CHAPTER

INTRODUCTION

The Neo-Dyn® Enclosure 3X Temperature 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 1500 psig. Model 100T has its
temperature sensor mounted on its case, while Model 100TC has a remote sensor,
mounted at the end of a flexible capillary.

The wetted materials of both models include a welded corrosion-resistant steel (CRES)
temperature sensor. Model 100T has a Teflon seal, while Model 100TC has a graphite­filled non-asbestos packing.

Setpoint adjustments are easily made through the adjustable range by turning an
adjustment nut located inside the housing.

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 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.
