HTB100-P Precision Hall-Effect Current Sensor

HTB100-P Accurate, Reliable, Safe — Protecting Your Power Electronics System

Are you troubled by low accuracy in high-current measurements, electromagnetic interference that destabilizes signal integrity, or sensors that fail in harsh environments? These measurement challenges not only slow down your development but can also create system safety risks.

HTB100-P is the solution you need.

Why Choose HTB100-P?

Wide measuring range – handles surges with ease
Rated for 100A, with a maximum capacity of ±300A transient overcurrent. Even during equipment startup or sudden load changes that cause current surges, the HTB100-P operates reliably — no more measurement blind spots. With a wide bandwidth from DC to 50kHz, it captures DC, AC, pulsed, and mixed waveforms, meeting diverse measurement needs in one device.

1% high accuracy – critical data without compromise
±1% accuracy combined with ±1% linearity ensures every measurement is trustworthy. Whether for fine motor drive control or power supply condition monitoring, you get precise current data to support confident system decisions.

3µs ultra-fast response – catch instantaneous changes
Response time of just 3 microseconds – from the moment current changes to sensor output, it's nearly synchronous with the system event. For ultra-demanding applications like fast-protection power supplies and precision servo control, the HTB100-P delivers signals without delay, helping your system react instantly.

2500V isolation voltage – safe and worry-free
Using open-loop Hall-effect technology, it provides galvanic isolation between the primary (high-power circuit) and secondary (signal circuit). With 2500V isolation voltage, the power circuit is completely separated from the signal processing side – protecting downstream equipment and ensuring operator safety.

-40℃ to 80℃ wide operating temperature – built for harsh environments
From northern winters to southern summers, from factory floors to remote field equipment, the HTB100-P delivers stable output across -40℃ to 80℃ with minimal drift. It’s your reliable "current sentinel" in industrial environments.

PCB through-hole mounting – small size, space saving
Dimensions of only 39mm × 34mm × 11mm, single-aperture modular package, 4-pin soldered PCB mounting – footprint less than 4.3cm². For space-constrained board designs, the HTB100-P integrates easily without sacrificing performance.
