HERION Electro-Mechanical Pressure Switch
Catalog Number (Bestell-Nr.): 0801573
Manufacturer: HERION (Made in Germany)
1. General Description
The Herion 0801573 is a robust, electromechanical pressure switch designed for pneumatic and hydraulic applications. It converts a pneumatic pressure signal into an electrical switching signal.
This device features a user-adjustable pressure switching point between 0.3 and 6 bar. When the system pressure reaches the set value, the internal micro-switch actuates, either closing or opening an electrical circuit (depending on wiring). Its heavy-duty metal housing makes it suitable for harsh industrial environments.

-
Common (COM): Power Input.
-
Normally Closed (NC): Circuit is closed when pressure is below the setpoint.
-
Normally Open (NO): Circuit closes when pressure reaches the setpoint.
Note on Voltage: Unlike many modern switches rated for 250V, this specific model is clearly marked for Max 48V. Do not use on 110V or 220V mains voltage.
