Siemens 3SE6604-2BA01 Switch

Siemens 3SE6604-2BA01 is a magnetically operated switch contact block from the Sirius 3SE6 family, a rectangular block measuring 25 x 88 mm that carries two normally closed (2 NC) contacts and terminates via a four‑pole M8 connector. It is intended to be actuated by Siemens solenoids such as the 3SE6704-2BA or the extended‑travel 3SE6701-2BA, enabling robust interlock signaling in safety circuits. Wiring options include a 3 m LIYY cable (4 x 0.25 mm²) and an accessory 5 m coupling with connecting cable 3SX5601-3GA05, giving flexible installation in control panels. This magnetically operated switch block is designed for use in safety interlocks and guard‑door monitoring within industrial automation, providing reliable feedback to safety controllers in Sirius 3SE6 configurations. Compatible industry catalog references and replacement availability through Siemens Industry Mall and authorized distributors help ensure straightforward integration into existing safety assemblies.
