Need a reliable messenger for your microcontroller? Turn to this optocoupler terminal block from Wago. It sends electrical signals between two isolated circuits, while its insulation reduces the risk of voltage interference. This means there's less chance of crossed wires in your signal processing network. A red LED makes it a cinch to visually check its status with just a glance. Cage clamp technology ensures durable wire connections that resist vibration and shock. For versatility, this optocoupler accepts solid or stranded conductors ranging in size between 28 and 14AWG.

• IP20 rating means it's finger-safe and protected against tools and wires larger than 12mm
• Optional vertical or horizontal mounting on a DIN rail for versatility
• Ultra-light weight of 18.4g to put minimal strain on a rail

• Hospitals and medical centres
• Building technology
• Railway systems
• Food and beverage production

The component is a sure fit for busy setups, thanks to its compact dimensions of 91 (H) x 6 (W) x 56mm (D).
