-40 degree temperature resistant proximity switch FQD-1415PKT/E product description: In general industrial places, eddy current proximity switches and capacitive proximity switches are usually used. Because these two types of proximity switches have higher environmental requirements. When the tested object is a conductive object or an object that can be fixed on a metal object, eddy current proximity switches are generally chosen because of their response frequency, good resistance to environmental interference, wide application range, and wide range. If the measured object is non-metallic (or metallic), liquid level, powdery substance, plastic, etc. A capacitive proximity switch should be selected. This type of switch has a response frequency but good stability. Environmental factors should be considered during installation. If the measured object is a magnetic material or if magnetic steel is buried inside the measured object to distinguish it from objects moving together, a Hall proximity switch should be used. In environments with good environmental conditions and no dust pollution, photoelectric proximity switches can be used. The photoelectric proximity switch has almost no impact on the measured object during operation. Therefore, it is widely used in both high demand transmission machines and Yancao machinery. In anti-theft systems, automatic doors typically use pyroelectric proximity switches, Chaoshengbo proximity switches, and microwave proximity switches. Sometimes, in order to improve recognition reliability, the above-mentioned proximity switches are often used in combination. Regardless of the type of proximity switch selected, attention should be paid to the requirements for various indicators such as working voltage, load current, response frequency, detection distance, etc. Temperature resistant proximity switch FQD-1415PKT/E proximity switch, QRX7500-KG,
