The 3-wire-PNP cylinder sensor is mainly used to detect the position of the piston in the cylinder, and the user can directly install it in the cylinder to use. As a detection device, the sensor is the primary link to realize automatic control and detection, and it can meet the various requirements of users for equipment information transmission, processing, storage, recording, display and control.

Tips: Possible causes of magnetic switch failure
The 3-wire-PNP magnetic sensor is fixed in the groove on the outer wall of the cylinder. There is a magnetic ring on the cylinder piston that moves with the piston. When the piston moves near the magnetic switch, the magnetism of the magnet will cause the magnetic switch to send out a signal. The light is only for easy identification.
When the cylinder is working normally, the position of the magnetic switch is fixed at the ends of the two ends of the cylinder, the indicator light will be on at the two points of the piston rod at 0 stroke and full stroke. If the light on the magnetic switch is off, it means the installation position is wrong. After adjusting to the accurate position, it needs to be fixed and the position cannot be changed casually.
If the magnetic switch cannot accurately send out signals, it may be:
1. The magnetic switch does not match the cylinder.
2. The internal coil of the magnetic switch is damaged.
The 3-wire-PNP cylinder electric type magnetic sensor is used to detect the position of the cylinder stroke. There is no need to install a machine-controlled valve (or stroke switch) and its mounting frame at both ends of the stroke, and there is no need to set a bumper at the end of the piston rod, so it is convenient to use. Its structure is compact, very reliable, and has a long service life. The magnetic sensor's maximum contact capacity is 6 W. There is no doubt that the cylinder switch can fully meet your needs.
