IO-Link - M26 modules are industrial communication devices designed for automation systems, typically provided by various manufacturers rather than being a single brand. These modules are widely used in industries such as manufacturing, automotive, and machinery for enabling smart sensor and actuator connectivity. They support the IO-Link protocol, a global standard (IEC 61131-9) for point-to-point communication, facilitating easy integration with PLCs and industrial networks. Major companies producing IO-Link - M26 modules include ifm (Germany), Balluff (Germany), and Pepperl+Fuchs (Germany), offering rugged, high-performance solutions for industrial automation. Their products often feature M26 connectors, ensuring reliable data and power transmission in harsh environments.
