Product details
Overview
TMCS-28-5-10000-AT-01 from TRINAMIC Motion Control is an optical incremental encoder module designed for position and speed feedback on stepper and 3-phase PMSM/BLDC motors. It delivers 625 lines per rotation (40,000 counts per rotation), operates at 5 V supply with TTL-compatible differential ABN outputs, and supports up to 6000 RPM in precision motion control systems.
For engineers reviewing the TMCS-28-5-10000-AT-01 datasheet, TMCS-28-5-10000-AT-01 pinout, TMCS-28-5-10000-AT-01 application, or TMCS-28-5-10000-AT-01 equivalent, this page provides verified mechanical dimensions (28 mm × 28 mm × 18 mm), electrical interface details (9-pin Molex CLIK-MATE™ connector), resolution confirmation (40,000 cpr), and environmental ratings (–20 °C to +85 °C, IP40).
Technical Context
The TMCS-28-5-10000-AT-01 implements a high-resolution optical sensing architecture using a 625-line code wheel and dual-channel quadrature (A/B) plus index (Z) differential line-driver outputs. Its TTL-compatible ABN signals provide noise-immune position tracking with 10 ns rise/fall times and support for 1.5 MHz maximum output frequency.
Designed for direct motor shaft mounting, it features a 5 mm hollow shaft, axial/radial load ratings of 50 N / 80 N, and mechanical integration compatibility with standard stepper and BLDC motor flanges. The module requires no internal bearing and relies on motor shaft support per mechanical drawings in the hardware manual.

FAQ
What is the resolution of the TMCS-28-5-10000-AT-01 encoder?
The TMCS-28-5-10000-AT-01 provides 625 lines per rotation (lpr), resulting in 40,000 counts per rotation (cpr) when decoded with a quadrature counter. This resolution is fixed for this order code and confirmed in Table 2 of the TMCS-28 Hardware Manual Revision V1.80. The TMCS-28-5-10000-AT-01 achieves this using a high-density optical code wheel and differential line-driver outputs.
Does the TMCS-28-5-10000-AT-01 include a built-in bearing?
No, the TMCS-28-5-10000-AT-01 does not include an internal bearing. It is designed for direct mounting onto the motor shaft, relying on the motor's own bearing system for rotational support. This is explicitly stated in the hardware manual's revision history (Document Revision 1.40, 2019), which removed "Start Torque" from specifications because the encoder kit lacks internal bearings.
What connector type is required for the TMCS-28-5-10000-AT-01?
The TMCS-28-5-10000-AT-01 uses a 9-pin Molex CLIK-MATE™ connector: housing part number 5023800900 and crimp terminals 5023810000. Pin assignments are defined in Table 5 of the hardware manual, including VCC, GND, differential A/B/Z pairs, and shield. Using the specified connector ensures reliable signal integrity and mechanical retention.
Can the TMCS-28-5-10000-AT-01 operate at 3.3 V logic levels?
No, the TMCS-28-5-10000-AT-01 is specified for 4.5–5.5 V supply and produces TTL-compatible output voltages (VH ≥ 2.4 V, VL ≤ 0.4 V). It is not rated for 3.3 V operation. Interfacing with 3.3 V controllers requires external level-shifting circuitry or a compatible differential receiver that accepts 5 V inputs.
What is the maximum rotational speed supported by the TMCS-28-5-10000-AT-01?
The TMCS-28-5-10000-AT-01 supports up to 6000 RPM, as specified in Table 3 (Mechanical Specifications) of the hardware manual. This limit is determined by optical sensing bandwidth, mechanical stability, and signal integrity at high-frequency quadrature output - validated under rated temperature and load conditions.
