SICK DFS60B-S4EC01024 Incremental Encoder

The DFS60B-S4EC01024 produces 1,024 pulses per revolution with HTL / push-pull outputs. Use the quadrature A/B signals for incremental movement and direction, and Z as the once-per-revolution reference. It does not retain an absolute multi-turn position through a power loss.

Pulses per revolution describe one signal cycle, not a universal controller count. A counter using four-edge quadrature decoding yields 4,096 counts/revolution at the listed 1,024-PPR setting. Match the counter’s input level, decoding mode and maximum input frequency to the encoder.

Signal frequency is PPR × rpm ÷ 60. At 1,024 PPR, the encoder’s 600 kHz output limit and 9,000 rpm mechanical ceiling together give 9,000 rpm before temperature and receiving-counter limits are applied.

M12 pins: 1 = /A, 2 = A, 3 = /B, 4 = B, 5 = /Z, 6 = Z, 7 = GND and 8 = +Us.

Use a counter or motion input designed for HTL/push-pull encoder signals at the selected supply. A standard digital input may lack the input frequency or signal processing required for rotary feedback.

Connect the 10 mm solid shaft to the machine shaft with a suitable coupling and support the machine shaft independently. Keep misalignment and external forces within the encoder’s radial and axial limits. Matching the 60 mm housing diameter alone does not establish a mechanical replacement.

The +100 °C ambient endpoint and 9,000 rpm mechanical limit are not simultaneous unrestricted operating ratings. Allow 3.3 K self-heating per 1,000 rpm in the operating-temperature budget, and apply the lower electrical frequency limit at the selected pulse count.
