1. The on-time of the capacitive proximity switch is 50ms. Therefore, in the design of the user's product, when the load and the proximity switch use different power sources, be sure to turn on the power of the proximity switch first.
2. Capacitive proximity switches can theoretically detect any object. When detecting a high dielectric constant object, the detection distance should be significantly reduced. Even if the sensitivity is increased, the effect will not be effective.
3. When using inductive loads (such as lamps, motors, etc.), the transient inrush current is large, which may deteriorate or damage the capacitive proximity switch of the AC two-wire. In this case, please use the AC relay as a load to convert. .
4. Do not use the proximity switch in a DC magnetic field environment above 200 Gauss to avoid malfunction. 5. The DC two-line proximity switch has a static leakage current of 0.5-1 mA. When some DC DC line proximity switch leakage current requirements are high, try to use the DC three-line proximity switch.
6. In order to make the capacitive proximity switch work stably for a long time, because it is affected by factors such as humidity and dust, it is necessary to carry out regular maintenance, including whether the installation position of the detecting object and the proximity switch is moving or loose, wiring and connection. Whether the parts are in poor contact and whether there is dust adhesion.
7. Avoid proximity switches in chemical solvents, especially in environments with strong acids and bases.
