Check both the coil and contact specifications
Relays differ in how they are driven and what they can switch. This collection contains individual relays and related switching products. Use the product drawing and ratings to identify the exact device rather than relying on pin count alone.
- Match coil voltage and current to the drive circuit.
- Identify normally open, normally closed and common contacts.
- Check load ratings for AC or DC operation and the actual load type.
- Confirm pin spacing, footprint and mounting dimensions.
If you need a ready-made control board, compare relay modules. Browse power supplies and connectors for related components. An individual relay may require an appropriate driver and suppression components; verify the design rather than connecting its coil directly to a microcontroller pin. Hazardous-voltage switching requires suitable protection and installation.
