Cylinder on the use of magnetic switch characteristics and matters needing attention of magnetic switch cylinder switch two electrical signals and signal output signals, and the magnetic switch cylinder cylinder must use the non magnetic conductivity materials such as aluminum alloy and stainless steel, flying below the Wolf pneumatic for you to introduce the use of magnetic switch characteristics and matters needing attention the characteristics of the magnetic switch: switch the distance from the connected state to disconnect state piston movement, said the switch action range.
The piston to move in one direction after the switch to on state, then move in the opposite direction to make the switch to off state, of the distance between the two states, according to lag.
Using considerations: (1) switch of voltage, current and contact capacity should be within the prescribed scope.
(2) pay attention to the load transition electrical characteristics.
When choosing switch load, must also consider the transition electrical characteristics.
Transitional features include the switch from on to off when the instantaneous impulse voltage, and switching from closed to open when the impact of current.
Therefore, when using internal no protection circuit switch, must be in a setting impact placing signage at absorbing circuits.
(3) to use internal no protection circuit switch, when the wire length is greater than m, choke coil close switch should be installed.
(4) cannot be used in strong magnetic field.
When the switch cylinder used in strong magnetic field generates a misoperation.
Such as near the electric welding machine and the large capacity motor, must leave, make the cylinder switch more than lm.
If can't meet, should be carried out around the switch around or magnetic wave magnetic shielding.
