Product Description

Multi-turn Absolute Encoder With SSI Interface
GMA-S Series absolute encoder is an SSI multiturn absolute encoder. Synchronous Serial Interface (SSI) is point-to-point so slaves cannot be bussed together. SSI is uni-directional, data transmission being only from slave to master. It is therefore not possible for a master to send configuration data to a slave. Communication speeds are limited to 2 Mbits/sec.Many SSI devices implement double transmissions to improve communication integrity. The master compares the transmissions to detect errors. Parity checking (Appendix) further improves error detection.SSI is a relatively loose standard and many modified versions exist including the option for an incremental AqB or sin/cos interface. In this implementation absolute position is only read at startup.Housing Dia.:38,50,58mm; Solid/hollow Shaft Diameter:6,8,10mm;  Resolution: Single turn max.16bits;  Interface:SSI; Output Code: Binary, Gray, Gray Excess, BCD; Supply Voltage:5v,8-29v;
