What it is and what it connects
The Siemens 6ES7923-1BD00-0HD0 is a shielded connection cable for the SIMATIC ET 200SP HA distributed I/O system. It runs from a 37-pole D-sub connector on the I/O module side to bare ends with wire end sleeves on the field side, carrying 20 signal channels over a 3 m length with 0.56 mm² conductors.
Sourcing and lifecycle
RoHS compliance is confirmed effective from January 1, 2024, and REACH Article 33 information is available for the current candidate list.
Field termination note
The bare-end termination with wire end sleeves is designed for direct screw or spring-cage terminal blocks in the field junction box. The 0.56 mm² cross-section (roughly 20 AWG) suits standard I/O signal wiring. Shield connection is handled at the D-sub housing; maintain a continuous shield drain wire back to the panel ground for noise immunity on long runs.
