Application industries
From UDK20 to UDK21.
UDK20. A trusted presence on the production floor. 2026 marks the transition to its next-generation successor, the new UDK21. The same proven functions and measurement performance, with more intuitive operation and additional features that make everyday use easier.
Continuity for your system
Functional compatibility with the previous-generation UDK20 supports existing interfaces, recipes and software integration. The upgrade configuration is reviewed against your current model and installation.
Updated sensors and connections
New UDK21 systems use the PW42BGS sensor and an 8+1-type SBCPWBS-GG cable. Reusing UDK20 sensors and cables with 6+3-type connectors requires a separate adapter cable.
Keep your sensor bracket
The SHX42 sensor bracket is compatible with both UDK20 and UDK21.
Introductory pricing
For a limited time, UDK21 systems are offered at the same unit price as UDK20. Contact HAN SAE for the offer period and terms for your configuration.
