G1'' stainless variable area flow switch water 20-60 l/min 300 bar
Closes a normally open contact at an adjustable water flow of 20 to 60 l/min. The potential-free reed contact carries no voltage of its own, so it can be wired directly to a PLC (programmable logic controller) input. It switches max. 100 VA, about 0.4 A at 250 V AC; valve or relay coils cause high switch-on currents, so add a contact protection relay (not included). The float is calibrated for water and water-based liquids. The 1.4571 stainless steel body with female thread is rated to 300 bar (≈4350 psi) and +120 °C (≈248 °F).
