4 Digital LED Tachometer RPM Speed Meter Hall Proximity Switch Sensor NPN Set
4 Digital LED Tachometer RPM Speed Meter Hall Proximity Switch Sensor NPN Set
SKU:90UN077
Features:
Four-digit Reading
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.
Specifications:
Brand: MAXCOOL
Measurement accuracy: ± 0.1%, reading 1 word
Display mode: 0.56 blue LED
Display refresh rate: > 3 times / sec
Working power: AC / DC8-24V, 40MA
The external dimensions: 79 × 42 × 32MM
Installation size: 76 × 39MM
Weight: about 50G
Over-range display: the first position shows "1" or "-1", the last three digits do not display
Input pulse signal: NPN/PNP open collector, contact switch, non-contact switch, level pulse
Input signal voltage: Low level: -30V-0.6V, High level: 4-30V
Measurement range: Speed: 10-9999RPM
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.
Package Include:
1 × Blue LED tachometer
1 × Hall Proximity Switch Sensor NPN
1 x Bracket
Note:
Please allow slight 1-2cm difference due to manual measurement and a little color variation for different display setting.
