Sensor Solutions offers Reed Switches with varying sensitivities and power switching capabilities with normally open or normally closed outputs as well as Bistable Reed Switches with a latching output.

Such an electrically latching reed relay requires continuous power to maintain state, unlike magnetically latching relays, such as ferreed (ferrite and reed relay) or the later remreed (remanent reed relay).

Jan 10, 2023 · When subjected to a brief pulse of relatively low input current, the coil (s) in a latching relay switch generates a magnetic field, pushing or pulling the armature - often known as a ‘reed …

This tutorial will define key terms Form B, latching sensors, and relays. The module will also describe the structure and function of latching and Form B reed relays and sensors.

To accommodate Form B or 2 Form A contacts the relay is slightly under 3/8” high. These relays offer mercury reed contacts 8, 12, or 14 pins and a variety of other options. All relays mate with the …

Feb 8, 2019 · A latching reed relay uses a Form A switch magnetically biased by permanent magnet as well as latching and unlatching coils. A magnetic pulse generated by one or the other coil latches and …

Jun 27, 2021 · A SIMPLE explanation of Latching Relays. Learn what a Latching Relay is, how a Latching Relay works, and a Latching Relay circuit diagram. Also known as impulses, bistable, keep, …

Oct 21, 2025 · View complete drawings, specifications, usage notes and applications for the R2E bistable / latching reed sensor.

Apr 29, 2025 · Most reed relays are not polarity-sensitive, meaning the coil can be energized with either polarity. However, some latching reed relays may require specific polarity for setting and resetting …

Latching reed switches use two permanent magnets to achieve the latching function. The first magnet is partially magnetized. Bringing the contacts closer together, but they still remain open. The second …

Get a clear relay definition and understand how they work. This guide explains the 5 most common types: electromagnetic, solid-state, reed, latching, and time delay.

Reed relays are available in several forms, including Form A (Normally Open), Form B (Normally Closed), and Form C (Changeover), as well as latching relay options.

Feb 1, 2023 · By the end of the guide, you should be familiar with the different applications for reed switches, know what a reed relay is, and understand what it means for reed switches to be normally …

Aug 12, 2024 · Latching reed relays, also known as bistable reed relays, maintain their state (open or closed) even after the coil current is removed. These relays use a permanent magnet to hold the …

Choose the right reed relay for your application with Cynergy3’s expert guide. Understand key factors like voltage, switching current, and coil configuration to ensure optimal performance.

Jun 10, 2023 · Reed relays require low coil current and are capable of fast operate and release times. Dual coils in some reed relays allow for latching capability. Contact forms include DPDT, DPST, …
