UL AWM 1571 PVC Signal Wire 24 AWG — Class 2 Internal Wiring for Data and Signal Circuits, 30 Vac, 80°C
UL AWM 1571 in 24 AWG with extruded PVC insulation is a single-conductor signal wire rated 80°C maximum at 30 Vac, recognised for internal wiring of Class 2 circuits in electronic equipment. The 24 AWG size is a widely adopted standard for internal data and signal conductors — its balance of conductor cross-section, bend flexibility and insulation diameter makes it a natural fit for board-to-sensor signal runs, data acquisition wiring and Class 2 control signal conductors inside compact and mid-size electronic equipment. CableApex supplies UL AWM 1571 24 AWG as a UL Recognized Component — file on record.

Why 24 AWG Is the Standard Signal Wire Gauge
| Property | Finer (30–28 AWG) | 24 AWG (this page) | Heavier (22 AWG) |
|---|---|---|---|
| DC resistance | Higher — limits longer runs | Moderate — suits most signal runs | Lower — suited for longer circuits |
| Bundle diameter | Very slim | Slim — fits dense harnesses | Slightly wider |
| Termination ease | Requires care | Easy — widely tooled | Easy |
| Flexibility | High | Good | Moderate |

Applications
Within its permitted use — internal wiring of Class 2 circuits in electronic equipment — UL AWM 1571 24 AWG PVC suits board-to-sensor signal conductors, data acquisition wiring harnesses, low-voltage Class 2 control signal runs and internal interface wiring between modules inside electronic equipment operating within 30 Vac. The 24 AWG cross-section is compatible with the widest range of standard crimp and IDC termination tooling, which simplifies harness assembly in production environments. For applications outside Class 2 internal electronic wiring, confirm application suitability before specifying.
