• Coil voltage: 12V DC
• Contact material: AgNi
• Mounting type: PCB
• Design: Miniature electromagnetic

How to use

The relay is designed for direct soldering onto a printed circuit board. Ensure that the PCB layout matches the pin configuration of the relay to prevent short circuits or improper connections. When soldering, use appropriate heat management to avoid damaging the internal components. Once installed, connect the 12V DC control signal to the coil terminals and the load circuit to the contact terminals according to the wiring diagram of your specific application.

What to consider before purchase

• Verify that your control circuit provides a stable 12V DC supply.
• Check the maximum current and voltage ratings of your load against the relay specifications.
• Ensure the PCB layout is compatible with the physical pin spacing of the relay.
• Confirm the environmental conditions of the installation site are within the operating limits.

Usage recommendations

For optimal performance and longevity, ensure that the relay is protected from voltage spikes by using a flyback diode when driving the coil with inductive loads. Regularly inspect the connections for signs of oxidation or mechanical stress.
