BERU Distributor Caps / Distributor Rotors — Reliable High Voltage Distribution

The task of the distributor caps and distributor rotors is to reliably distribute the ignition voltage over ignition cables and connectors to the spark plugs in the individual cylinders. BERU distributor caps and distributor rotors are manufactured from various materials and supplied with different forms of contacts and clamping arrangements — specially matched to the requirements of the individual ignition systems.


Distributor Caps

The distributor cap transmits the high voltage reliably and dependably to the ignition cable and the spark plug connectors on the spark plugs and the appropriate cylinder.

Technical Features

  • Made of highly insulating, high voltage resistant material (e.g. phenol, epoxy resin)
  • Depending on the version and requirement, lacquered inside and out as additional protection against condensed water and chemical effects
  • System-specific connector area with SAE, DIN, serrated teeth or M4 connectors
  • System-specific bracket, screw or spring clip attachment
  • With/without screening cover made of conductive plastic for returning interference to ground and to maintain electromagnetic compatibility (EMC) in accordance with manufacturers' requirements

Distributor Rotors

The BERU distributor rotor is a precision component that supplies the high voltage to the distributor cap in a precise rotary action.

Technical Features

  • Made of highly insulating, high voltage resistant material similar to the distributor caps
  • With/without 1 kOhm — 5 kOhm interference suppression resistor, depending on manufacturers' requirements
  • With/without speed governing, depending on manufacturers' requirements
  • System-specific push-fit or screw attachment
