The BML is a non-contact, incremental displacement feedback system
consisting of a sensor head and a magnetic tape. The system is available in
several variants: with position signal function only, with additional reference
point function and/or with limit switch function. All functions are implemented
by means of magnetic sensing. The reference position is integrated in the
tape, and limit switches can be attached at any desired position.
The following table show the functional variants with their possibilities.
