Product family overview
Reed Sensor application and selection guide
Reed sensors and magnetic switches detect position, level or movement through a magnetically actuated contact; operate/release distance depends on magnet, orientation, sensitivity and installation geometry.
Use this family when a sealed non-contact or magnetically actuated sensing point is required. Final magnet distance, cable length and environmental rating should be confirmed for each installation.

Engineering selection notes
Before choosing a model
These notes keep product pages useful for engineers while avoiding overclaims. Final ratings remain model- and application-specific.
Series comparison
Reed sensor application comparison
Choose the sensor style from the target, medium and installation environment, then confirm cable, connector and actuation distance by RFQ.
| Sensor use case | Typical construction | Signal output | Selection focus |
|---|---|---|---|
| Position / proximity | Molded reed sensor with external magnet | NO / NC reed switch output | Actuation distance, magnet type and mounting gap |
| Level / float sensing | Float or level sensor body | Level state switching | Media compatibility, temperature and mounting thread |
| Door / interlock | Compact magnetic switch | Controller / PLC input | Cable length, housing strength and environment |
| Custom OEM sensing | Sensor capsule, lead wire or connector options | Model-specific output | Sealing, connector, cable and production volume |

FAQ
Reed Sensor selection FAQ
Answers are shown on-page to match the structured FAQ data and help engineers prepare datasheet review or RFQ requests.
How do I choose a Reed Sensor model?
Start from the application requirement, then compare Sensing mode, Output, Housing, Cable / connector, Environment. Open the model detail page and PDF datasheet before confirming the final ordering code.
Where can I find individual datasheets for this product family?
Each representative model card links to its own detail page and PDF datasheet. For production projects, submit an RFQ so voltage, current, mounting and compliance requirements can be confirmed.
What information should be included in an RFQ?
Include working voltage, current, load type, contact or output form, coil or control voltage, mounting style, environment, validation quantity and expected production volume.
