Miniature Displacement Sensors


The A124 miniature measuring cell is a universal measuring instrument, suitable for all applications with limited space. Thanks to its small size it is ideal for highly customisable multi-dimensional measuring applications.

Its compact size, ease of use and universal applicability make the A124 the perfect solution for gauging designers.

Miniature Displacement Sensors

The 7x7x31 mm compact dimensions allows the cell to be used instead of probes or transmission devices for limited space applications.

Despite its small size the A124 cell features an interchangeable contact, a feature that is usually only found on larger measuring devices. This is a time and cost saving solution as the contact can be replaced without having to disassemble the whole measuring cell. Different types of contacts can be used based on the application without having to use special cells.    

The universal applicability is determined by the possibility of using the A124 to resolve the most disparate measuring problems guaranteeing great reliability and accuracy.
