Description
Features:
| CATEGORY | SPECIFICATIONS |
|---|---|
| Product Type | Hall Effect Latching Sensor |
| Model | A3144E / US1881 |
| Working Principle | Detects magnetic field; output toggles based on magnetic polarity |
| Output Type | Digital (Open-Collector) |
| Output Behavior | LOW when magnetic field > Bop; HIGH when field < Brp (with polarity reversal) |
| Operating Voltage | 3.5V – 24V DC |
| Output Current | Max 50 mA (sinking) |
| Current Consumption | Low power consumption |
| Internal Components | Hall generator, amplifier, Schmitt trigger, bandgap regulator |
| Noise Handling | Built-in hysteresis for noise rejection |
| Temperature Feature | Temperature compensated |
| Protection Feature | Reverse polarity protection |
| Package Type | TO-92 |
| Sensitivity Type | Latching (state changes with magnetic polarity reversal) |
| Switching Mechanism | Triggered by magnetic flux density thresholds (Bop and Brp) |
| Advantages | Small size, durable (no glass), reliable compared to reed switches |
| Applications | Position sensing, speed detection, proximity sensing, motor control |
