Frequently Asked Questions
What magnetic thresholds does the US5781EUA-AAA-000-BU switch at, and how does the hysteresis prevent false triggering?
The US5781EUA-AAA-000-BU operates with a BOP (operate point) of 7.5 mT and BRP (release point) of 12 mT, resulting in 5 mT of hysteresis. This 5 mT gap prevents the output from chattering when the applied magnetic field fluctuates near the switching threshold, ensuring clean digital transitions in vibrating or electrically noisy environments such as motor control panels.
Over what supply voltage range can the US5781EUA-AAA-000-BU operate, and which system voltages does it support?
The US5781EUA-AAA-000-BU operates from 3.5 V to 24 V supply voltage, making it compatible with 5 V microcontroller systems, 12 V automotive auxiliary rails, and 24 V industrial PLC inputs without requiring a separate voltage regulator. The 0 ppm/°C temperature coefficient ensures that switching thresholds remain stable across the full operating temperature range, eliminating threshold drift compensation in firmware.
For a contactless door-latch sensor needing to survive -40°C to +125°C, why is the US5781EUA-AAA-000-BU a strong candidate?
The US5781EUA-AAA-000-BU is designed for extended temperature operation with a 0 ppm/°C BOP/BRP temperature coefficient, meaning the 7.5 mT and 12 mT switch points hold constant from -40°C to at least +125°C. Combined with a 5 mT hysteresis and a plastic through-hole housing measuring 4.1 mm x 1.5 mm x 4.65 mm, it reliably detects magnet proximity for door-latch or panel-open sensing in outdoor industrial enclosures.
