The ABB 3HAC2493-1 is an ABB Robotics spare part identified as a “Control cable signal 7m” (a 7-meter signal/control cable assembly used in robotic and controller harnessing contexts).
In practice, this type of cable is part of the “nervous system” of an ABB robot cell: it carries sensitive control/feedback signals that must remain stable while surrounded by servo drives, switching power electronics, and mechanically dynamic routing. A correct, OEM-specified signal cable helps prevent the worst kind of production problem—intermittent faults that appear only under certain motions, temperatures, or EMI conditions.
Importantly, the ABB product data sheet style information available through industrial distribution channels provides concrete logistical and classification data for 3HAC2493-1, including net weight (0.76 kg) and net length (7000 mm), plus its placement within ABB’s Robotics categories such as Harness Cabling, Motor units and Gear units, and IRC5C Compact Controller Harness.

What “Control Cable Signal” Means in Robot Service
“Signal” cables in robotics are typically used for low-level control and measurement pathways—where signal integrity is more important than raw power delivery. In a robot cell, these cables commonly interface between:
-
controller-side harness points and robot-side subsystems
-
measurement/feedback circuits
-
auxiliary control signals used by application equipment
Aftermarket descriptions for this specific part number frequently label it as an SMB/encoder/resolver-style signal cable for ABB robots, reflecting how many signal cables in ABB ecosystems are used for feedback/measurement connectivity.
(That naming is not the official ABB catalog description, but it’s useful context for how the market recognizes the cable’s job.)

ABB Category Placement and Where It’s Used
ABB’s published product detail categorization places this part under Robotics application equipment and harnessing contexts, including:
-
Robot Positioners, Track Motion
-
Motor units and Gear units
-
IRC5C Compact Controller Harness
-
Harness Cabling, Harness Base and Frame
This matters for maintenance teams because it hints at the cable’s typical service role: it’s not a generic Ethernet patch lead or a random accessory; it’s a harness component meant to live inside ABB’s robotics integration structure, where length, connectorization, and shielding practices are assumed.
| ABB “Where Used” (as spare part for products) | Practical interpretation in a robot cell |
|---|---|
| Application Equipment & Accessories → Motor units and Gear units | Signal harnessing around motion units where feedback/control signals must remain clean |
| Application Equipment & Accessories → Robot Positioners, Track Motion | Harnessing used with external axes/positioners where motion + cable routing is demanding |
| Controllers → IRC5 → IRC5C Compact Controller | Controller-harness ecosystem; cable length and fit are typically standardized |
Why This Cable Matters for Uptime
A robot can have perfect mechanics and a healthy controller and still fail production targets because of a weak signal link. Signal cables often “age out” via bending fatigue near clamps, connector micro-movement, or shield degradation. When that happens, the failure pattern is usually:
-
faults that occur only at specific robot positions
-
intermittent feedback/control alarms that disappear after restart
-
sporadic stops during high-acceleration moves
-
increased noise sensitivity when nearby equipment switches (welders, VFDs, contactors)
Replacing with the correct ABB-specified part number is a standard way to remove uncertainty—especially in cells where diagnosing intermittent noise issues costs more than the cable.
Installation and Replacement Checklist
| Step | What to do | Why it helps |
|---|---|---|
| Verify exact part number | Confirm 3HAC2493-1 on label and documentation | Avoid near-miss substitutions that “almost fit” |
| Confirm length and routing | Ensure 7 m routing matches existing clamps and travel loops | Prevent over-tension, snagging, and early fatigue |
| Maintain separation from power cables | Route signal lines away from motor/power bundles where feasible | Reduces EMI coupling into sensitive signals |
| Respect bend radius | Keep bends gradual, especially near connectors | Reduces conductor and shield fatigue |
| Post-install motion test | Run full-range moves slowly, then under normal cycle profile | Catches tension points before production restarts |
Notes for Procurement and Cross-Reference
If your internal BOM references older ABB numbers, ABB’s product detail sheet lists replaced product IDs: 3HAB2682-1 and 3HAB2678-1.
That is helpful when you’re matching legacy service documentation or older spare-part lists.
Also, be cautious with random web catalog pages that assign unrelated product identities to the same number; for example, some reseller content incorrectly describes 3HAC2493-1 as a FlexPendant/teach pendant, which conflicts with ABB’s catalog description of a 7 m signal cable. The ABB catalog description and the ABB-style product detail sheet are the more reliable anchors for identification.
Product Positioning Summary
ABB 3HAC2493-1 is best understood as an OEM-defined 7 m signal/control cable used within ABB Robotics harnessing and controller ecosystems—particularly where stable signal transmission is critical for robot motion units, external axes/positioners, and compact controller harnessing.
For maintenance and spares planning, its value is not “a cable you can replace with anything,” but a standardized part that helps keep your cell predictable under industrial noise and continuous-duty cycling.
