Optical encoder disc METIRIO® A1

METIRIO® A1, primed for plug and play applications, is equipped with cable, connector and mounting threads to ensure connectivity to closed loop motion systems. The Teflon cable enables vacuum applications and, in addition, its small static bending radius allows it to be used in very confined environments. The A1 version of the METIRIO® Readhead is terminated with a D-SUB 15 male connector, providing differential analog signals and I2C-Interface pins. An interpolation module can be also attached to the A1 plug. This module provides BiSS-C Interface and typical ABZ-signals.
