If you suspect a product you have purchased from Dart Sensors is faulty, you must obtain an RMA (Returned Materials Authorisation) number before returning them. Failure to obtain an RMA number will result in all items being sent back to you without processing.
An RMA can be obtained by using the contact form on this website, quoting the following information:

• Our order reference
• Invoice number
• Batch number of the product
• Details of the fault

We will then contact you to advise of a course of action.

Remember that the more detail you put into the fault desctription, the easier it will be for our engineers to reproduce the alleged fault.

In order to expedite your returns please ensure you have marked your RMA number clearly on the outside of the package.
Ensure the goods are securely and carefully packed. Items that are not packed correctly will be rejected and your entitlement to a replacement or refund will be void.

Please contact our Customer Services Department if you require advice on how to properly pack your item.

Include any manuals, datasheets and accessories that came with the product.

Please note that returned items are tested for the faults that are indicated within your fault description and for basic operation of the product. If these faults are not found, then the product will be returned to you and a carriage/handling fee will be charged.

Returned items confirmed as faulty will be replaced by an identical product (or a product of similar specification), sent for repair or credited depending on the age, condition and status of the product and the availability of an appropriate replacement.
