Company
A buying desk for electrical automation — not a generic parts website.
Riching Automation Limited is a Hong Kong B2B distributor of genuine PLC, HMI, VFD, servo, sensor, pneumatic and cabinet hardware. You send a nameplate or a BOM. We confirm the family, voltage class and lead time, with actual-shooting photos of the unit on hand.
- Nameplate firstBrand, full catalog number, voltage and firmware family before we quote a substitute.
- Stock you can seePhotos are shot on the unit in the warehouse — not a catalog render or a marketplace thumbnail.
- HK contractingExport documents from Hong Kong. Consolidation for South China when the shipment is more than a courier carton.
Who we are
Industrial distribution with a sourcing desk, not a shopping cart.
We buy and sell electrical automation and industrial control components for factories, OEM machine builders and maintenance teams. The catalog on this site is the stock we have photographed. Empty price means request a quote — lead time and Incoterms change with quantity and destination.
Most RFQs are discrete manufacturing and plant MRO, not green-field DCS. If the duty is a conveyor, a labeling cell, a pump skid or a drive-repair bench, we already know which families fail first and which ones we can still buy.
What we supply
The hardware a cabinet and a cell actually consume
Eleven shop categories, from the PLC and HMI down to the fuse, the M12 cordset and the IGBT brick. Click through to the SKUs we have on the shelf.
PLC & operator panels
CPU, I/O and HMI cut-outs that stay on the installed software family — DVP, SIMATIC, Micro800, FP7, KincoBuilder or EasyBuilder.
Drives & motion
VFD frames, ASDA / MINAS / Lexium servo and the encoder cables that belong to that axis. Voltage class and overload duty before the series name.
Sensing & interlocking
Photoelectric, inductive, pressure and safety-door devices quoted by the full type key — output, connector and sensing distance included.
Cabinet power & switching
TeSys / AF / DIL contactors, DIN-rail PSU, MCB / MCCB and the CLIPLINE layer a panel shop already draws.
Pneumatics on the cell
SMC and Festo cylinders, SY / ISO valves and ISE pressure switches the PLC already treats as a station.
Power modules for repair
Infineon, Semikron, Mitsubishi and Fuji bricks when the rest of the drive or welder frame is still worth keeping.
Who we quote for
Three desks we already know how to talk to
Machine builders
Repeat SKUs for a cabinet that already ships. We hold the family you standardized — not a one-off “similar” substitute — and pack with the datasheet your receiving team expects.
System integrators
A BOM with mixed Siemens, Schneider, Delta and SMC lines. We confirm each catalog string, flag a later revision that is only pin-compatible, and quote stock versus factory lead time on one sheet.
Plant MRO
Line-down spares identified from a worn nameplate. Send the photo. We match the last dash group before we talk about a cross-reference, and we ship the unit you can see in the gallery.
Working method
From nameplate to packed carton
-
1. Identify
Manufacturer, complete catalog / MLFB / type key, quantity, and a photo of the nameplate if the part is worn or painted over.
-
2. Qualify
Family, supply voltage, I/O type, encoder or brake options, and whether a later revision is drop-in — or only pin-compatible.
-
3. Quote
Stock or factory lead time, Incoterms, and the actual-shooting gallery so receiving can match the unit before it leaves.
-
4. Ship
Export documents from Hong Kong, datasheets in the carton, and a one-year parts warranty on items we sell as new genuine.
Hong Kong
Contracting and export documents
Sales desk Mon–Sat 09:00–21:00 HKT. Most complete RFQs get a stock or lead-time answer within one working day. Contracting, commercial invoice and packing list issue from Hong Kong.

Warehouse photos, then consolidation
Units on this site are photographed on the shelf before we list them. Multi-line orders can consolidate for a South China pickup or a single export carton instead of a stack of courier bags.
SEG Plaza, Huaqiang North Road
Futian District, Shenzhen
Ask for bonded spare kits when the line is allowed a planned stop, or a one-off when it is already down.
Manufacturers
Brands we already write quotes against
Each logo opens a short brief on electrical automation and industrial control, then the SKUs we have photographed.
Next step
Need a line-down spare or a cabinet BOM?
Put the brand, full catalog number, quantity and destination city in the RFQ. A nameplate photo saves a round of questions.
