G1/4'' brass inline paddle flow switch 2.3-4.7 l/min 100 bar
Switches at an adjustable point of about 2.3 to 4.7 l/min of rising water flow. The flow deflects the paddle; the contact switches back at a lower flow, so it does not chatter. Sliding the switch unit sets the point and selects normally open (factory setting) or normally closed. The reed contact outside the medium switches max. 40 VA: enough for a PLC (programmable logic controller) input; pumps need a relay. The brass body with NBR seal is suitable for water, oils and coolants up to 100 bar (≈1450 psi) and +70 °C (≈158 °F). Replacement reed contact: M288B.
