Функции
Incremental encoder (sin/cos 1 Vpp/RS422/HTL) with cable and connector, clamp flange or Synchro flange
Incremental encoders deliver a defined number of electrical pulses per revolution, which represent the measurement of the traveled distance or angle.
Incremental encoders operate on the principle of optoelectronic scanning of dividing discs with the transmitted light principle. The light source is a light emitting diode (LED). The light‑dark modulation generated as the encoder shaft rotates is picked up by photoelectronic elements. With an appropriate arrangement of the line pattern on the dividing disk connected to the shaft and the fixed aperture, the photoelectronic elements provide two trace signals A and B at 90° to one another, as well as a reference signal R. The encoder electronics amplify these signals and convert them into different output levels.
The following output levels are available:
- Analog signals sin/cos with 1 Vpp level
Better resolution can be achieved for encoders with sinusoidal signals by interpolating them in the higher‑level controller. - RS422 difference signals (TTL)
In the case of RS422 incremental encoders (TTL), the resolution can be improved by a factor of four by means of edge evaluation. - HTL (High Voltage Transistor Logic)
Encoders with HTL interfaces are designed for applications with digital inputs with 24 V levels.
