The 6AV6881-0AE10-0CB0 is a 3-pole female connector (socket) for SIMATIC HMI devices, with 3.5mm pitch and straight (180°) orientation. It uses traditional screw terminals and accepts 0.14–1.5mm² conductors. The green housing distinguishes it from other variants in the series. Manufactured by Weidmüller for Siemens.

6AV6881-0AE10-0CB0 vs 6AV6881-0HE20-0AA0 — how do they differ?

Three key differences: pin count (3-pole vs 8-pole), terminal type (screw vs spring-clamp), and color (green vs black). The 0AE10 is a simpler connector for basic 3-wire HMI connections with traditional screw-down wiring. The 0HE20 handles 8 signals with tool-free spring-clamp wiring in a more compact 2-row layout. Choose based on your signal count and preferred wiring method — they are not interchangeable.

Why screw terminals instead of spring-clamp?

Screw terminals provide a traditional, visually verifiable connection for applications where the connector is wired once and rarely changed. They accept the same 0.14–1.5mm² conductor range. If you are doing high-volume panel wiring with frequent re-termination, the spring-clamp variant (6AV6881-0HE20-0AA0) offers faster turnaround with no tools required.

Compatibility notes

This is the original equipment socket for compatible SIMATIC HMI panels requiring a 3-pole, 3.5mm pitch connection. Verify your device pinout before ordering — substituting an 8-pole connector will not fit a 3-pole header. Supplied in packs of 10 pieces without ejector.
