In the fields of industrial equipment, rail transit, communication base stations, marine equipment, etc., connectors undertake the key tasks of signal and power transmission.
However, these connectors often face harsh environments such as high and low temperature cycling, moisture immersion, vibration impact, and dust intrusion. Once the sealing and insulation performance fails, it may lead to equipment communication interruption or control failure.
Connector sealing
Especially under the requirement of IP68 protection level, connectors must still work stably in long-term water immersion and high humidity environments, which poses higher challenges for encapsulation materials:
Low viscosity: Ensure that the sealing material can fully penetrate the fine gaps inside the connector, avoiding bubbles and voids.
Resistant to high and low temperature impacts: -40 ℃ cold to 150 ℃ high temperature alternating cycle without damage.
Flame retardant safety: meets V-0 flame retardant rating to prevent electrical fire hazards.
Long term water-resistant soaking: Ensure stable sealing performance without deterioration.
