Normally Open Current Sensor Switch Adjustable SZC23-NO-AL-CH AC 0.2-30AWThe SZC23 series AC Sensor Switch is designed and manufactured to solve the problem of AC monitoring. It uses the principle of mutual inductance to sense the alternating current, isolate the alternating current, and output the normally open or normally closed switching signal to directly control various industrial automation equipment, such as flash, buzzer, relay, single-chip or other power load equipment. Compared with traditional mutual inductors, thermal protectors and other devices, the use of this device can not only get more accurate and timely control, but also can greatly simplify the design and reduce costs. Features: 1. Self-powered, no external power supply required.2. 0.2-30A AC operation current, adjustable by potentiometer.3. The LED indicator can conveniently and intuitively indicate the working status of the switch.4. High power MOS tube non-contact electronic switch.5. The switch has no limit on the number of times you open and close, and the response speed reaches ms.6. Simple structure design, insulation withstands voltage up to 2000V.7. The hysteresis is less than 1% and can be used in strong magnetic conditions.8. The outer casing is made of ABS self-extinguishing material.9. It is suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch with automatic control system and so on.
