The TMA / TMF Pressure Switch from Anfield Sensors is a rugged, high-performance pressure switch engineered for demanding hydraulic and pneumatic applications. Available in both field-adjustable (TMA) and factory preset (TMF) configurations, it offers reliable switching across a wide pressure range of 15 to 5,000 psi (1 to 345 bar), making it ideal for industrial equipment, mobile machinery, fluid power systems, and process control applications.

Built with a proven piston/diaphragm sensing design, the TMA / TMF delivers exceptional accuracy, long service life, and excellent resistance to pressure spikes, with a maximum overpressure rating of 9,000 psi (620 bar). Snap-action microswitch technology ensures dependable switching performance, while multiple electrical terminations, pressure ports, diaphragm materials, and housing options allow the switch to be configured for virtually any application.

Designed for harsh operating environments, the TMA / TMF offers high ingress protection options, durable brass or stainless steel housings, and compatibility with a variety of hydraulic oils, water, air, and compatible fluids. Whether protecting critical equipment, monitoring system pressure, or controlling hydraulic circuits, the TMA / TMF provides dependable performance where reliability matters most.
