STG offers a wide range of reed switches with a glass tube length from 7 to 50 mm. The capacity range covers switching capacities up to 120 W/VA, switching voltages of almost 0 V to 10 KV AC/DC and switching currents of 0 to 3 A AC/DC. 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. In General:For all Reed Switches the standard pull-in sensitivity is given in the table. |
Order example:
For example: |
2203.1523.090 is an 1523 ReedSwitch, 2201.1917.065 is an 1917 Reed Switch, |
All Reed Switches are available in a normally closed or bistable version.
The given pull-in sensitivity of the Reed Switch has a test equipment tolerance of ± 2 AT.
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.
