INTRODUCTION

The Neo-Dyn® Model 100P Enclosure 7 Adjustable Pressure
Switch is an explosion-proof, electromechanical pressure switch
designed for a wide range of applications in pneumatic and
hydraulic systems up to 3,000 psig. The most common wetted
materials include a polyimide (Kapton) sensing diaphragm, nitrile
O-ring, and aluminum alloy or corrosion resistant steel (CRES)
pressure port. CRES diaphragms and all-welded construction are
also available for corrosive pressure media.

Setpoint adjustments are easily made through the adjustable range
of the Pressure Switch using either the increasing or decreasing

handles. These handles are accessed by removing the unit’s front

cover.
Model 100P Enclosure 7 may be ordered to switch 125 to 600

VAC, or 28 to 125 VDC, with currents from microamperes to 15
amperes.
