High precision, quick response, stable and reliable. 5. 8-24V wide supply voltage, suitable for various applications of RPM speed measurement. Spec: Item Type: Tachometer Operating Voltage: DC 8-24V, 40mA Display: 0.56inch green LED, 4 digit reading Measuring Range: 10-9999rpm Measuring Accuracy: ±0.1%, reading±1digit Display Refresh Rate: >3 times/sec Overrange Display: Display 1 or -1 in the first digit position, none in the last three digit positions Hall Proximity Switch Type: NPN NO Tachometer Size: 79x26x43mm / 3.11x1.02x1.69in PackageList: 1 x LED Tachometer 1 x Hall Proximity Switch 1 x Round Magnet 1 x Cable Notice: 1. Connect the plug correctly according to the wiring diagram. 2. The Hall switch is an NPN normally open type, and the detection distance of the Hall switch needs to be within 10 mm. The Hall switch is installed with a diameter of 12 mm and a wire length of 1m or less. 3. Avoid strong electromagnetic interference, the measurement wire is best to use shielded wire or twisted pair wire. 4. The counter and the clear input switch or circuit should be as close as possible to the terminals of the counter to make the line as short as possible. 5. Avoid the same tube or stranded wiring with strong electric wires or power wires to avoid unnecessary interference. If necessary, please use shielded wires, and the shielding layer is connected to the counting terminal +. 6. It is not recommended to use mechanical switches or micro switches, because their life is relatively short, it is easy to miscount after a long time; if using mechanical switches or micro switches, please try to use better quality one, so as not to m 7.Please note
