SICK 1072470 1024 PPR HTL 15 mm Hollow-Shaft Encoder

Technical Overview

The SICK DBS60E-THEK01024 is a 1,024-pulse-per-revolution incremental encoder with a 15 mm through hollow shaft and front clamping. Its two-sided slotted stator coupling fits a 63–83 mm screw-hole circle. Six HTL/push-pull channels provide A, B and reference Z signals with their inverted counterparts, and the 90° electrical reference is gated with A and B. The 10–27 V encoder uses a 1.5 m eight-wire PVC cable whose universal outlet permits radial or axial routing. Operating speed is 6,000 rpm, with a specified self-heating allowance. Aluminum housing and flange, a stainless steel shaft, and IP65 protection on housing and shaft sides support installation in rotary feedback systems.

Industrial Applications

1. Supplying speed feedback from a driven roller

A driven roller with a suitable 15 mm shaft can turn the through-hollow-shaft encoder while the two-sided stator coupling restrains the housing. An external counter derives rotational speed from the 1,024 pulses per revolution and elapsed time. Integration assesses the receiver’s HTL input, pulse-frequency capability, cable routing, operating speed and self-heating across the intended temperature range.

Problem Solved

A shaft-referenced pulse stream gives external speed control a rotational feedback value, helping regulate roller motion using the installed shaft as the mechanical reference.

2. Tracking relative feed travel in a web-handling station

A web-handling machine can couple the encoder to its feed-roll shaft and count A/B quadrature transitions in an external controller. The pulse count and direction provide a relative rotation reference that the machine converts to feed travel using its calibrated roll geometry. Commissioning evaluates material slip, receiver decoding, backlash and the actual mechanical installation before using that reference for feed-length control.

Problem Solved

Quadrature rotation feedback gives external feed control a relative travel and direction reference, helping coordinate repeated advances according to the calibrated feed-roll geometry.

3. Referencing one angular cycle of a rotary indexing mechanism

A rotary indexing mechanism can present the encoder’s Z reference to an external position controller once per revolution while A/B channels track motion between reference events. The documented reference is 90° electrical and logically gated with A and B. Startup establishes the required machine reference after the initialization interval, and mechanical alignment defines how the encoder index relates to the process position.

Problem Solved

The index signal supplies external control with a recurring angular-cycle reference, helping align incremental counts with the chosen mechanical position during rotary sequencing.
