The PLS Series from Icon Process Controls offers a simple, economical solution for high or low liquid level detection in chemical and industrial tanks. These compact plastic level switches are designed for reliability, easy installation, and versatility across a wide range of clean liquid applications.

Each PLS switch features a hermetically sealed reed switch actuated by internal magnets embedded within the float. This magnetically triggered mechanism provides dependable switching with no external power required. The switch action can be easily reversed by flipping the float, allowing for normally open or closed operation based on your control requirements.

Ideal for integration into small monitoring systems or alarms, PLS switches are compatible with solid-state electronics and can interface with relays for higher-current tasks such as pump or valve actuation. These switches are panel-mounted through the tank wall and can be installed either internally (vertical orientation) or externally using optional fittings.
