Feature: 1. The LED status indicator can conveniently and intuitively indicate the working status of the switch; high‑power for MOS tube non‑contact electronic switch; the switch has no limit on the number of on‑off times, and the response speed reaches the ms level. 2. Through core structure design, isolation withstand voltage up to 2000V; hysteresis less than 1%, can be used under strong magnetic field conditions; switch maximum AC and DC load up to 0.3A 135V AC/DC. 3. This switch is self-powered, no external power supply is required, and the action current 0.5/1.5A-200AAC can be adjusted by a potentiometer. 4. The shell of this switch is made of self‑extinguishing material ABS, which is durable. It is an ideal choice for automatic industrial control equipment and power monitoring. 5. The switch has the advantages of high accuracy, stable performance and long service life.

Product Introduction: SZC03 series AC current induction switch is designed and produced to solve AC current monitoring. It uses the principle of mutual inductance to isolate AC current by inducing AC through-core current, output a normally open or normally closed switching signal, and directly control various automated industrial control equipment compared with traditional transformer, thermal protectors and other devices, using this device can not only obtain more accurate and timely control effects, but also greatly simplify design, reduce costs, and greatly improve the overall competitiveness of the product..Size: Approx. 80mm / 3.1in20mm / 0.8in 63mm / 2.5in 3mm / 0.1in 90mm / 3.5in 100mm / 3.9in 31.8mm / 1.3in Diameter: Approx. 3.85mm / 0.2in Package List: 1 x Current Mutual Inductance Switch
