Single-turn Absolute Encoder A/345
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, Single-turn Absolute Encoder, SENSORS
El ELCIS 345 (A/345) es un encoder absoluto monovuelta óptico de 2 a 8 bits, con electrónica incorporada, apto para aplicaciones robóticas.
As an optical single-turn absolute encoder with LED source and phototransistors, the A/345 offers up to 256 steps per revolution (8 bits) in Gray, Excess, or custom code. The output is parallel, via a 1 m cable with radial or axial output, and the direction of rotation (CW or CCW) is selected at the time of ordering.
Tiene formato cuadrado de 45 mm y eje de acero inoxidable Ø4 h7 para 0,5 kg de carga radial/axial, resiste impactos de 50 G y vibraciones de 12 G, y trabaja entre 0 y +70 °C con protección IP64 en el lado del eje (IP65 en versión sellada).
- Resolution of 2 to 8 bits: until 256 steps per lap.
- Code Gray, Excess either personalized (bajo pedido).
- Direction of rotation CW either CCW to choose in the order.
- Impact resistance of 50 G (11 ms) already vibrations of 12 G (10–2000 Hz).
Technical Frequently Asked Questions
What resolutions does the A/345 offer?
In Gray code, 8, 16, 32, 64, 128 or 256 steps per revolution; in Excess, 180. Other resolutions available upon request.
How do you choose the direction of rotation of the A/345?
In the order code: leave the box empty for clockwise (CW) rotation or AR for counterclockwise (CCW). The direction of rotation is not switchable (up/down).
What connection and output stages does the A/345 support?
1 m cable (CV, IP65) with radial (R) or axial (–) output, and 10 mA open collector NPN stage, with parallel interface.
