Use this magnet from Sensata Cynergy3 to operate your reed switch. It works by pulling metal reeds inside the switch together or apart to complete or break a circuit, turning a device on or off. Thanks to its total flux of 9μWb, this unit will provide reliable switching at short distances. You'll find this component used in commercial applications such as machinery shut-off functions, speedometers and ABS in automotive systems.

• Compatible with standard and miniature-sized switches for versatile use
• Polarised along its length to allow for both direct and indirect actuation
• Activates standard-sized switches from 20mm away for up-close installations
• Orientations include parallel and perpendicular movement for versatility

Reed switches are highly compact and consume less power than most other switch types, making them an efficient choice.

Your choice of magnet should be determined by the sensitivity of your reed switch. The more sensitive the switch, the lower the total flux needed.
