BERNSTEIN
Magnetic sensors with Reed technology
Reed technology:
The operation is based on a Reed-relay which consists of a sensitive blades encapsulated in a small glass tube. In the presence of a magnetic field, the blades become magnetically attracted and the circuit is closed. When the magnetic field is removed, the blades return to their default state. Bistable-versions stay in activated once the magnetic field is removed and resets when the magnetic field is brought back again.
Hall technology:
Hall techonology is based on the alteration of a magnetic flux. Electronic Hall sensor has great advantages such as high switching frequency, reliability, immunity to vibration, stability, long service life, high accuracy, fast respond time and long sensing distances. Hall sensors are well applicable for example in rotational speed monitoring and measuring. Detection distance up to 60mm.
Electrical protection:
Reed-relays must be electrically well protected due to their small size and construction. For applications with inductive loads, see the diagram below.
When using AC-loads, use a varsistor or a RC-element in parallel circuit.
- Reed contact sensor
- Long detecting distance
- Dirt, dust or moisture does not affect the operation
- Detection also through non-magnetic material
