2. Design and function
It is designed to be impact and vibration resistant and all electrical
components are protected against humidity (IP67 or IP69K). The
vibration resistance conforms to IEC 60751 (20 g, dependent on the
instrument version). The impact resistance of all versions meets the
EN
requirements of IEC 60751. Ensure that mechanical loads on the
connector are minimised, especially in case of increased ambient
temperatures or strong vibration loads.
The electrical connection is made via an M12 x 1 circular connector.
An adapter for electrical connection with angular connector per
DIN EN 175301-803 is optionally available.
