The 6ES5490-7LC11 is a high-quality front connector from the Siemens SIMATIC S5 family, specifically designed for secure and reliable connection of field devices to S5 programmable logic controllers. This 20-pin front connector is engineered for use with S5-115U, S5-135U, and S5-155U series I/O modules, providing a robust interface for digital and analog signals. Its screw-type terminal blocks ensure vibration-proof wiring, while the integrated strain relief and locking mechanism guarantee long-term stability in demanding industrial settings. The connector supports up to 1.5 mm² wire cross-sections, making it suitable for both signal and low-power supply connections. With a rated voltage of 60 V DC and current capacity of 10 A per contact, it meets the rigorous standards of factory automation and process control systems.
