Used Connection Adapters – Buying and Selling

Used connection adapters are considered for programming connections to PLCs and controllers, adapting connectors or matching device interfaces. Passive connection adapters, electrical interface converters and protocol gateways perform different functions. Select a product for the connection or conversion actually required.

Before buying, verify the complete model code, target device series, port type and connector pinout. Compare signal levels, supported protocols and communication speeds, any galvanic isolation and power requirements. Check whether an external power supply is needed. For programming adapters, confirm operating-system, driver and engineering-software compatibility.

Condition and testing: Disclose damage to ports, pins, terminals, cables or housing. The test statement should identify the devices, ports and settings used for data-transfer checks. Clarify configuration access for active devices and whether cables, terminal blocks, power adapters and any software/licences are included in the sale. State known faults and repair history separately.

Sale terms: The seller named on the product page is the contact for specifications, condition/test statements and any warranty. Boxed or unused condition does not imply a warranty. There is no category-wide testing or warranty commitment; technical support and application consultancy are not provided through this section.

Stock and ordering: Listings are updated at average intervals of 10 days, so a sold item may remain visible briefly. Confirm availability, price and delivery with the relevant seller before ordering. Browse other equipment through the used equipment categories, or search by brand on the second-hand homepage.

Selling connection adapters: Email the manufacturer, complete model code, quantity, operating or faulty condition, asking price and clear product/nameplate photos to otomasyonavm@gmail.com. Include port photos, available test information and details of missing accessories. We do not purchase products without an invoice. Submitting details does not constitute a commitment to purchase.
