CHAPTER

1

INTRODUCTION

The Neo-Dyn® Enclosure 3X Switches described in this manual are weather-proof,
electromechanical sensing devices designed for a wide range of applications in pneumatic
and hydraulic systems up to 10,000 psig. Models 100P, 101P, 110P, 200P, and 201P are
gauge pressure switches, Model 180P is a vacuum switch, and Model 160P is a differential
pressure switch.

The most common wetted materials of these pressure and vacuum switches include a
polyimide (Kapton) sensing diaphragm, nitrile O-ring, and aluminum alloy or corrosion
resistant steel (CRES) pressure port. CRES diaphragms and all-welded constructions are
also available in some models for corrosive pressure media and are standard on the
temperature switches.

Setpoint adjustments are easily made through the adjustable range by turning an
adjustment nut located inside the housing. On Models 101P and 201P this adjustment is
external.

The standard configuration of these switches will switch up to 15 amp at up to 250 VAC
in a single-pole configuration, and up to 11 amp at up to 250 VAC in a double-pole
configuration. When ordered with M Option, the switch is rated for currents to one amp,
but its bifurcated gold contacts will reliably switch currents in the milliampere and
microampere ranges.

These switches have CE Mark, and they all have weatherproof enclosures with IP66
ingress protection and that meet the requirements of NEMA 3. 3R, 3S, 4, 4X and 13. The
internal switch elements are UL and CSA recognized components.

OTHER CONFIGURATIONS

WARNING The models described in this manual are also available in special and factory-set

configurations. For these units, follow the installation and operating instructions herein,
except adhere to the pressure and electrical limits marked on the units.

Enclosure 3X Pressure Switches Page 2

Installation of these Neo-Dyn® Enclosure 3X pressure switches is straightforward.
However, they must be installed by a qualified electrician, in compliance with all local
and national electrical codes.

WARNING Electrical hazard
WARNING Do not make electrical connections while power is on.
WARNING Always check for multiple circuits.
WARNING Always make sure grounding is adequate.
WARNING Do not remove switch while under pressure.

MOUNTING

CHAPTER

2

INSTALLATION

The Pressure Switch can be mounted directly to the process connection if there is no
significant vibration and the fluid lines are capable of supporting the weight. It can also
be attached to a flat surface, such as a wall or panel, using .250 in. diameter or M6
socket-head cap screws through the mounting holes that are accessed by removing the
housing cover; allow .5 in. (12.7 mm) screw length above the mounting surface. These
holes are located on two corners of a 2.72 inch (6.91 cm) square, or 3.85 inches (9.77 cm)
apart on a 45° diagonal. Do not over tighten the screws when replacing the cover.

Note that on certain models and ranges the housing of the pressure fitting has a large
outside diameter that extends below the mounting surface, requiring either a cutout in that
surface, or having the pressure fitting overhang an edge. These models are 100P and
101P, Range 1; 110P; 142P; 152P; 160P; and 180P
