Strong Compatibility
TP-12 senses light in various colors and wavelengths, converts optical pulses into electrical pulses, and supports different power modes and connector options for project integration.
TP-12 Mini Optical Probe for Smart Meter Pulse Detection
The TP-12 optical scanning probe detects visible light and infrared LED pulses emitted by smart meters, then converts them into electrical pulses for calibration and pulse acquisition. It supports +5 V external power with LED indication and +3.3 V low-consumption battery-powered operation with the LED disabled.
ModelTP-12
Power SupplyDC 5 V / DC 3.3 V
Pulse FrequencyUp to 5 kHz
ProtectionIP54
Low-Power Optical Pulse Detection for Smart Metering
Flexible Fixed Method
The probe supports magnets, 3M double-sided tape and other mounting methods. Double-sided tape is widely used because it is simple to fix and protective for the meter surface.
High Sensitivity
With a maximum pulse frequency of 5 kHz and a minimum pulse width of 200 ms, TP-12 can detect different light colors with strong anti-interference performance indoors and outdoors.
Excellent Performance in Harsh Environments
PC enclosure material, optional strong magnetic fixing and long-lasting cable construction help TP-12 remain stable in demanding field conditions.
