Description

TECHNICAL FIELD

[0001] The utility model relates to the field of magnetic sensor, in particular to a self-locking type micro sensor suitable for L-shaped groove cylinder. BACKGROUND

[0002] Magnetic material can change its magnetic properties after being exposed to heat, light, pressure, radiation and other external factors. Using such materials, various sensors with good reliability and high sensitivity can be made. These sensors use magnetic materials as their sensitive elements, hence the name magnetic sensor. With the increasing degree of industrial electrical automation, magnetic sensors are increasingly used in the precise control of cylinder travel and action.

[0003] Patent No. CN220873480U discloses a novel structure of a transverse locking magnetic switch. In use, the magnetic switch is placed from the side of the cylinder groove and placed in the active position. Press the magnetic switch and turn the screw at the front end of the magnetic switch clockwise. After turning the screw, the guide lock block moves forward with the hardware nut. The locking surface of the guide lock block moves downward under the action of the inclined surface of the hardware nut and extends out of the gap in the shell. After the guide lock block contacts the bottom surface of the cylinder groove, it will drive the magnetic switch to move upward. Since the opening of the upper door of the cylinder groove is small, the magnetic switch is stuck in the cylinder groove, thereby locking the magnetic switch. In the above structure, the magnetic switch needs to be placed from the side of the cylinder groove during installation. In the limited installation space, it is very inconvenient to install, especially when there is an obstacle at the side end of the cylinder, which may cause disassembly and use inconvenience.
