Visually confirm that sockets have power—the face lights up when they're connected. The rubber housing protects sockets from damage caused by drops and impact. They are not intended for use in wet or damp environments.

Check the status of a ground connection—a green light signals that connectors have power and are safely grounded. A red light indicates power only. The lights are visible from any angle for quick identification. A quarter turn locks connectors in place to remain secure in high-vibration applications and prevent accidental disconnection.

Visually confirm your connector is working properly. A green light means your connector has power, while yellow means it has signal. If either light is off, you'll know whether you need to inspect your signal or power source. Because these connectors thread tightly onto M12 connections, they won’t let in contaminants or come loose from vibration in rugged industrial environments. Their poles and keyways adhere to standard coding layouts, reducing the chance you’ll mismatch connectors. All have A coding, so they send signal and power to AC and DC sensors, actuators, motors, light curtains, and other devices. They’re also often used to connect equipment to IO Link controllers and in Profibus, DeviceNet, and other fieldbus systems.

PVC insulation means these connectors resist abrasion and work well in indoor general purpose applications. IP66K and IP67 rated when mated, all block out dust and water from high-pressure washdowns or brief submersion.

Connectors with 5 poles can send two signals. An additional white light lets you know the connector is carrying the second signal.

90° elbow connectors fit snugly against equipment, so they’re good for tight spaces.

Add caps to protect connectors and maintain their IP ratings when not in use.
