This allows for design with larger air gaps between the sensor IC and the magnet or for the design engineers to decrease the total cost of their designs by using smaller, less expensive magnets.
In addition to high sensitivity, the four Standard Power series sensor ICs (SM351RT, SM451R, SM353RT & SM453R) feature a solid-state, non-contact, no-glass design that makes them durable and reliable. Their supply voltage range (3-24VDC), omnipolar operation, various package options and wide operating temperature range from -40 to +85°C (or -40 to +185°F) simplify the design-in processes for wired applications.
Potential applications include everything from flow sensing in HVAC and anti-tamper detection in utility meters, to RPM sensing in exercise equipment and door position detection.
Joshua Edberg, Director of Packaged Sensors, Sensing and Productivity Solutions, Honeywell, commented: “Market conditions and a greater demand for more-compact devices have many engineers looking for alternative components that simplify their designs without straining budgets. The Standard Power series sensor ICs provide strong alternatives to Hall-effect ICs at a time when rare earth magnet prices are high. They also are solid alternatives to reed switches when high reliability and durability are major considerations.”
