Specification

The SIEMENS SIMATIC S5 6ES5497-4UB31 front connector is a critical component for industrial automation systems, specifically designed for the S5 family of programmable logic controllers (PLCs). This connector ensures a robust, low-resistance electrical interface between field devices and the S5 I/O modules, such as those in the 6ES5 48x series. Engineered for long-term reliability in demanding factory floor environments, the 6ES5497-4UB31 features a durable thermoplastic housing with high dielectric strength, accommodating up to 48 screw terminals for flexible wiring configurations. It includes integrated coding keys to prevent mismating and a strain relief mechanism to protect cable connections from vibration and mechanical stress. With a voltage rating of 250V AC/DC and a current rating of 10A per contact, this connector is suitable for both digital and analog signal transmission in control systems. Below are the detailed technical specifications:
