The original Magnasphere switch design. Robust all metal construction is highly
resistant to magnetic tamper and defeat, and permanent contact welding from
power surges. Can also be used as a close tolerance ferrous metal proximity
sensor (no magnet actuator required).

GENERAL CHARACTERISTICS & INFORMATION
Construction:
Non-Ferrous Metal Housing,
Compression Seal Hermetically Sealed,
Protective Gas Atmosphere, Precious
Metal Plated Spherical Magnet Contact.
Soldering Guidelines:
600º F (315º C)
Temperature iron for 5 sec. (max.). Do
not solder within 1/8” (3 mm) of glass
seal. Lead pins precious metal plated
for enhanced solderability.
Termination Polarity Guidelines:
Polarity
selection is non-critical, though some
life gain may be realized by center pin
as cathode on logic loads, but center
pin as anode on larger loads.
Lead Wire Cutting / Bending Guidelines:
Cut length has no effect on magnetic
OP/REL values. Shearing action type
cutters are recommended, but end nippers
and side cutters are NOT recommended.
Metal style seals are extraordinarily
rugged, but the bending of unsupported
lead wire pins adjacent to the glass seal
is not recommended (i.e. when bending
use the support of some type of parallel
jaws spaced away from the glass seal to
grip the lead wire pins while bending
the pins’ free ends, so no bending
strains are imposed on the glass seal.
Other Comments:
Ferromagnetic mate-
rials and strong Electromagnetic devices
proximate to the switch or its actuator
magnet may adversely affect expected
OP/REL switching values. Experimen-
tation is recommended to investigate
areas of concern.
