Power your electric circuit up in a flash using this solid-state relay from Sensata | Crydom. It works by switching an electrical signal to an optical one, so it does away with moving parts to minimise wear. Thanks to its rated load current of 50A, it's up to the challenge of controlling your high-power systems. Its housing features robust anti-rotation barriers that help to keep a firm hold in vibrating conditions. You can use this SSR in robotics and medical devices.

• Built-in LED indicators for ease of status monitoring
• Compact dimensions of 44.5 (L) x 30.9 (W) x 57.3mm (H) to save space in your setup
• Tough aluminium baseplate for resistance to wear and corrosion

This SSR has a speedy turn-on time of 20ms and a turn-off time of 30ms, so you can rest assured it gives you fast results.

It has an MTBF of more than 11 million hours at +40°C and over seven million hours at +60°C, so it's built to last.
