Tool-Free Audio Accessory Retainer Clip Kit for MOTOTRBO R2 (25-Pack)
Genuine Motorola Solutions Original 25-pack audio connector retainer clips designed to prevent jack wear and strain on MOTOTRBO R2 portables.
The Motorola PMLN8502A (also cataloged as PMLN8502) is an authentic original equipment manufacturer (OEM) bulk pack of 25 audio accessory retainer clips engineered specifically for the Motorola MOTOTRBO R2 portable two-way radio. Designed for manufacturing plants, security operations, educational campuses, construction sites, and equipment rental depots, this maintenance hardware secures external earpiece and speaker microphone plugs to the radio chassis. Sourced directly from our verified inventory of Motorola Two-Way Radios & Accessories, the PMLN8502A protects your R2 fleet against premature audio port wear, broken pins, and intermittent voice connections.
Repeated plugging and unplugging of audio accessories, combined with cable snagging on jobsite machinery, places heavy mechanical stress on a radio's side connector. The Motorola PMLN8502A provides an essential structural barrier that braces connected accessory plugs flush against the radio body, absorbing lateral tension and preventing accidental disconnections in active work zones compliant with OSHA Standards. Engineered to withstand heavy vibration and snag shock tested under DoD Standards (MIL-STD-810H), each retainer clip snaps on effortlessly by hand without requiring screwdrivers or specialized bench tools. By ensuring that accessory plugs remain securely seated against the side port gaskets, these clips help preserve the radio's factory dust and water resistance certified under IEC Standards (IEC 60529 IP55).

Frequently Asked Questions
What is the difference between part numbers ending in "A", "B", or having no letter?
There is no functional, mechanical, or operational difference. Motorola Solutions uses trailing letter suffixes (such as A, B, or C) to designate internal manufacturing revisions and production lots. A part number cataloged as PMLN8502, PMLN8502A, or a subsequent revision shares identical dimensions, polymer materials, and compatibility.
What is the primary function of the Motorola PMLN8502A retainer clip?
The PMLN8502A snaps onto the MOTOTRBO R2 side accessory connector to lock external audio plugs (such as earpieces and remote microphones) securely in place. It absorbs physical cable pull and strain, preventing damage to the radio’s internal audio jack contacts.
Do I need any tools to install or remove these clips?
No. The retainer clips are engineered for completely tool-free installation. They snap securely into the radio housing recesses by hand and release easily when intentionally unlatched for accessory swaps.
Why is this kit sold in a 25-pack?
Small retention clips and side port dust covers are common wear items that can be misplaced in high-turnover commercial, industrial, and rental environments. The 25-pack allows service managers and depot technicians to maintain ready inventory for fleet maintenance.
Does this retainer clip fit the Motorola CP200d?
No. While the MOTOTRBO R2 uses a 2-pin audio interface similar to the legacy CP200d, the exterior chassis contours and snap-retention grooves are unique to the R2 platform. The PMLN8502A is designed exclusively for the MOTOTRBO R2 housing.
