Optical Level Switches designed for harsh environments with extremes in temperature, pressure, vibration and shock. Sealed to meet IP67 in a stainless steel housing :

• Phototransistor trigger
• Digital output, solid-state technology
• Output : TTL 200 mA, sinking
• Fast response

These compact optical switches incorporate a phototransistor that provides a digital output indicating the presence or absence of liquid. The sensor tip houses the phototransistor. The refractive index is changed when covered by liquid, thus indicating the level.

There are several wetted materials and operating ranges to choose from within Madison's optical switch series, including high-temperature performance options.

As with all Madison products, engineered configurations for your unique requirements can be quoted.
