Inexpensive proximity sensor with internal reed switch, that is turned on and off by change of magnetic field strength (vertical, horizontal or longitudinal movement of magnet).
Contact Forms:
 N.O.
N.O. Contact (Normally Open)
Contact which is normally open. It will be closed when magnetic field is applied.
N.C. Contact (Normally Closed)
Contact which is normally closed. It will be opened when magnetic field is applied.
|
Transfer Contact (Form "C")
Common contact (wiper) will transfer from N.C. to N.O. contact when magnetic field is applied.
Latching Contact
After being opened or closed by application of magnetic field, the contact will be held in this position (latched) even after removal of the magnetic field. Application of a magnetic field with reversed polarity will unlatch the contact.
