Ultra-Low-Power Omnipolar Hall-Effect Switch – Digital omnipolar Hall-effect switch optimized for lid/door detection, proximity sensing, magnetic position detection, industrial controls, consumer electronics, and battery-powered embedded systems. Operates from a 1.65 V to 5.5 V supply with an ultra-low 3 µA maximum supply current, making it ideal for low-power applications. Features a push-pull digital output, omnipolar operation (responds to either north or south magnetic poles), sleep mode, and high magnetic sensitivity with ±3 mT typical operate point and ±0.8 mT typical release point. Supports up to 5 mA output current, provides built-in hysteresis for noise immunity, and operates over a −40°C to +125°C temperature range. Housed in a compact 3-pin SOT-23 (DBZ) surface-mount package. #TexasInstruments #TMAG5231C1DQDBZR #TMAG5231 #HallEffectSensor #OmnipolarSwitch #MagneticSensor #PositionSensor #ProximitySensor #LowPower #BatteryPowered #SOT23 #EmbeddedSystems

Reflective Optical Sensor (Photointerrupter) – Reflective infrared optical sensor integrating an 850 nm IR emitter and silicon phototransistor receiver for object detection, proximity sensing, position detection, paper/media sensing, and industrial automation. Features a 2.3 mm sensing distance, daylight-blocking optical filter, and high ambient light immunity for reliable reflective detection. Operates with an IR LED forward current up to 50 mA, 1.25 V typical forward voltage, and a phototransistor collector-emitter voltage of up to 70 V. Provides fast response times, surface-mount (SMD) construction, and is specified for operation over a −40°C to +100°C temperature range. Housed in a 4-pin SMD reflective sensor package measuring approximately 4.2 × 2.5 × 1.7 mm.
