Robust Mechanical Construction
The Siemens 6ES5704-4BF00 features a zinc die-cast housing that provides excellent mechanical protection. This metal shell shields the connector from physical impacts and reduces electromagnetic interference. The gold-plated contacts ensure low and stable contact resistance over the product’s lifetime.
Reliable Electrical Performance
Gold-plated contacts maintain a contact resistance of less than 10 mΩ initially, ensuring stable signal transmission. The connector supports rated voltages up to 60V DC and currents up to 1A per pin. These ratings cover typical S5 system requirements for both digital and analog signals.
Simplified Assembly and Maintenance
The connector accepts wire cross-sections from 0.14 to 0.5 mm², accommodating various field cable types. Its screw-termination design enables straightforward assembly without specialized crimping tools. The compact D-Sub form factor also facilitates connection and disconnection during maintenance.
Compatibility and Versatility
This connector integrates seamlessly with S5-100U and S5-95U I/O modules and communication processors. It supports screened cables for enhanced signal integrity in noisy environments. The broad operating temperature range from -25°C to +70°C suits diverse industrial settings.
