Device and system for detecting position
First Claim
1. A position detecting system comprising:
- a member including a first section comprising a magnetic body and a second section which is relatively displaced to said first section; and
a position detecting device, mounted on the second section, detecting relative position to the magnetic body, said position detecting device comprising;
a Hall IC which switches on/off electrical signal output depending on the relative position to the magnetic body; and
resin covering said Hall IC so as to position it inside said position detecting device;
wherein the first section is mounted such that the switching point of on/off of electrical signal output crosses the boundary of the magnetic pole after relative displacement.

Abstract
To provide a position sensor small enough to be contained in a groove formed in an air cylinder in which minimum stroke for fixing and differential travel are improved [MEANS FOR SOLVING PROBLEMS] The position sensor comprises a Hall IC (50) for turning an electric signal on/off according to the position relative to a magnet provided on the piston of an air cylinder, a resin (60) such as a polyamide resin molded to cover the Hall IC (50), a stainless steel frame (30) defining the orientation and position of the Hall IC (50) in the resin (60), a part (40) fixed to the frame (30) in order to pass a screw for fixing the position sensor (1) to the air cylinder, conductors (18, 20, 22) connected to terminals (24, 26, 28) of the Hall IC (50) by soldering, rubber insulators (12, 14, 16) covering the conductors (18, 20, 22), and a rubber sheath part (10) for bundling the insulators (12, 14, 16).
