0.56 Blue LED Rarcing Car Tachometer Gauge Hall Proximity Switch Sensor NPN new

Description

Product Description
Overview:
The digital panel meter adopts the latest A/D conversion chip and high-stability reference IC, and adopts chip components, and the circuit design is reasonable. It can be applied to the measurement of voltage and current, or it can be connected with external sensors to measure various physical quantities such as temperature, pressure and displacement. It should be used for display of various digital instruments. The product has good stability, high measurement accuracy and strong anti-interference ability. The exterior is standard in size and easy to install.

8. Weight: about 50G
9. Over-range display: the first position shows "1" or "-1", the last three digits do not display
Precautions for use:
1. Connect the plug correctly according to the wiring requirements.
2. Should avoid strong electromagnetic interference, the measurement wire is best to use shielded wire or twisted pair.
3. The counter signal and the switch or circuit of the clear signal input should be as close as possible to the terminal of the counter to make the signal line as short as possible.
4. Avoid with other wires such as strong electric wires or power wires or stranded wires to avoid unnecessary interference. If necessary, use shielded wires and the shield is connected to the counting terminal “+”.
5. It is not recommended to use mechanical switches or micro switches, because their life is relatively short, it is easy to count down after a long time; if using mechanical switches or micro switches, please try to use better quality, so as not to count errors, strong Recommended magnetic switch.
Pacage Include:
1 × Blue LED tachometer
