The screwdriver slot is aligned with the wiper within 10. Special shafts are available, in accordance to drawings supplied by customers. We recommend that customers should not machine shafts, in order to avoid damage. Bending or torsion of terminals should also be avoided. The typical linearity of linear variation law potentiometers is 5 %. Guaranteed linearity on request. Consult VISHAY.
