This versatile tool is suitable for use in lighting, heating and motion-based equipment.

Features & Benefits

• Maximum turn-on and turn-off time of half a cycle for rapid-fire switching
• Performs reliably in extreme environments, thanks to a wide operating temperature range between -40°C and +80°C

How large is this SSR?

This small but mighty SSR has compact dimensions of 43.1 (L) x 10.2 (W) x 26.04mm (H), so it's a sure fit for a densely packed PCB.

How do SSRs compare to electromechanical relays?

The main difference is that SSRs don’t have any moving parts. This gives them a longer operational life, as they're subject to less wear and tear than electromechanical relays.
