SICK DKS40-E5J00300 Incremental Encoder 300 PPR 8 mm shaft

SKU CH-TEXG-D5SZ1

Solid-shaft incremental encoder delivering 300 pulses per revolution on an 8 mm shaft with HTL push-pull output and a 0.5 m universal cable

  • Precise positioning with 300 pulses per revolution
  • Reliable HTL push-pull output from 10 V to 30 V
  • Fast 40 ms initialization for quick system start
  • Robust 8 mm solid shaft rated for 6,000 rpm
  • Long-life bearings designed for 2 x 10^9 revolutions

SICK DKS40 Incremental Encoder

The SICK DKS40-E5J00300 is an incremental encoder built for motion-control tasks that need precise position feedback. It delivers 300 pulses per revolution with a 90-degree electric measuring step and an initialization time of 40 ms. The solid 8 mm x 13 mm shaft and face-mount flange suit direct coupling to motor or gearbox shafts in industrial automation.

10–30 V HTL interface and 0.5 m cable

The encoder operates on a 10 V to 30 V HTL push-pull supply, drawing 40 mA without load, and connects through an 8-wire universal cable 0.5 m long. The single reference signal is positioned at 90 degrees electric and logically gated with channels A and B. An output frequency of 200 kHz supports high-speed counting without extra signal conditioning hardware.

Low torque and 600-year MTTFd

Start-up torque is 0.6 Ncm and operating torque 0.4 Ncm at 20 °C, keeping mechanical drag minimal at speeds up to 6,000 rpm. Rotor inertia is 6 gcm2 and bearing lifetime is rated at 2 x 10^9 revolutions. The unit weighs 0.18 kg and carries a mean time to dangerous failure of 600 years per EN ISO 13849-1.

Questions about this item

What is the maximum continuous speed the 8 mm shaft can handle before mechanical limits are reached?

The solid shaft is rated for 6,000 U/min continuous operation, with a bearing lifetime of 2 x 10^9 revolutions under normal load.

How much heat and current does the HTL push-pull interface draw during all-day operation?

Operating current is 40 mA without load from a 10 V...30 V supply; operating torque is 0.4 Ncm at +20 °C, indicating low heat rise.

Which mounting flange and shaft fit does the encoder need on the existing motor?

It uses a face-mount flange with an 8 mm x 13 mm solid shaft, so the motor must match that shaft diameter and flange pattern.
