Standex Detect - Reed Liquid Level Sensors
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.

Reliable Magnetic Switching for High Voltage Applications
The high voltage reed switch series delivers reliable magnetic switching for applications requiring elevated voltage and current handling. Capable of switching up to 10,000 VDC and with breakdown voltages reaching 15,000 VDC, these switches are engineered for high-performance environments such as photovoltaic systems, medical equipment, and automated test systems.
Available in glass body lengths starting at 14 mm, the series includes surface mount (SMD), through-hole, and free-standing options. These reed switches can carry continuous currents up to 15 Amps and pulsed currents up to 30 Amps, making them ideal for proximity, position, motion, and end-limit sensing.
For enhanced durability and simplified integration, these switches can be packaged as high voltage reed relays. Popular relay series such as H, HE, HM, KT, SHV, LI, and BE provide a range of contact configurations and insulation resistance exceeding 10¹³ Ohms, supporting both pick-and-place automation and high-voltage isolation.
Reed Relay Modules integrate multiple high-performance reed relays into compact, ready-to-use packages for efficient signal switching in space-constrained designs. Available in 8-channel configurations, these modules simplify circuit design by combining switching functionality with integrated driver electronics and advanced packaging.
The RM05-8A-SP Series features an 8-pole relay configuration housed in a dual-in-line through-hole package, equipped with MAX4823 integrated drivers and kickback protection—eliminating the need for external activation circuitry and reducing PCB footprint.
Reliable Break-Before-Make Switching with Form C Reed Technology
Changeover reed switches, also known as Form C or SPDT (Single Pole Double Throw) switches, feature three contact leads and operate with a break-before-make switching sequence. This means one contact disconnects before the other connects, ensuring clean signal transitions and reducing the risk of short circuits.
Changeover reed switches are ideal for applications requiring reliable switching between two circuits, such as signal routing, sensor feedback, and control logic.
These switches can be integrated into standard sensors and reed relay assemblies, and custom configurations are available to meet specific design requirements.
The high frequency reed switch series is engineered for precision switching in RF and high-speed digital applications. These switches are optimized to handle signals from DC up to 7 GHz, making them ideal for use in telecommunications, computing, and advanced test equipment.
With nickel/iron leads offering high magnetic permeability, these reed switches deliver exceptional linearity across a broad frequency spectrum. Their compact form factor allows for high-density PCB mounting, and internal shielding ensures minimal electromagnetic interference, even in tightly stacked configurations.
These switches are commonly integrated into high-frequency reed relays for enhanced durability and performance.
