The Real Risk Is Not Only Whether the Part Is Available
Finding a supplier that has the required model is only one part of the purchasing process. Before approving an order, buyers also need confidence that the offered product is the correct model, its condition has been explained clearly and the shipment will match what was approved.
Know Exactly Which Model You're Buying
Products that look almost identical may differ in voltage, firmware, communication protocol, hardware revision or model suffix. Every quotation is based on the complete model number rather than a general product family, helping reduce ordering mistakes before payment.
Review the Actual Product Before Payment
Where stock is available, buyers can request real photographs of the offered unit before confirming the order. Available evidence may include: Product appearance, Nameplate, Connector details, Packaging, Visible condition. This allows buyers to review the actual unit instead of relying only on catalogue images.
Product Condition Is Clearly Identified
Automation products are sourced from different supply channels and should not all be described as "new." Before quotation, the available condition will be identified clearly, including: Unused Old Stock, Surplus Inventory, Refurbished, Used & Tested. This helps buyers understand exactly what is being offered before making a purchasing decision.
Replacement Models Are Reviewed Carefully
A newer model is not always a direct replacement. Depending on the application, mounting dimensions, wiring, communication, motor compatibility or software may also need to be reviewed. Where replacement options are requested, Keentechi will help review compatibility before making recommendations.
Multiple Product Families Can Be Combined
Maintenance teams often need more than one automation component during the same repair. PLC modules, servo drives, HMIs and communication modules can be reviewed together and consolidated into one shipment whenever possible.
One Contact Throughout the Order
From the initial enquiry until shipment, buyers communicate with one contact who coordinates: Model verification, Quotation, Product confirmation, Inspection, Packing, Shipping documents, Tracking information. This reduces communication delays during international purchasing.

Understand the Product Before You Approve the Order
Industrial automation components are sourced from different channels, and not every available unit is in the same condition. Before placing an order, buyers should understand exactly what is being supplied and what level of inspection has been completed. Our goal is not to describe every product as "new," but to present its condition accurately so purchasing decisions can be made with confidence.
Unused Old Stock (NOS)
Products that have never been installed and remain unused in storage.
Depending on the manufacturing date and product type, buyers may wish to review packaging condition, storage history or battery status before purchase.
Surplus Inventory
Products released from distributors, OEM projects or industrial warehouses.
These products are often unused, although the original packaging may show signs of storage or transportation.
Refurbished Units
Previously used products that have been repaired, restored or serviced before being offered again.
Available inspection records and warranty terms should always be reviewed before approval.
Used & Tested
Products that have previously been installed and are supplied after agreed inspection procedures.
The inspection scope will be explained before shipment rather than assumed.
Available Inspection
Depending on the product type and available testing equipment, inspection may include:
- Exact model verification
- Complete suffix confirmation
- Nameplate inspection
- Housing condition check
- Connector inspection
- Terminal inspection
- Basic power-on verification
- HMI display and touchscreen check (where applicable)
- Packaging verification before shipment
Important Limitation
Inspection helps confirm the visible condition and agreed test scope of the offered product. However, a bench inspection cannot reproduce every operating condition inside the buyer's equipment. Any available testing will be described accurately instead of being presented as a guarantee of application performance.
