Proximity Cycle Switches
The proximity cycle switches are magnetically operated single throw switches that sense the movement of the
divider valve piston when it is cycling. Each proximity cycle switch provides a signal that is used to monitor the
system. There are three (3) different types of switches available.
Solid State Proximity Switch:
Recommended for all applications including press and other demanding applications.
No moving parts. Capable of operation at cycle rates above 200 cycles per minute. Rated for 50 g shock and 20 g
vibration.
Reed Type Proximity Switch:
Can be used with oil applications only for MS, MH and MGO divider valves at
pressures up to 518 bar (7500 psi, 52 MPa) at cycle rates under 60 cycles per minute.
Field Sensitive Magnetic Proximity Switch:
Dry contact, ceramic magnet operated switch. Used at pressures that
do not exceed 242 bar (3500 psi, 24 MPa) at cycle rates up to 200 cycles per minute. Used in MS, MH, MX, MXP and
MGO divider valves. An explosion proof version for MS/MH divider valves is available.
Magnetic Operated Proximity Switch:
Not limited to valve size. Miniature snap-action switch is tripped by
attraction of internal magnet to the moving divider piston. Can be used at pressures up to 518 bar (7500 psi) at cycle
rates that do not exceed 150 cycles per minute.
