Power Relays, Over 2 Amps Procurement Notes

Verify that the specific suffix '2300' corresponds to the SPST-NO contact configuration and 12VDC coil variant. Confirm package compatibility with your PCB footprint, as the 40 series offers both plug-in and direct soldering options. Ensure voltage ratings align with your load requirements, as this model supports up to 400VAC. Check for RoHS3 certification if environmental compliance is mandatory for your assembly process.

Power Relays, Over 2 Amps Selection Notes

Select this component when a compact relay is required to switch higher currents than standard signal relays allow. The 12A rating makes it suitable for direct control of resistive loads or small motors where space is constrained. Consider the 650mW coil power consumption for battery-operated or low-power control systems. Compare against the 40.51.9.012.0000 variant to ensure the contact form matches your circuit logic needs.

Power Relays, Over 2 Amps Part Context

This part belongs to the Finder 40 Series, a line of miniature electromagnetic relays known for their small footprint and high reliability. The series is widely used in applications requiring robust switching capabilities in limited spaces.
