SOR 8V9-KK45-LL Pressure Switch

The SOR 8V9-KK45-LL is a Static-O-Ring pressure switch designed to monitor hydraulic or pneumatic systems and trigger electrical circuits when the set pressure is reached. It provides an adjustable switching range from 250 to 1800 psi, enabling precise control across a wide pressure spectrum, with over‑range protection up to 2500 psi to safeguard against pressure spikes. The device uses a K‑series SPDT switching element rated for 15 amps at 250 VAC, delivering reliable single‑pole, double‑throw signaling for control circuits. With a 6000 psi proof pressure rating, the 8V9-KK45-LL is built to endure static pressure without deformation, making it suitable for demanding industrial environments. Model 8V9-KK45-LL identifies this exact configuration within the SOR Static-O-Ring family, combining adjustable setpoint capability, robust electrical ratings, and solid pressure endurance for applications that require dependable pressure-triggered control.
