PROXIMITY SENSOR, CONTROL SYSTEM, AND EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2022/070712
Kind Code:
A1
Abstract:
The objective of the present disclosure is to improve detecting sensitivity with respect to a detection target. A proximity sensor (1) is provided with a conductor (3), a receiving electrode (4), and a first transmitting electrode (51). The conductor (3) has an upper surface (3U). The receiving electrode (4) is separated from the upper surface (3U) of the conductor (3) in an upward direction, and extends in a first direction. The first direction is perpendicular to the upward direction. The first transmitting electrode (51) is separated from the upper surface (3U) of the conductor (3) in the upward direction, and extends in the first direction. The first transmitting electrode (51) and the receiving electrode (4) are arranged side by side in a second direction. The second direction is perpendicular to both the upward direction and the first direction. In a cross section perpendicular to the first direction, an upper surface (5U) of the first transmitting electrode (51) is formed bulging upward.
