① Due to the ability to conduct testing in a non-contact manner, there will be no wear or damage to the tested object.

② Due to the use of contactless output, the lifespan is extended (except for magnetic type) by using semiconductor output, which has no impact on the lifespan of the docking point.

③ Unlike light detection, it is suitable for use in environments such as water and oil, and is almost unaffected by the stains, oil, and water of the test object. In addition, it also includes products with good Teflon shell type and drug resistance

④ Compared to contact switches, it can achieve high-speed response

⑤ Can correspond to a wide temperature range

⑥ Not affected by the color of the detected object, it detects changes in the physical properties of the detected object, so it is almost unaffected by surface color, etc

⑦ Unlike the contact type, it is affected by the surrounding temperature, surrounding objects, and similar sensors, including induction type and electrostatic capacity type. Sensors interact with each other. Therefore, for the setting of sensors, mutual interference needs to be considered. In addition, in the induction type, the influence of surrounding metals needs to be considered, while in the electrostatic capacity type, the influence of surrounding objects needs to be considered.
