Side Connector Accessory Port Protection for Next-Generation Handheld Transceivers
Safeguard Sensitive Digital Interface Contacts
Seal your compact multi-pin accessory port against destructive moisture ingress and fine industrial grit.
The genuine Motorola PMHN4429A Side Connector Dust Cover for MOTOTRBO R7 is an authentic original equipment manufacturer (OEM) protective component designed specifically for slim-chassis digital portable transceivers. When external audio accessories like remote speaker microphones or surveillance earpieces are uncoupled, the critical side communication terminal is left entirely exposed to the elements. The Motorola PMHN4429A provides a flush, tight-fitting barrier that isolates the delicate data lanes and gold-plated power contacts from airborne contaminants, maintaining optimal operational conductivity. The Motorola PMHN4429A is the updated version of the Motorola PMHN4429.
Engineered for field technicians, heavy industrial manufacturing teams, public safety officers, and private security forces, this flexible polymer cap addresses a major point of hardware failure. Airborne dust, metallic shavings, rain exposure, and perspiration film can easily settle into unshielded ports, leading to signal degradation, static interference, or corrosion. Deploying the Motorola PMHN4429A preserves the structural and electrical reliability of your handheld fleet, shielding the specialized mini-GCAI terminal format without interfering with the radio's sleek profile or clothing clip attachments.
This factory-authorized accessory is an essential replacement for lost, misplaced, or worn factory-issued terminal shields. Installation is entirely plug-and-play, snapping directly into the lateral connector slot without the need for prying tools or hardware fasteners. Fleet supervisors should verify their specific radio series before purchasing, as this low-profile port protector is optimized exclusively for mini-GCAI dimensions and will not secure properly over older, large-scale multi-pin radio side-car configurations.

Frequently Asked Questions
Is an external screw required to secure this cover to the radio?
No. The Motorola PMHN4429A uses integrated friction-locking tabs engineered to snap directly into the side recess of the radio housing. It holds firmly in place during daily field use without the need for thumbscrews or mechanical fasteners.
Can this cover be used on standard older MOTOTRBO or APX series radios?
No. This dust cover is custom-molded to fit the ultra-compact mini-GCAI connection terminal format. It will not fit properly over older, wider multi-pin accessory blocks found on legacy transceivers.
Does this product package contain a multi-pack or a single unit?
This item is supplied as a single, genuine replacement side-port cover piece. It is ideal for individual field maintenance needs or replacing a single lost factory-issued port protector.
