All reed switches are available as normally closed, normally open or bistable versions.

All variations can be customized to meet individual customer requirements.

>> Life Expectancy:   The life expectancy of a Reed Switch is about 10⁵...10⁶ switching cycles with maximum power. With a low load the life expectancy can reach 5x10⁸ operations. The mechanical life expectancy can reach at least 10⁹ operations. Through the switching of inductive, capacitive and lamp loads, the life expectancy is considerably reduced due to exceeding the specified maximum current.

 >> In General:  For all Reed Switches the standard pull-in sensitivity is given in the table. Other pull-in sensitivities are available on request.

 >> Order example :   

For example:  2203.1523.090 is an 1523 ReedSwitch,

                      with pull-in sensitivity between 90-105AT (90+3*5AT);

                      2201.1917.065 is an 1917 Reed Switch,

                      with pull-in sensitivity between 65-70AT (65+1*5AT).

 >> Normally Closed and Bistable Reed Switches:  All Reed Switches are available in a normally closed or bistable version.

 >> Pull In Sensitivity Tolerance:  The given pull-in sensitivity of the Reed Switch has a test equipment tolerance of ± 2 AT.

 >> The materials  used for Reed Switch magnets are generally ALNICO (an aluminium nickel cobalt alloy), a ceramic (barium ferrite or another metal oxide) or rare earth magnets. Due to their specific magnetic characteristics, the types of magnets differ in shape: ALNICO magnets are bar magnets with a length/diameter ratio of 3/1 to 5/1; oxide magnets are generally disc or moulded magnets. Also important to note is the difference in temperature coefficient: ALNICO: 0.02 %/K, oxide: 0.2 %/K.
