Anfield SPF-10R-4G-C79FL-1 Pressure Switch Sensor

Anfield SPF-10R-4G-C79FL-1 Pressure Switch Sensor is a compact, field‑adjustable low‑pressure switch from Anfield’s SPF/SPA family that activates or deactivates a circuit when pneumatic or light hydraulic pressure reaches its preset threshold. It uses a snap‑action micro switch in a sealed body for reliable operation in rugged environments, with an adjustable setpoint that can be tailored to the application. The model code encodes key options: 4G denotes a 1/4 BSPP (G1/4) male process connection, while FL indicates flying‑lead termination with 18 inches of 18 AWG conductors, and the -1 variant aligns with the SPF family’s standard contact/configuration. SPF/SP A line offers multiple range options across models, including roughly 7–21 psi (0.5–1.5 bar), 15–35 psi (1.0–2.4 bar), and 30–100 psi (2.1–6.9 bar), enabling selection for rising or falling pressure as needed. For challenging environments, IP67 protective covers are available for both factory‑set and adjustable variants (CS for factory‑set, CA for adjustable switches), safeguarding the sensing element and wiring. Typical applications encompass industrial automation and machinery that require precise low‑pressure monitoring, such as pneumatic control loops, filtration or safety/alarm circuits, and water or mild hydraulic systems where space is at a premium. With its small footprint, configurable setpoints, and diverse termination options, the SPF series is designed to deliver dependable threshold switching in compact packages.
