Sensor housing with integral mounting piece

摘要

A magnetic variation sensor (P) includes a magneto-electricity conversion element (1) for picking up variations in magnetic fields and converting the variations picked up into electric signals. A cable (4) is connected to the magneto-electricity conversion element (1). The magneto-electricity conversion element (1) and a portion of the cable (4) where the cable (4) is connected to the magneto-electricity conversion element (1) are embedded in a resin shell (5). A mounting piece (6) in the form of a metallic plate is secured to the shell (5) with its portion embedded in the shell (5). The portion of the mounting piece (6) embedded in the shell (5) is formed with a hole (12) through which the cable (4) passes. The hole (12) includes a radial recess (13) formed along the outer circumference of the hole (12). The recess (13) is filled with a portion of the resin forming the shell (5), whereby the resin filling the recess (13) serves to prevent the mounting piece (6) from rotating relative to the shell (5). The hole (12) has a cutout (14) extending to an outer edge of the mounting piece (6), whereby the cable (4) can be easily pushed into the hole (12) through the cutout (14).
