Sensor wiring instructions:

Main application areas: KPM18 miniature spliced linear displacement sensor, fisheye universal joint splicing at both ends, suitable for installation in small size and swinging, no special requirements for installation neutrality. Such as: injection molding machine thimble, shoe machine, 3D seat (5D seat), prestressed jack, robotic arm, robot, extractor, brick machine, ceramic machinery, sluice control.

Sensor installation instructions:

1. Select the linear displacement sensor range to leave a margin. Generally, select the range of the larger specification based on the actual stroke. When installing the sensor, leave the remaining amount at both ends evenly. After adjusting the position, lock the bracket screws.

2, the sensor installation should pay attention to the installation of the universal joint, adjust the neutrality. If the centering deviation and the tilt deviation are large at the same time, it will affect the measurement stability and service life of the sensor.

3. The linear displacement sensor is used as a voltage divider to access the circuit, and the actual value of the measured position is displayed as a relative voltage.

4. The sensor supply voltage should be stable, and the industrial power supply requires ±0.1% stability, otherwise it will cause large fluctuations in measurement data.

5, the power supply must have sufficient capacity, if the power supply capacity is too small, it is easy to cause the display data to jump, especially when the solenoid valve drive power and sensor power supply together, it is more prone to digital jitter.

6, there can be no external interference, including static interference and high frequency interference. Therefore, the sensor signal line should be routed to the power line of the device; the sensor should be installed with a forced grounding bracket and the sensor housing should be well grounded; the signal line should be shielded, and the shield should be grounded or connected to the DC power supply at one end of the box. negative electrode.

7. The sensor should be wired correctly. If the wiring is wrong, the sensor may be seriously damaged.

8. Long-term use of sensors, due to the intrusion of water, oil, dust, etc., affecting the contact resistance of the brush, which will cause the sensor measurement data to jump.
