Product Description

The HEDLAND Flow Switch: Piston (MPN H605B-005-F1) is a variable area flow switch for water with an aluminum housing and 1/2 in FNPT connections. It features an adjustable set point, a normally closed SPDT switch, and contact ratings of 10 A @ 250V AC and 0.5 A @ 125V DC.

Frequently Asked Questions

What is the HEDLAND H605B-005-F1 flow switch used for?

The HEDLAND H605B-005-F1 is a variable area flow switch for water. It monitors flow rates from 0.5 to 5 gpm in industrial piping systems, triggering an alarm or shutdown when flow deviates from the adjustable set point. Common applications include cooling water circuits, process water lines, and pump protection.

What are the specifications of the HEDLAND H605B-005-F1?

The HEDLAND H605B-005-F1 has an aluminum housing, 1/2 in FNPT connections, and a piston-actuated SPDT switch that is normally closed. Its adjustable set point covers 0.5 to 5 gpm. Contact ratings are 10 A @ 250V AC and 0.5 A @ 125V DC. The manufacturer part number is H605B-005-F1.
