Technical Description: ifm electronic EVC811
The ifm electronic EVC811 is a high-quality Y-connection cable (splitter) designed for the efficient distribution of signals and power in industrial automation systems. It allows for the connection of two sensors or actuators to a single M12 port on an I/O module or junction box. This is particularly useful in applications where space on the I/O block is limited or where synchronized signals are required from two different points on a machine.
Design and Material Quality
The EVC811 features one M12 male connector branching into two M12 female connectors via a short, robust cable section. The cable jacket is made of PUR (Polyurethane), which is halogen-free and offers exceptional resistance to mechanical stress, industrial oils, and coolants. This makes the EVC811 the ideal choice for use in machine tools and assembly lines where exposure to aggressive fluids is common. The gold-plated contacts ensure low contact resistance and long-term signal integrity.
Key Characteristics

Industrial Reliability
The EVC811 is engineered for «vibration-proof» operation. The coupling nuts feature an integrated locking mechanism that prevents the connection from loosening under heavy mechanical vibration. Its wide operating temperature range and high ingress protection ensure that it can be used in harsh washdown environments without the risk of electrical failure or signal degradation.
| Category | Specification |
| Current Rating | 4 A per contact |
| Bending Cycles | > 5 million (Drag chain capable) |
| Chemical Resistance | Resistant to oils and coolants |
Technical Note
When using the EVC811, ensure that the total current draw of the two connected devices does not exceed the 4A rating of the primary M12 male connector. This is essential to prevent overheating and potential damage to the I/O module port.
