Cylinder Control Unit
First Claim
1. A cylinder control unit, mountable on a cylinder, provided with a first and a second position detecting devices for specifying motion range of a piston in said cylinder wherein the first and the second position detecting devices respectively compriseHall IC switching on/off of output of electrical signal depending on relative position to a magnetic body placed so that moving direction of the piston crosses at right angle to the boundary of magnetic poles andresin covering said Hall IC while positioning it inside,Hall IC of the first position detecting device switches on/off of the output by magnetic force from a first magnetic pole andHall IC of the second position detecting device switches on/off of the output by magnetic force from a second magnetic pole.

Abstract
[Problem to be Solved] To specify motion range of piston 110 in air cylinder 100 with high accuracy.
[Means for Solving The Problem] Position detecting devices 1a and 1b respectively comprise
- Hall IC switching on/off of output of electrical signal depending on relative position to magnet 140 placed so that moving direction of piston 110 crosses at right angle to the boundary of magnetic poles and
- resin covering said Hall IC while positioning it inside,
- Hall IC of the first position detecting device switches on/off of the output by magnetic force from a first magnetic pole and
- Hall IC of the second position detecting device switches on/off of the output by magnetic force from a second magnetic pole.
The position detecting device 1b is mounted on the north pole side of the magnet 140 and the position detecting device 1a is mounted on the north pole side of the magnet 140.
