G1'' brass variable area flow switch oil 20-60 l/min 250 bar
Closes a normally open contact at an adjustable oil 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). Viscosity compensation keeps the set point valid for oils from 30 to 600 cSt (centistokes). The nickel-plated brass body with female thread is rated to 250 bar (≈3630 psi) and +120 °C (≈248 °F).

Pros:
- Adjustable set point from 20 to 60 l/min
- Potential-free reed contact, no supply voltage needed
- One set point for oils from 30 to 600 cSt
- DIN plug connector (EN 175301-803)
- Any mounting position, preferably with upward flow
Cons:
- Contact protection relay (not included) needed for valve or relay coils
- 50 mm clearance from iron parts needed; not for strong magnetic or induction fields
- Not suitable for liquids with solid or magnetic particles
