Reed liquid level sensors use magnetic floats and reed switch technology to detect fluid levels. As the float moves with the liquid, it activates reed switches housed within a stem, providing a reliable on/off signal or triggering multiple level points. These sensors are highly energy-efficient, drawing no power until activated, making them ideal for battery-powered or low-energy applications.

They are available in vertical or horizontal mount configurations and can be customized for various fluid types, temperatures, and pressures. With options for stainless steel or plastic housings, reed sensors offer a simple, cost-effective solution for fluid level monitoring in automotive, industrial, HVAC, and appliance systems.

The latching / bi-stable (1 Form E) reed switch is a magnetically operated switch designed for ultra-low power applications, particularly in battery-powered and energy-sensitive systems. Unlike traditional reed switches, this bistable variant maintains its contact state, either open or closed, without continuous power, thanks to its dual-magnet latching mechanism.

The switch operates by using two permanent magnets: one partially magnetized to bring the contacts near each other, and a second magnet that controls the contact state by reversing its magnetic field. This design allows the switch to remain in either the normally open (N.O.) or normally closed (N.C.) state until actively changed, making it ideal for applications requiring stable switching with minimal energy consumption.
