Anfield SMA-6-4M-C-HC Pressure Switch

Anfield's SMA-6-4M-C-HC is a high‑pressure pressure switch in the SMA family, designed to monitor hydraulic and pneumatic systems and actuate electrical circuits when a preset pressure is reached. The unit covers 300 to 1200 psi (about 21 to 83 bar) and uses a 1/4‑inch NPT connection on the switch body for straightforward installation into standard lines. The SMA family offers factory preset or field‑adjustable set points, providing on‑site tuning to exact system requirements. This model is built for rugged industrial environments and suits safety interlocks, alarms, and automated control loops in hydraulic or pneumatic circuits. For harsher environments, CA or CS variants provide IP67‑rated protection, expanding suitability to washdown or dusty areas. The SMA/SMF high‑pressure switches are widely used across industrial applications, delivering reliable pressure‑switching performance in compact packages.
