PRODUCTSPRESSURE SWITCH
Gap-Sensing Pressure Switch (Model No. S51-1_1)
Model No. S51-1_1
- Small and compact
- The Ø1.0- or Ø1.5-mm nozzle is used for detection.
Detection in narrow places is also covered. - The indicator lamp is included as standard. (The lamp turns on when detection is ON.)
- Gap-sensing can be checked visually.
- These models are connected in series (using a manifold).
- Even a system for multi-point detection can be made compact, saving space.
- A pressure gauge to detect back pressure can be installed.
