Absolute linear encoder SHG-A series

SSIserial5 VDC

SSI (Synchronous Serial Interface) is a patented absolute encoder protocol invented by Max Stegmann GmbH. The transfer of position data is much faster than RS232 or RS485, making this protocol ideal for closed loop motion control. There are several variations of SSI currently available. Developed to meet a wide range of feedback applications, these absolute linear encoders provide a true absolute position immediately upon power-up. The encoder does not use batteries or static memory to retain the positional data. True position can be reacquired once power is applied, regardless of duration or power-off movements.
