Schneider Electric 9016 GAW-1 NSNBC01 Industrial Relay

Schneider Electric's 9016GAW-1 NSNBC01 vacuum switch delivers precise vacuum-triggered control with a single changeover contact (1 normally open, 1 normally closed) for sensitive control applications. As part of the 9016G family, this diaphragm‑actuated switch switches when vacuum is reduced within a 0–28.7 inHg range, with an adjustable differential from 0.8–9 inHg to tailor the trigger point. A 1/4-18 NPTF pipe tap provides vacuum connections, and Buna‑N diaphragms contribute durability in challenging environments. Fluids controlled by the 9016GAW1 family include air, water, hydraulic oils, gases, and steam, depending on model configuration, making it versatile for vacuum lines and related equipment. The device carries a maximum positive pressure rating of 100 psi, allowing safe operation if line pressure rises above the vacuum setpoint. Typical applications span vacuum system control, pump and valve actuation, and process-line monitoring in manufacturing, packaging, and industrial automation, where precise vacuum thresholds govern safety and process reliability. The NSNBC01 designation identifies this specific variant within Schneider Electric’s 9016GAW1 lineup.
