Pressure and Vacuum switches features • Gasketed, Die Cast Aluminum Enclosure with Epoxy Coating • SPDT Switch Output • Adjustable Deadband Option • Sealed, Isolated Metal Bellows Sensors • Adjustable Pressure Ranges: 30 ”Hg Vac to 6000 psi (-1 to 414 bar) UNITED ELECTRIC CONTROLS

The J6 is a reliable, sensitive pressure switch, originally designed for instrument air applications in process plants. Its compact design and combination of set-point sensitivity and narrow or optional adjustable deadband, offers cost-saving solutions for a variety of applications. The J6 is ideally suited for a wide range of industrial processes such as alarm/shutdown and low/high service pressures. OEMs also utilize the J6 in machinery and equipment for threshold protection. • Optional ATEX or GOST intrinsic safety compliance • Designed to meet Enclosure Type 4X • SPDT switch output •...

RECOMMENDED PRACTICES AND WARNINGS United Electric Controls Company recommends careful consideration of the following factors when specifying and installing UE pressure and temperature units. Before installing a unit, the Installation and Maintenance instructions provided with unit must be read and understood. • To avoid damaging unit, proof pressure and maximum temperature limits stated in literature and on nameplates must never be exceeded, even by surges in the system. Operation of the unit up to maximum pressure or temperature is acceptable on a limited basis (e.g., start-up, testing)...
