End of Stroke Magnetic Principle Type
Proximity Switch
Reliable: Proximity type sensor never contacts cylinder
moving parts; eliminating wear and adjustments.
Positive Action: Multiple magnet design provides “snap
action.” Eliminates creep and false signals.
Versatile: Sealed stainless steel switch body can be used
with any operating uid and is impervious to most environmental
conditions.

Switch Options
Quick disconnect.
Explosion proof.
Sub sea, to 2000 feet depths.
Extra-long leads.
As shown in the sketches above, these
switches are magnetically operated. Dual
magnets provide a dependable “snap action”
for positive position sensing.
In the “unoperated” position, the magnet
assembly is attracted in the direction of the
arrow, causing a nely ground stainless steel
connecting rod to hold the contacts open.
In the “operated” position a ferrous part
(cushion or piston) enters the sensing area
and attracts the magnet assembly which
causes the rod to draw the contacts closed.
How to Order:
To order switches, enter a “9” in the Modied
eld of the cylinder model code. Describe the
modication in notes by specifying:
1
. Magnetic end of stroke switch
2. Installation in head, cap, or both ends
of the cylinder
3. Location in the head or cap (position #1,
2, 3, or 4) not occupied by a port or
mounting
