Need to turn devices on and off in a flash? Power up your components with this solid-state relay from Sensata | Crydom. It mounts directly onto a PCB and lets you maximise space in your setup, thanks to its compact dimensions of 43.1 (L) x 7.6 (W) x 25.4mm (H). A rated load current of 20A means it works a treat in medium-duty applications. As this component works with light rather than moving parts, there's less wear and tear to keep maintenance to a minimum. An insulation resistance of one billion ohms means your device will remain isolated and protected from your power source, even if there's a sudden surge. You'll find relays like this one used in the medical equipment sector and the logistics industry.

• Thermally conductive epoxy encapsulation resists heat build-up for use in demanding operations
• Performs reliably in harsh conditions, thanks to a broad operating temperature range of -30°C to +80°C
• Light weight of 11g doesn't place strain on your PCB

This product turns devices on at lightning-fast speeds of 1ms and turns them off in 0.3ms to give you near-instant response times.
