Looking to switch your circuit's loads in a snap? This Sensata | Crydom solid-state relay opens and closes its connections using light-based semiconductors, quickly responding to signals for speedy component control. By working without moving parts, it cuts the risk of damage from wear to keep switching for longer. The included cover has an IP20 rating, so it's touchproof and protected against objects larger than 12mm for safe handling. Thanks to a rapid-fire turn-on time of just 0.1ms, the device is ready to tackle tough switching tasks straight away. Look for relays like this one in food production and packing systems.

• Screws directly to a panel for simple and secure mounting
• Durable plastic and aluminium housing to stand up to impact and wear
• Compact measurements of 44.5 (L) x 30.9 (W) x 57.3mm (H) to maximise space on your panel
• Anti-rotation barriers prevent the unit from working loose

This relay comes with a front-facing LED indicator that lights up when it detects current, making it easy to check its connections at a glance.
