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.

Engineered with specialized materials, extended creepage distances, and optimized internal geometry, these relays achieve insulation resistance levels up to 100 tera-ohms (TΩ) and in some cases, even 1,000 TΩ resulting in leakage currents in the picoampere range or lower.

These relays are available in configurations that support switching voltages up to 1,000 VDC and breakdown voltages up to 4,500 VDC, with custom options reaching 10,000 VDC switching and 15,000 VDC breakdown. Their high isolation and dielectric strength make them ideal for automated test equipment (ATE), semiconductor testing, and precision measurement systems where even the smallest leakage can impact results.

Compact, reliable, and built for demanding environments, High Insulation Resistance reed relays offer unmatched performance in high-voltage, low-leakage applications.

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.
