Current Sensing SwitchSwitch Type: Sensor SwitchItem Type: SwitchesSZC23 series AC current sensing switch is designed and manufactured to solve the AC current monitoring. It uses the principle of mutual inductance to sense the AC straight-through current, isolate the AC current, and output a normally open or normally closed switching signal to directly control various automation industrial equipment, such as flash, buzzer, relay, single-chip or other load equipment.Compared with traditional mutual inductors, thermal protectors and other devices, using this device can not only get more accurate and more timely control, but can also greatly simplify the design and reduce costs.Model Number: SZC23-NO-AL- Current Sensing Switch1. Self-powered, no external supply required.2. Action current 02-30A AC, adjustable with a potentiometer.3. LED indicator can conveniently and intuitively indicate the working status of the switch.4. High- MOS tube contactless electronic switch.5. The switch has on the number of opening and closing, and the reaction speed reaches the ms level.6. Straight-through structure design, isolation withstand voltage up to 2000V.7. Hysteresis is less than 1% and can be used under strong magnetic conditions.Suitable for AC current measurement and monitoring, AC motor overload protection, electronic switch of automatic control system and so on. supply: Not requiredRated load: less than or equal to 05A 240V AC/DCInput current: 02-30A ACSwitch on minimum: 05+/-02AMaximum overload: 100%Leakage current: less than or equal to 01AAccuracy: 1%Hysteresis: less than or equal to 1%Response time: less than or equal to 200msRepeatability: 100%Working temperature: -20~60 CelsiusWaterproof: IP30colour:blackMaterial:ABS+ electronic componentssize:Product size: 65*47*25mmHole diameter: 10mm / 04inPackage Contents:1 * Current Sensing SwitchOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
