Sensors for Air Cylinders

Features

Sensors for Air Cylinders detect the movement of magnetic field which is emitted from a magnet mounted on air cylinder piston. These sensors are capable of stable and high precision operations because of having a operatong point on steep area of the aperating curve. N-pole and S-pole sensors shall be used in combination.


・No sensor protrusion from cylinder case.
・Because the sensors have a long sensing length, the operating point can be taken even in the middle of the stroke.
・With the bounce time as 5μsec.,capable of accurate position signaling even working in high speed cylinder.

Air cylinder sensors are activated / deactivated by sensing the magnetism of a ring magnet installed in a cylinder piston. Since conventional sensor pick up the intensity of the magnetism regardless of the magnetic direction, the operating curve takes a chevron pattern with the magnet center at the peaking point as shown in figure 1. Because the operating points of such sensors are on the gentle slopes of operating curves, a stroke of 5mm or shorter is hard to be detected, which makes a long, stable operation difficult.

 

With an air cylinder sensors employing Hall Effect IC we offer, the operating curve, as shown in figure 2, takes a very different shape from that of a conventional sensors, because a Hall Effect IC switch picks up only the magnetism vertical against the sensing face. The operating points being on the steep slopes of the operating curves allows a Hall Effect IC switch to detect a small stroke without fail, and to perform stable operation for a long time. In a normal use operation, both N-pole and S-pole sensors will be used in combination.
