Matelec 9004 Series Oil & Chemical-Resistant NRB Float Switches for Heavy-Duty Liquid Level Control

The Matelec 9004 Series float switches are built for demanding liquid level control applications where durability, chemical resistance, and reliability are essential. Featuring a smooth, heavy-duty polypropylene housing and a nitrile rubber blend (NRB) cable, these switches are resistant to oils, chemicals, and foreign material build-up. Their unique ‘sliding detent action’ minimises wave-induced oscillation, ensuring highly consistent switching level accuracy.

With a high current rating of up to 10 A, the 9004 Series is ideal for heavier duty pump control, level monitoring, and automation tasks in industrial, wastewater, and chemical handling environments.

FEATURES

• Smooth, robust polypropylene housing reduces adhesion of solids and debris
• Oil and chemical-resistant nitrile rubber blend cable for harsh environments
• ‘Sliding detent action’ prevents wave-induced oscillation for precise level control
• High 10 A current rating for heavy-duty applications
• Corrosion-resistant IP68 protection to a depth of 9 m
• Adjustable switching differential via cable weight positioning
