Sensata | Crydom Solid-State Relay, 5A Current Rating, SCR Output - CX Series - CX240D5R

For reliable switching in your electrical system, choose this solid-state relay from Sensata | Crydom. The device works by converting electrical signals into optical ones before firing them at a photosensitive transistor, which in turn sends the transmissions to other components. A broad operating voltage range of 12 to 280V AC means it's suitable for use in a wide variety of low-power systems. You'll commonly find an SSR like this one used in multiplexers, home appliances and I/O subsystems.

• Broad operating temperature range between -30°C and +80°C for use in demanding conditions
• Light weight of 11g to place minimal strain on your equipment
• Through-hole terminal type for a strong connection to your PCB
• Thermally conductive epoxy encapsulation for resistance to heat and impact
• Load current range of 0.06 to 5A for use in low-power applications

What are the dimensions of this unit?

This unit has compact dimensions of 43.1 (L) x 7.6 (W) x 25.4mm (H), so it allows you to maximise packing space on your PCB.

For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.
