Ever needed to control something powerful—like a motor or set of lights—with just a small signal? That's where the Omron LY2-AC24 comes in, a compact general purpose relay that punches way above its size.
This DPDT relay handles serious work: 10A loads at 110VAC, powered by a 24VAC input that sips just 46mA at 60Hz or 53.8mA at 50Hz. Measuring a slim 35.6 x 21.6 x 27.9mm, it slips into the tightest enclosures without a fight. Rated for -25°C to +55°C, it won't flake out in your garage workshop or a stuffy control box. Plus, with 2,000VAC dielectric strength and approvals from UL, CSA, IEC, it's ready for real-world reliability.
Picture this: a low-voltage coil gets energized, creating a magnetic field that flips the internal lever. That closes or opens high-power contacts—simple, mechanical magic without fancy electronics. It's normally open or closed depending on your wiring, perfect for turning stuff on when triggered or keeping it off until needed. No semiconductors here, just proven electromechanical switching that lasts.
In home automation, wire it to flip your garage door or pool pump from a smart switch. Tinkerers love it for Arduino projects, controlling relays to drive solenoids or fans. Automakers use similar ones for ignition systems or accessories. Even in lighting setups, it switches banks of LEDs or halogens without buzzing or heat issues. I've swapped clunky old relays for these in custom PC builds to handle case fans or RGB strips—snug fit, zero drama.
The beauty? One relay can manage multiple circuits independently, or chain them for complex logic. Pair with a timer or sensor, and you've got automated plant watering or security lights that actually work.
Omron's been making these since 1933, so you know it's not some fly-by-night part. Compact design saves space in crowded panels, and the specs mean fewer failures over time. If you're into electronics, DIY automation, or just fixing stuff around the house, this 24VAC relay is your go-to for dependable power switching. Grab the LY2-AC24 and make your projects click—literally.
