Series Features
MH21 Series Micro-Power Hall Sensor
Series DescriptionThe MH21 series Hall effect sensors are engineered for precision and durability in demanding environments. Housed in a robust, flange-mounted rectangular casing with cable terminals, these sensors offer solid-state reliability and consistent performance across a wide temperature range.
Design Notes:
Add an external pull-up resistor (RL) between VCC and VOUT for sinking output.
Use a bypass capacitor (CBYP) near the sensor to minimize external noise.
- Multiple Output Options: Available in switch, latch, and micro-power configurations to suit diverse application needs.
- Low Power Consumption: Micro-power versions operate on just 5μA average current at 2.5–3.5V, significantly lower than the industry standard.
- High Temperature Resistance: Standard operating range from -40°C to +85°C, with higher temperature variants available.
- Stable Activation Points: Ensures consistent sensing performance even in fluctuating environmental conditions.
- Compact & Customizable: Ideal for space-constrained applications with flexible design options.
