For a reliable way to switch power to your industrial devices, turn to this solid-state relay from Sensata | Crydom. Its semiconductors turn your equipment on and off using light-based signals, so it works without moving parts. This minimises the risk of mechanical wear for long-lasting performance. You can mount the relay onto a PCB in a jiffy by soldering its pins in place. A rated load current of 3A means it's just the thing for low-power machinery. SSRs like this one are commonly found in fluid management systems and the manufacturing industry.

• Quick turn-on time of 1ms for rapid-fire switching
• Thermally conductive epoxy encapsulation for effective heat dissipation
• Safe for use in harsh environments, thanks to a wide operating temperature range between -10°C and +80°C
• Light weight of 11g puts minimal strain on your setup

This product comes with pin labels on its front face, making it a doddle to tell where your connections go for hassle-free wiring.
