Displacement sensor
A displacement sensor includes first detection units that detect an amount of displacement of a same detection target, and are disposed such that detection surfaces for detecting the amount of displacement face each other; second detection units that detect an amount of displacement of the detection target which is the same as the detection target of the first detection units, and are disposed such that detection surfaces for detecting the amount of displacement face each other; and a lead frame including a main frame having one surface on which the first detection units are disposed and the other surface on which the second detection units are disposed, and a sub frame which is wire-bonded to electrodes provided on each detection surface of the first detection units and the pair of second detection units.
1. A displacement sensor comprising:
a pair of first detection units that detect an amount of displacement of a same detection target, and are disposed such that detection surfaces for detecting the amount of displacement face each other;
a pair of second detection units that detect an amount of displacement of the detection target which is the same as the detection target of the pair of first detection units, and are disposed such that detection surfaces for detecting the amount of displacement face each other; and
a lead frame that includes a main frame having one surface on which the pair of first detection units are disposed and the other surface on which the pair of second detection units are disposed, and a sub frame which is wire-bonded to electrodes which are provided on each detection surface of the pair of first detection units and the pair of second detection units.
2. The displacement sensor according to claim 1 , wherein the pair of first detection units and the pair of second detection units are disposed to face each other through the main frame.
