Application Situations

RedRock® Sensor Function	Typical Application	About the End Product	Customer Requirements	Recommended RedRock® Product
Signaling, Wake Up, Turn-On or Change Mode using an external magnet	Wearables, Implantablesm, Ingestibles, Hearing aids, IoT devices,	Small-size, ingress-protected, battery-powered. May stay in sleep mode for long periods of time.	Need: Foolproof means to conserve battery by powering device only when needed. RedRock@ Solution: Very low power magnetic sensor w/external magnet. Remove unit/device contain- ing sensor from package containing the magnet to power circuit via I-IC wake-up or a simple MOSFET to power entire circuit. • Contactless Activation - Small/Sealed unlike mechanical switch • Low-power unlike wireless	RR122-lA22-511/512, RR122-lB12-511/512
Rotation Counting	Metering (water, gas, electric) Any with a rotating element	Used with a rotating element - shaft, impeller, wheel where sensor needs to count rotation, speed and direction accurately.	Need: Count rotations/speed and/or direction of a rotating element. RedRock@ Solution: Sensor counts by detecting magnet on rotating element. • Use two sensors to also determine direction of rotation. • The sensor frequency must be at least 2x the product of the rotations per second and the number of magnet pole pairs	RR122-3C62-511, RR122-3C72-511, RR122-3CU2-515, Available in industrial temp (+850C) and wide tem ran e (+1250C)
Tamper Detection	Door security, Gas Meter, Water Meter, Electric Meter	Hermetically sealed, operates for years on a battery using a magnetic field to perform normal function but can be influenced by application of an external magnet.	Need: Detect illegitimate magnetic fields introduced as an attempt to tamper with an existing magnetic sensing function. RedRock@ Solution: Use a digital sensor matched to a field higher than legitimate field, or use an ana- log sensor to sense a wide field range.	RR122-1F22-511, RRII 2-1 G43-531/532†, †when not battery powered
Level / Linear Distance Sensing	Any with fluid tank/reservoir Linear motion elements	Any product with a tank or fluid reservoir. Any product with a mechanical element that moves on a rail.	Need: Determine position of element along a fixed path with high-accuracy. RedRock@ Solution: Place sensors with strategic spacing along the plane of mag net travel. • Sensors need sufficient sensitivity with excellent part-to-part accuracy. • Sensors can be digital or analog output. • Very low power and fast start-up time are often required to reduce battery consumption.	RR122-1B12-511/512, RR122-2B22-511, RR132-lB12-551/552, RR132-2E32-551, RR112-lG43-531/532, RR122-1F22-511, RR122-2E22-511, RR132-2E22-551, *Available in industrial temp (+850C) and wide temp range (+1250C)
Proximity Sensing	Numerous consumer, industrial, medical and commercial products	Any product with a moving mechanical element with magnet attached where proximity of the moving element needs to be sensing relative to a fixed element (e.g., lid or cover open/close detection)	Need: Determine if element is within range or in position. RedRock@ Solution: Use one or more digital sensors or use an analog sensor (field strength = distance). • Tight sensitivity limits (min/max) to improve consistency between units. • Low current consumption enabled battery operation. • Use multiple digital sensors oran analog sensor to detect multiple positions	RR122-1A22-511/512, RR122-1F22-511, RR112-lG43-531/532, RR122-1B12-511, *Available in industrial temp (+850C) and wide temp range (+1250C)
