This Hengstler document is a set of catalog pages for Incremental Encoders, titled Shaft Encoders 2001. It explains the basic operating principle: a line-coded disc interrupts an infra red light ray, and the resulting signal is available at the encoder output. It also lists typical applications such as franking machines, door closing devices for trains, desktop robots and plotters.
The catalog presents special features and mechanical and electrical technical data for models including RI 30, RI 36, RI 58, RI 59, RX 70-TI, RI 36-H, RI 58-H, RI 58-D, RI 76 TD, RI 32 and RI 38. Separate sections cover incremental encoders with hollow shaft and economy types.
| Number of pulses (RI 58) | 1 ... 10,000 |
|---|---|
| Output | RS 422/push-pull |
| Supply voltage (SELV) | 5 VDC/10...30 VDC |
| Max. pulse frequency | 300 kHz (RS 422); 200 kHz (push-pull) |
| Protection class | up to IP 67 |
| Operating temperature (RI 58) | -10...+70 °C (RI 58-O); -25...+100 °C (RI 58-T) |
| Hollow shaft diameter (RI 76 TD) | 15 to 42 mm |
The document lists franking machines, door closing devices for trains, desktop robots, lens grinding machines, plotters and testing machines for optical waveguides, among others.
The listed models use 5 VDC or 10...30 VDC as SELV supply voltage.
The maximum pulse frequency is 300 kHz for RS 422 output and 200 kHz for push-pull output.
The RI 58 is listed with protection class 65/64 and 67/67.
