G1/2'' brass insertion paddle flow switch DN 50-150 100 bar
Its G 1/2" male thread screws into a socket on a DN 50, 80, 100 or 150 pipe. The adjustable switch point depends on the pipe size: with water about 68 to 90 l/min in DN 50, 700 to 917 l/min in DN 150. 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.
