Henry Technologies S-9400A Liquid Level Switch 1/2" MPT 120 VAC

The Henry Technologies S-9400A Liquid Level Switch MPT is a sensing control component that monitors liquid presence and level conditions to support proper system operation within HVAC systems. It operates using optical detection technology that identifies whether liquid is present at the sensing point and triggers an electrical response accordingly. Installed in locations such as liquid receivers, suction accumulators, or compressor sections, it connects through a 1/2" MPT fitting and operates on a 120 VAC circuit. Its operation helps maintain correct fluid levels, prevents system faults, and supports reliable refrigeration and cooling performance.
