Electrical Components

With the proliferation of electronic controls and development of autonomous and electric vehicles, there are more connectors and sensors in a vehicle than ever before. Each connection is a potential failure point which can be fatal in safety critical applications. Other failures can significantly impact the quality of your vehicle and result in recall claims.

Specialty lubricants for connectors and sensors ensure long lasting connections to improve the reliability of your automotive systems.

Connector lubricants are used to prevent wear, environmental corrosion. They are also very effective at preventing fretting corrosion, the result of micro-motions between contacts caused by vibration and thermal changes within the connector housing. By reducing the formation of metal oxide at the mated interface, connector greases extend contact life and keep resistance low.

High insertion force has become a major assembly challenge. Mating multi-pin connectors, sometimes in hard to reach locations, often requires significant force – creating the potential for incomplete mating, as well as repetitive-motion injuries for assembly workers. Synthetic based lubricants have been proven to reduce high insertion forces – without unacceptable increases in resistance.

NyoGel® 760G is the industry leading connector grease trusted and approved by leading OEMs for a variety of connectors including:

  • Seats
  • Doors and Windows
  • Tail lights
  • Trailer Tows
  • Dashboard Switches
  • And more.

The accuracy and operating life of automotive sensors is directly related to the quality of the lubricant used on both sensitive electrical and mechanical components. To meet a broad range of design needs, Nye offers light, low-shear sensor greases for very low power applications; lubricants with exceptional film strength to accommodate heat generated by resistance; and unique underhood sensor lubricants that withstand years of vibration, thermal cycling, temperature extremes, as well as salt spray, sand, road grit, and underhood fluids.

When electromechanical sensors or potentiometers break contact, signal is lost. To ensure continuous contact, choose a low-viscosity fluorinated lubricant. A more viscous lubricant may cause the contact to hydroplane, instead of remaining in contact with the resistor.

Designed to meet the 3X life standard, Nye switch lubricants are available for tin, copper, brass, and noble metal contacts. Tailored to low, medium, or high current switches and formulated for light, medium or heavy loads, these lubricants guard against millivolt drop, open circuit resistance problems, and "-40 °C contact bounce." Underhood, they withstand thermal cycling and temperature extremes, from –90 to 250 °C and resist humidity, dust, water, salt water, fuel, and underhood fluids. For the mechanical parts of a switch, Nye's family of damping greases provide an economical way to control the sound and feel. Air conditioning and climate control systems rely upon a series of motorized vents to route airflow for the comfort of the driver and passenger. Greases for this application should be formulated specifically to work with plastic gears and offer reliable performance at low temperatures.
