Standex Detect - Continuous Liquid Level Sensors
Continuous level sensors provide real-time monitoring across the entire height of a fluid container. These sensors use magnetic reed switches mounted along a PCB, combined with resistors to generate discreet voltage outputs. As a magnetic float moves along the sensor stem, it activates multiple reed switches, enabling precise and uninterrupted tracking of fluid levels. Advanced models like the CLS and HLS series incorporate capacitive or Hall effect technologies for high-resolution, programmable outputs in harsh environments.
More Product Information
Magnetic Float NBR or Nitrile Butadiene Rubber floats have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Magnetic Float PA or Polyamide floats are made of nylon, have a very high strength-to-weight ratio making them shock and abrasion resistant, enduring a pressure of 5 bar (73 PSI or 0.5 MPa). Magnetic Float PP (polypropylene) are rugged, highly resistant to many chemical solvents, bases and acids and have a water absorption of only 0.1%. V2A Floats are made of rust-proof stainless steel and are resistant to high temperatures making them ideal for the Food & Beverage industry among others.

Standard connectors are SMA (m) straight connectors, although other connectors can be used as required.
High Power Magnetic Switching for Demanding Applications
The high-power reed switch series offers robust magnetic switching solutions capable of handling up to 120 W and voltages as high as 1,000 VDC. Designed for demanding applications, these reed switches are available in various sizes starting from 14 mm, including surface mount and through-hole options for flexible integration.
These switches are ideal for proximity, position, motion, and end-limit sensing, and can also be packaged into high power reed relays for enhanced durability and simplified PCB mounting. Relay packaging supports both pick-and-place automation and high insulation resistance, with some models exceeding 10¹³ Ohms.
Popular series such as KT, SHV, LI, and BE offer a range of contact configurations, including SPST, SPDT, and multi-switch designs. Whether used in automotive systems or test and measurement equipment, these high-power reed switches deliver reliable performance where high voltage and current demands are critical.

Intrinsically safe reed relays and optocouplers are engineered for use in hazardous environments where ignition prevention is critical. Certified to ATEX standards and tested to ensure they do not become ignition sources, even in the presence of short circuits or adjacent component failures—these components are ideal for applications in explosive atmospheres such as mining, chemical processing, refineries, and power stations.
Designed to meet EN50020 safety standards, these relays and optocouplers feature tightly controlled air and creepage paths, high dielectric strength, and low-voltage coil inputs. With a maximum peak voltage of 375 V across input and output, and isolation distances up to 10 mm, they ensure safe operation under overload conditions. The Comparative Tracking Index (CTI) of the plastics used exceeds 175, and internal potting compounds provide additional insulation for long-term reliability.
Reliable Switching in a Small Footprint
The miniature reed switch series features compact, power-efficient magnetic switches with glass body lengths ranging from 9 to 14 mm. Designed for precision and versatility, these switches operate with no power consumption in their normally open state, making them ideal for energy-sensitive applications.
Available in a wide range of switching characteristics, including close differential, high current, mercury wetted, high-performance, and SPDT (changeover) configurations, this series supports diverse design requirements across industries. Their small footprint makes them especially valuable in miniaturized systems such as semiconductor testing equipment and medical devices, while also serving critical roles in telecommunications, security, automotive, appliances, and industrial automation.
