Product details

What this Hall Effect sensor does on your board

The MAX9921AUB+ is a Hall Effect sensor from Analog Devices that accepts a voltage input and delivers a logic-level output — a clean on/off signal for position, proximity, or rotation sensing. It draws 1.3 mA from the supply, low enough to keep the sensor alive in battery-backed or always-on subsystems without eating into the power budget.

Package and mounting — fits a tight PCB footprint

Verify the land pattern against your assembly house's stencil aperture for the 0.118-inch body width; no surprises if you have placed other 10-MSOP Hall sensors before.

Marked as Active in the lifecycle record, so there is no last-time-buy clock running on this part. ROHS3 compliant, which clears the EU material restrictions for new designs.

Frequently asked questions

What is the output logic type of MAX9921AUB+?

The output is a logic-level signal, meaning it switches cleanly between a logic high and low — suitable for direct connection to a microcontroller GPIO or a digital input on a PLC module. No external comparator or level shifter is needed for typical 3.3 V or 5 V logic families.

Is MAX9921AUB+ RoHS compliant?

Yes, it is ROHS3 Compliant, meeting the latest EU restriction-of-hazardous-substances directive. No exemption declarations are needed for standard commercial or automotive BOMs.
