Sensata | Crydom Solid-State Relay, PCB Mounting, 28mm Length - CN Series - CN240A05

Speed through switching tasks with this solid-state relay from Sensata | Crydom. It uses light-based signals to open and close its circuit for lightning-fast machine control. Wear is no match for this device, as it switches without moving parts. A snappy turn-on time of half a cycle kickstarts the unit straight into switching. As shown by its IP67 rating, the product is fully protected against dust and submersion in 1m of water for up to 30 minutes. Use a relay like this one in power distribution systems and automated assembly lines.

Features & Benefits

• Compact dimensions of just 28 (L) x 5 (W) x 15mm (H) to maximise space in your setup
• Low off-state leakage current of 4mA to minimise wasted power while not in use
• Plastic body provides effective insulation and resistance to wear
• Stands up to use in harsh environments, thanks to a wide operating temperature range between -20°C and +80°C

How do I install this relay into my system?

This unit plugs into a relay socket (720-3990), so you can fit it into your setup without special tools. You can also solder it directly to your PCB.
