Abstract:
PCT No. PCT/DE90/00567 Sec. 371 Date Mar. 16, 1992 Sec. 102(e) Date Mar. 16, 1992 PCT Filed Jul. 26, 1990 PCT Pub. No. WO91/04494 PCT Pub. Date Apr. 4, 1991.An RPM sensor for anti-lock and/or traction control systems of motor vehicles or for engine speed governing or gasoline or Diesel injection control. The RPM sensor has a housing, receiving electrical components, with a first housing part of plastic that is at least partly enveloped by a second housing part, produced in an injection molding process, likewise from plastic. To attain a moisture-proof, material bond between the two housing parts, a melting element of a plastic having a lower melting point than that of the plastic of the housing parts is disposed in a contact zone between the two housing parts. When the second housing part is formed, the melting element is heated above its melting point, and a material bond of the two housing parts is attained which protects the RPM sensor against moisture dirt, stress, etc.
