7.4 Housing mechanical specifications
The top casing of the MTi is made of anodized Aluminum 6082. The bottom plate is made of anodized
Aluminum 6082 The MTi connector socket and housing assembly features rubber O-ring sealing. The
MTi-100 series feature a vent that allows for the inside pressure to be the same as the ambient pressure
without compromising the ingress protection.
7.4.1 Environmental protection of the housing
All encased MTi’s are designed to withstand usage in application where dust and occasional water
splashing can be expected. However, Xsens in house testing has confirmed that the casing and
connector can withstand temporary environmental circumstances equivalent to Protection Classification
IP67 (sealed against dust, 30 minutes immersion at depth of 1 m).
