Product Description

What this part is

The SIKA VHS40M01171U10 is a paddle-type magnetic flow switch from the SIKA VHS series: flow switches with pipe section, metal version with plug connector. It monitors volumetric flow in a pipe and switches a reed contact when flow reaches the setpoint. Type: Flow switch with pipe section.

Decoding the designation

VHS — SIKA flow switch with pipe section, metal version with plug connector.

40 — nominal diameter DN 40.

What these specs mean in practice

Operating Principle: A paddle carries a permanent magnet at its upper end; a reed contact sits above the magnet outside the flow. Flow deflects the paddle and actuates the reed contact. When flow stops, a second repelling magnet returns the paddle to its start position. The magnetic restoring force gives better long-term stability and lower sensitivity to pressure peaks than a leaf spring.

Nominal Diameter: DN 40. Series Pipe Section Materials: Brass CW617N or stainless steel 1.4571. Series Electrical Connections: Sensor plug M12 x 1 or plug connector DIN EN 175301-803-A.
