binder Revises M8 Connector Standard With 12-Pin Design
A revised DIN EN IEC 61076-2-104 specification now includes C-coding for binder's 12-pin M8 connector interface.
Updated on Nov. 6, 2026 in Robotics
binder's 12-pin M8-C connector design, first introduced in 2020 as proprietary coding, has been incorporated into the revised DIN EN IEC 61076-2-104 standard. The update adds C-coding to the specification for the interface, which has been used in industrial applications since 2020.
Why it matters
The customer needed more signals than eight-pin M8 connectors allowed but could not enlarge the existing connector size. The standardization is expected to give equipment designers greater confidence when specifying components and planning future systems.
The 12-pin M8-C connectors are rated at 1A and 30V or 32V depending on version, with a 500V rated impulse voltage and IP67 protection when mated and secured. The source does not address how widely the design will be adopted beyond binder's product line.
The players
binder
binder is a German manufacturer of electrical connectors and sensor-actuator systems that developed the 12-pin M8-C interface.
The details
binder developed the 12-pin design after a request from a manufacturer of length measuring systems, using five smaller coding keys instead of a single larger one. The connector bodies are assembled by hand with the 12 gold-plated brass or bronze contacts, each measuring 0.5mm in diameter.
Timeline
2020: binder introduced the 12-pin M8 design as proprietary coding.
Since 2020: The 12-pin M8-C interface has been used in industrial applications.
Tech Race
The update to DIN EN IEC 61076-2-104 places binder's 12-pin M8-C design within the formal international standard for M8 connectors. It moves a previously proprietary coding into a recognized specification that competing manufacturers can reference.
Engineers specifying sensor and actuator systems can now reference a standardized 12-pin M8 interface for applications needing more than eight signals. The standard gives designers a common specification to plan future equipment around.
The takeaway
Standardized connector specifications reduce uncertainty for equipment designers choosing components for multi-signal industrial applications. Designers should check whether their target equipment requires the 12-pin M8-C coding.
