Their small footprint makes them especially valuable in miniaturized systems such as semiconductor testing equipment and medical devices, while also serving critical roles in telecommunications, security, automotive, appliances, and industrial automation.

Specialized relays for ultra-high voltage applications exceeding 1.5kV. Ideal for isolation in medical devices, renewable energy systems, and advanced industrial equipment.

Magnetic Float NBR or Nitrile Butadiene Rubber floats have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Magnetic Float PA or Polyamide floats are made of nylon, have a very high strength-to-weight ratio making them shock and abrasion resistant, enduring a pressure of 5 bar (73 PSI or 0.5 MPa). Magnetic Float PP (polypropylene) are rugged, highly resistant to many chemical solvents, bases and acids and have a water absorption of only 0.1%. V2A Floats are made of rust-proof stainless steel and are resistant to high temperatures making them ideal for the Food & Beverage industry among others.
