SOR 4N3-KK4-N1-C1A-ZZ Pressure Switch, 2-25 PSI

SOR 4N3-KK4-N1-C1A-ZZ is a pressure switch designed for monitored pressure control in industrial systems. Adjustable 2-25 PSI switching supports setpoint-based electrical actuation as process pressure rises or falls. The configuration fits control, alarm, and shutdown workflows where discrete pressure status is required.

- Process pressure enters the pressure port and acts on the internal sensing element.
- Setpoint adjustment establishes the pressure threshold for switching behavior.
- When the threshold is reached, the internal mechanism changes electrical contact state through the attached lead wires.
- Discrete switching output enables pressure-based alarm, interlock, or control response.
- Proof and over range ratings support pressure exposure beyond the adjustable switching span.

- Adjustable pressure range: 2-25 PSI
- Over range: 750 PSI
- Proof pressure: 1000 PSI
- Electrical interface: attached flying leads
- Form factor: enclosed pressure switch with process connection and mounting base

- Process pressure alarm circuits
- Pressure-actuated control switching
- Equipment interlock and shutdown signaling
