Product Specification

LLHPA650L1 High Performance Liquid Level Switches General Description
The LLHP range of liquid level switches offer larger mounting threads and robust stainless steel housings that can survive in aggressive environments.

The microcontroller based sensor is solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.

LLHPA650L1 High Performance Liquid Level Switches Features
• Liquid level switches that can detect almost any liquid type; oil or water based
• Large load output; high switching currents
• Choice of threads and terminal connections

LLHPA650L1 High Performance Liquid Level Switches Benefits

• Robust stainless steel housing
• Suitable for use within aggressive environments
• Larger mounting threads; standard or custom
