Hall
Sensors
FH-301 & FH-500 Series Hall sensors are miniature solid-state Hall
effect
magnetic field sensing devices. The FH-500 series uses a lead
strip which is composed of printed circuit leads encased in DuPont’s Kapton
and
terminating in contacts on .075” centers. This flexible and tough lead
strip
can be made in a variety of configurations. The model FH-301 has conventional wire leads.
Mechanical Specifications
Electrical Specifications
Leads: AWG 34 copper with polyurethane insulation
(FH-301).
a.Polarity: With field direction (+B) as shown and Ic entering
the Ic (+) terminal, the positive Hall voltage will appear at the
VH (+) terminal.
b.Note: Unless otherwise specified, all specifications apply
at nominal control current with T= 25ºC. Heat sinking can
enhance performance in several respects.
