allowable installation space, products with low height or small installation area can be selected.
With the development of relay technology, the volume and service life of automobile relay are getting smaller and longer. T78 automobile relay is loved by more and more customers.
The correct installation of automobile relay can protect the relay well, make the relay play the maximum service life, and keep the sensitivity of the relay.
