The PS41 Series of pressure switches incorporates two design principles to achieve its performance characteristics. Those characteristics include repeatability of ۬ percent of the full set point range of 3 to 100 psi (0.2 to 7 bar) while delivering a 350 psi proof pressure. PS41 pressure switches are compact — the largest body is 1.25 in. in diameter. The miniature pressure switches are suitable where space and/or price are strong concerns. Typical applications include monitoring coolants in machine tools, transmissions in off-highway vehicles, and as back up to transducer-based monitoring systems. This series offers a large degree of configurability when specified. Brass or stainless body material; a choice of six pressure port sizes, three SPST, and SPDT switch circuits; and three set point ranges are available. The diaphragm can be specified in Viton, neoprene, or EPDM material. Electrical terminations include flying leads or cable with or without conduit connections, DIN and micro DIN connectors, and spade terminals. Operating temperatures for the series is -40° to +180°F. The electrical switch is rated to 5 A at 12/24 Vdc and 125/25 Vac. Optional gold contacts increase this rating to 10 A. The switches carry CE and UL approvals.
