These adapter plates support the ZEISS VAST XXT sensor. This scanning sensor allows high-precision scanning at the ZEISS RDS swivel/rotate joint. The refined bearing point of the XXT adapter plates ensures system stability and a high degree of accuracy at the same time. The gold-plated contact points improve electrical conductivity, which ensures more robust data transmission. When assembling the stylus systems, the limit values for XXT measuring heads regarding length and weight must be strictly observed. For TL1 and TL2 or TL4, the maximum weight including adapter plate is 10 g, for TL3 15 g. Optionally, the adapter plates are already equipped with an extension with cone holder. Thus, connecting elements with cone adapter can be used.
