What Is the M1500A Compatible 3-Lead ECG Trunk Cable?

The IPR Medical ET-3005R-AA-A is a compatible aftermarket (not OEM) 3-lead ECG trunk cable that replaces OEM part M1500A. A trunk cable is the link between the patient leadwires and the monitor; this one is reusable, set up for limb lead placement, AHA-designated, and 8.2 ft (2.5 m) long. It is defib-proof and intended for ECG monitoring. The leadwire type it pairs with is given in the Lead Type row of the Specifications table.

Compatible Monitor Models

The compatibility list for this 3-lead trunk cable is long and covers models from several manufacturers. Among them are select Welch Allyn models such as the Propaq Encore 206EL and 242, select Solaris models such as the NT3C, NT3E, and NT3F, the SurgiVet V9200 listed under Smiths Medical / BCI, and select Nihon Kohden and Newtech models. Every model is listed by manufacturer in the Compatible Monitor Models table on the Specifications tab, and checking your exact model there first is the surest way to order the right cable.

Design and Construction

The ET-3005R-AA-A is configured for a 3-lead limb setup and uses AHA designation. It measures 8.2 ft (2.5 m) and is listed as defib-proof. The cable is reusable; clean it between patients following your facility protocol. Packaging is one cable per bag. Match the lead type shown in the Specifications table to the leadwires already in use on your floor.

When to Replace Your 3-Lead ECG Trunk Cable

Every lead signal travels through the trunk cable, so a fault here tends to affect all three leads at once: flat or intermittent traces on every lead, lead-off alarms that persist with fresh electrodes, or noise that appears whenever the cable is flexed. On inspection, look for a cracked or kinked jacket, a damaged connector housing, and bent pins at the monitor connector. Swapping in a known-good trunk cable while keeping the same leadwires and monitor is a quick way to confirm where the fault lies.

Cross Reference and Interchange Part Numbers

OEM part M1500A is the primary reference for this compatible trunk cable, and OEM numbers 989803103811 and 453561233921 also cross-reference to it. The rest of the OEM and aftermarket interchange numbers are collected, brand by brand, in the Cross Reference / Interchange Part Numbers table on the Specifications tab.
