Contactless rail position sensor (RPS) 3502.3855


General information:

The contactless rail position sensor (RPS) 3502.3855 is purposed for constant current formation that is proportional to the throttle valve opening angle of the engine fuel injection system.

Application: automobiles MAZ, MAZ, BELAZ, PAZ, LiAZ, (YaMZ Euro-3) and others with diesel-fuel equipment manufactured by JSC "YAZDA".

The direction of rotation of the shaft (core) of the sensor from the initial position is counterclockwise from the side of the throttle valve (see the drawing below).

The sensor is produced in a single climatic design O2.1 in accordance with GOST 15150 for internal market and for export. On extent of protection against penetration of foreign bodies and water, the item meets design IP67 in accordance with EN 60529. An operating mode of the sensor is continuous nominal S1 in accordance with DSTU GOST 3940.

The high pressure fuel pump rail position sensor is installed directly on the housing of the high pressure fuel pump rail actuator actuator, where it is possible to install rail position sensors 3502.3855, 36.3855-20 or other similar ones, using standard fasteners.

The resource of this product is not limited to the mileage of the car. The warranty period of exploitation is 3 years from the date of commissioning or from the date of sale in retail commercial network. The warranty obligations of the manufacturer are valid during four years from the date of the item production. The date of production is marked on the case of the item housing.
