Abstract
An encoder (10) for determining an angular position, the encoder (10) comprising a shaft (14, 16), a housing (18) and a transition region (32), the shaft (14, 16) projecting outwards from the housing (18) into the transition region (32), a measuring element (20) connected to the shaft (14), a sensor (22) for detecting the measuring element (20), and a control and evaluation unit (28) for generating, from the signals of the sensor (22), an angle signal in dependence on the angular position of the measuring element (20), wherein a protective cap (34) is arranged in the transition region (32) for protection against fluids (12) directed with pressure onto the transition region (32).
Claims18
An encoder (10) for determining an angular position, the encoder (10) comprising:
- a shaft (14);
- a housing (18) and a transition region (32), an upper part (16) of the shaft (14) projecting outwards from the housing (18) into the transition region (32);
- a measuring element (20) connected to the shaft (14);
- a sensor (22) for detecting the measuring element (20);
- and
- a control and evaluation unit (28) for generating, from signals from the sensor (22), an angle signal in dependence on an angular position of the measuring element (20),
- wherein a protective cap (34) is arranged in the transition region (32) for protection against fluids (12) directed with pressure onto the transition region (32), and
- wherein the protective cap (34) completely covers the upper part (16) of the shaft (14), the protective cap (34) extending an axial length of the upper part (16) of the shaft (14).
An encoder (10) for determining an angular position, the encoder (10) comprising:
- a shaft (14);
- a housing (18) and a transition region (32), the shaft (14) projecting outwards from the housing (18) into the transition region (32);
- a measuring element (20) connected to the shaft (14);
- a sensor (22) for detecting the measuring element (20);
- and
- a control and evaluation unit (28) for generating, from signals from the sensor (22), an angle signal in dependence on an angular position of the measuring element (20),
- wherein a protective cap (34) is arranged in the transition region (32) for protection against fluids (12) directed with pressure onto the transition region (32), and
- wherein the protective cap (34) is arranged in press fit on the shaft (14) such that the protective cap (34) rotates with the shaft (14).
