Review the details below to determine how these discontinuances will affect your products and/or operations.

Which products will be discontinued?

The ioThinx 4533-LX (V1) Series was created April 1, 2024, to prevent software and hardware incompatibility issues when upgrading the ioThinx 4533-LX Series from v1.x to v2.0, as some users may not be able to immediately redevelop or migrate to the new platform.

This model retains the same hardware and software as the ioThinx 4533-LX Series v1.x and will be supported until April 1, 2026, giving users two years to complete the product transition.
