Superseal contacten
Superseal contacts are used in waterproof connector systems designed for environments where moisture, dust, vibration and temperature variation are constant factors. In the truck workshop and trailer industry, these are exactly the conditions technicians work with on a daily basis. Whether the application involves wiring on a semi-trailer, lighting on a refrigerated body or electrical connections for hydraulic systems on a low-loader, Superseal contacts provide the mechanical and electrical reliability that these environments demand.
The Superseal system consists of two contact types that together form a complete waterproof connection: the pin contact and the socket contact. The pin contact, the male side of the connector, is crimped onto the wire and then inserted into the corresponding connector housing. The socket contact, the female side, works in exactly the same way and mates precisely with the pin contact. The combination of both contact types within a Superseal housing creates a connection that seals against splashing water, cleaning agents and condensation, all of which are regularly encountered during the operational life of trucks and trailers.
In trailer construction, Superseal contacts are used wherever loose connections or moisture ingress are unacceptable. This includes the wiring of ABS sensors, the connection of side marker lights along trailer walls, or the power supply for electrically operated tail lifts. In all these applications, the combination of a properly crimped connection and a watertight seal is what determines the service life of the installation. A poorly sealed connection on a trailer that is washed down daily or operated in wet conditions will lead to oxidation of the contact surface, increased contact resistance and eventual failure.
The contacts used in Superseal connectors are manufactured from tinned brass. Tin as a coating on brass provides resistance to oxidation and ensures stable electrical conductivity over the service life of the connection. This is relevant in the HGV workshop, where wiring components remain in service for years without replacement at every periodic inspection. A tinned contact surface retains its conductivity even after prolonged exposure to moisture and variable temperatures.
The contacts are suitable for wire cross-sections from 0.50 mm² to 1.5 mm². This range corresponds to the wire sizes commonly used for sensor wiring, lighting circuits and signal lines in truck and trailer installations. When crimping these contacts, using the correct crimp profile is essential. An improperly crimped connection that is not fully closed mechanically can compromise the waterproof integrity of the system and reduce the pull-out force of the connection. In the truck workshop, a calibrated crimping tool that supports the correct profile for Superseal contacts is therefore always used.
For trailer specialists and body builders who regularly construct new installations or repair existing wiring, working with Superseal contacts is a standard part of the trade. The contacts are supplied in quantities of 100, which suits the professional workshop environment where multiple connectors are assembled or replaced at the same time.
In the day-to-day practice of the truck and trailer sector, Superseal contacts allow technicians to make connections that withstand the demanding conditions of road transport, vehicle washing and changing weather. From rear light wiring on a standard trailer to sensor and control lines on an advanced refrigerated trailer, Superseal contacts are a functional and proven component of durable electrical installations in the transport industry.
