A3290KLHLXT — Latching Hall Effect Switch (SOT23W3), Quantity: 1 Key benefits Reliable magnetic sensing: Latching Hall effect switch detects magnetic field changes and holds its output state until the opposite polarity is applied, reducing the need for continuous monitoring. Space-saving package: SOT23W3 footprint fits compact PCBs and tight enclosures, enabling smaller product designs and easier integration into space-constrained assemblies. Simple digital output: Provides a stable latched signal suitable for reading by digital logic or microcontroller inputs, simplifying downstream circuitry. Single-unit packaging: Supplied as one device, ideal for prototypes, repairs, or low-volume builds without excess inventory. What makes it useful Function: Latching Hall switch that senses magnetic polarity and maintains its output state until reset by the opposite magnetic field. Suited to applications that require a maintained on/off indication based on magnet position. Compatibility: Designed for use in Hall Effect Switches / Latches IC applications — integrates easily with standard PCB layouts, digital control systems, and common low-voltage electronics. Size and material: Available in the compact SOT23W3 package for reliable surface-mount assembly and low-profile installations. Performance: Built for dependable magnetic sensing and stable latched output behavior, helping reduce false triggers and simplifying system logic. Practical applications Door, lid, or safety interlocks: Detect open/closed position and hold the state until intentionally reset, useful in access control and safety mechanisms. Proximity and position sensing: Replace mechanical reed switches in compact consumer or industrial devices where a maintained state is required. Rotary and linear position detection: Useful for simple encoder or position-sensing tasks where a latched response to a magnetic pole is needed.
