An industrial automation parts supplier built on verified originals, testing and long-term partnerships.
Muchen supplies original automation parts — PLCs, HMIs, servo drives, power supplies and protection devices — to panel builders, integrators and distributors. Our strength is range: 2,000+ part numbers across 22 brand lines, including obsolete and discontinued series that normal channels no longer carry. Send a model list; if the part still exists, we will find it — and if it is gone, we will tell you straight.
We keep a simple promise: original parts, verified quality and communication you can rely on. Every quotation is answered within 12 hours, and every shipment ships with full documentation.
Get a QuoteS7-300, S5, older Modicon and legacy HMI panels are the models we are asked for most — we search our supplier network model by model, not just the catalogue.
PLCs, HMIs, servo drives, power supplies, breakers and sensors — several brands on one purchase order, consolidated into one shipment.
We check series, revision and suffix against your list before quoting, so you never receive a near-match that will not fit the panel.
If a part is gone, we say so within 12 hours and propose an alternative — instead of taking the order and stalling.
