Siemens Industrial Parts — New, Discontinued & Obsolete
Apex sources Siemens automation and control components for maintenance teams, system integrators, and procurement departments across Singapore, Southeast Asia and Australia — including discontinued and obsolete parts that Siemens no longer manufactures, new and reconditioned. If your SIMATIC system is approaching end-of-life, we can help with replacement planning to avoid unplanned downtime, sourcing a direct replacement or a compatible spare. Our component lifecycle management approach means panels running Siemens gear stay documented well before a part is discontinued. Sourcing drives or inverters for the same panel? Our Drives & Inverters page covers Siemens SINAMICS, Schneider Altivar and Omron drives across new, reconditioned and obsolete stock. Need contactors or circuit breakers? See our Breakers & Contactors page for new, reconditioned and obsolete SIRIUS contactors and Siemens circuit breakers. Looking for Siemens sensors or relays? See our Sensors & Relays page for new, reconditioned and obsolete proximity sensors, photoelectric sensors and control relays. Also see our PLC Systems page for new, reconditioned and obsolete Siemens SIMATIC controllers and the panels they run.
