Search by exact part number.
Manufacturer order numbers help avoid quoting the wrong revision, processor, I/O or drive variant.
Availability transparency: A part number shown in this sourcing directory is a reference for enquiries, not a stock or price offer. AO checks each source, unit condition, quantity, delivery date and terms before making a quotation.

Common questions
Sourcing with clarity
Buying discontinued controls demands extra care.
Does an item listed here mean it is in stock?
No. These are reference examples and sourcing categories. For ready-to-buy AO stock, use our current stock listings.
Can you supply new or refurbished stock?
We can investigate different conditions; actual options depend on the individual source. We disclose the quoted unit's stated condition.
Will the replacement work in my machine?
Matching a part number is a first step, not a compatibility guarantee. Check revision, firmware, configuration, accessories and the original system.
Can you respond to an urgent breakdown?
Tell us if the machine is down and your required delivery date. We'll assess possible routes, without promising stock that isn't confirmed.
