Siemens 6FX2003-0SU17 Signal Connector

Overview

The 6FX2003-0SU17 is a 17-pole signal connector for Siemens motion and control cabling. Siemens data identifies it as a union nut socket package supplied with 1 × 17-pole insulator, 17 contacts for 0.08–0.22 mm², 17 contacts for 0.20–0.56 mm², and 2 cable terminals for 6.5 to 10 mm and 10.1 to 13 mm cable diameters. It is a connector assembly for signal wiring and cable termination, not an active electronic module.

This part is well suited to original cable assembly, replacement harness work, and field repair where the connector format, conductor size, and cable clamping range must match the existing Siemens cable structure.

The complete packaged set makes it easier to restore the original connection layout without mixing incompatible contact or terminal parts.

Technical Data

Application Value

This connector fits servo signal cables, machine-side signal harnesses, control interconnection cables, and replacement cable builds where a multi-pole industrial connector must match the original assembly.

Because the package includes the insulator, contact sets, and cable terminal parts, it is especially useful where cable rebuilding has to be completed cleanly and without changing the original connector family.

Selection Notes

For selection, the most important points are the 17-pole layout, the supported wire cross-sections, and the cable outside-diameter range. If the conductor size or cable diameter does not match the connector kit, the finished cable may not terminate correctly or clamp securely.

FAQ

Q1: What exactly is 6FX2003-0SU17?
It is a Siemens 17-pole signal connector assembly. The published package includes the socket body, the 17-pole insulator, two full contact sets for different conductor-size ranges, and cable-terminal parts for two cable-diameter ranges.

This means it is intended for complete cable-end assembly or connector replacement, not as a loose shell only.

Q2: Is this a connector only, or does it contain electrical components?
It is a connector-only product. The published contents are mechanical and termination parts: socket, insulator, contacts, and cable terminals. It does not function as a controller, feedback module, or interface board by itself.

Q3: Why are there two different contact-size ranges?
Because the connector supports more than one conductor cross-section. One set is for 0.08–0.22 mm², and the other is for 0.20–0.56 mm².

This is important when rebuilding a cable, because the contact must match the wire size for secure crimping and stable long-term signal transmission.

Q4: Why do the cable terminal ranges matter?
The cable terminal range determines whether the connector can grip and seal the cable correctly.

This model includes terminal parts for 6.5 to 10 mm and 10.1 to 13 mm cable diameters. Matching the cable size helps maintain strain relief and prevents movement from transferring directly into the contact area.

Q5: What should be checked before ordering?
Check the installed connector code, confirm the system needs a 17-pole signal connector, verify the wire cross-section, and confirm that the cable outside diameter falls within one of the listed terminal ranges.

Those points decide whether the connector will fit the existing assembly correctly.
