CHAPTER

INTRODUCTION

The Neo-Dyn® Enclosure 6N Temperature Switches described in
this manual are weather and explosion-proof, electromechanical
sensing devices designed for a wide range of applications in
pneumatic and hydraulic systems up to 1500 psig, and for use in
Zone 1 Potentially Explosive Atmospheres (Division 1 hazardo us
locations). 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 graphite-filled
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 11 amp
at 125 or 250 VAC, 5 amp resistive at 28 VDC, or 0.5 amp
resistive at 125 VDC. 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 electrical
subassemblies are listed by Underwrites Laboratories, CSA
International, Factory Mutual and ATEX.
