Speed Sensor / Namur Tachometer Installation Instructions
Many installations require a speed reference to be installed. SKF offers the Namur
tachometer to be employed where a speed signal is required. The Namur tacho is a
two-wire low power type (minimum operating level 5 V, no target output nominal 3 mA,
target output nominal 1 mA). The LED will flash whenever an event is sensed.
A custom mounting bracket is usually required (not included in the installation kit) to
hold the speed sensor firmly. The simplest bracket design uses a suitably sized portion
of ¼ inch thick Angle Plate. The sensor hole may be drilled and both jamb nuts employed
to hold sensor adjustment, or tap the bracket and use only one jamb nut to hold final
sensor adjustment.
Two holes are recommended for fasteners to hold the bracket firmly to machine
support or machine surface.
