Honeywell PX-4-H HID Clamshell Proximity Card
Overview
The Honeywell PX-4-H is an HID-format proximity card in a clamshell form factor, designed for commercial access control deployments. The clamshell housing provides a more durable credential than a standard ISO card — the laminated construction resists bending and delamination that can cause read failures in high-use environments like employee entrances, parking garages, and multi-tenant facilities. If your access control readers are HID-compatible, the PX-4-H is a straightforward credential fit without requiring reader replacement or reconfiguration.
Manufactured in the US, the PX-4-H is a genuine Honeywell commercial-grade credential. For integrators managing large deployments, Honeywell also offers related bundle variants — the PX-4-H-SPEC and PX-4-H25 — which may suit specific quantity or formatting requirements depending on your project scope. For broader Honeywell access control products, the PX-4-H fits naturally into existing HID-based credential programs.
Key Features
- Clamshell Form Factor: The rigid clamshell housing is thicker than a standard card, which improves durability in wallet or badge-reel carry — reducing credential failures that require re-issuance and disrupt access operations.
- HID Proximity Technology: Compatible with the broad installed base of HID-format access control readers — no firmware changes or reader swaps required in most commercial deployments.
- Commercial-Grade Construction: Manufactured in the US; factory-new genuine Honeywell credential — not a grey-market or parallel-import product, which matters when you need consistent format and facility code encoding across a card batch.
- Lightweight Carry: At 0.6 lb per pack, the PX-4-H is practical for bulk deployment — integrators issuing credentials across multiple doors or floors won't face logistics issues with shipping or storage.
Integration & Compatibility
The PX-4-H is designed for commercial access control environments using HID proximity readers. It is listed as compatible with commercial systems, making it suitable for corporate offices, warehouses, and multi-door commercial facilities already running HID-based infrastructure. If you are evaluating credential options for a new installation, review your panel and reader specifications against HID proximity format requirements before ordering. Related bundle SKUs (PX-4-H25) may offer quantity packaging better suited to larger rollouts — consult your project BOM before selecting between variants. For guidance on pairing credentials with the right readers and panels, reviewing an access control reader selection guide will help confirm compatibility before procurement.
Frequently Asked Questions
Q: What form factor is the PX-4-H?
A: The PX-4-H uses a clamshell form factor — a rigid, laminated housing that is thicker and more durable than a standard ISO proximity card, reducing bend-related read failures in daily use.
Q: Is the PX-4-H compatible with standard HID proximity readers?
A: Yes. The PX-4-H is an HID-format proximity card and is designed to work with HID-compatible readers in commercial access control systems. Confirm your reader's supported credential format before ordering.
Q: What is the difference between PX-4-H, PX-4-H-SPEC, and PX-4-H25?
A: These are related bundle or variant SKUs within the same product family. The PX-4-H25 likely represents a 25-card quantity pack. Confirm specific packaging and encoding differences with your distributor before selecting the right SKU for your project.
Q: Where is the PX-4-H manufactured?
A: The PX-4-H is manufactured in the United States.
Q: Does the PX-4-H carry a manufacturer warranty?
A: The PX-4-H is covered by a Honeywell manufacturer warranty. Specific duration terms were not available in published documentation — contact Honeywell directly or request warranty documentation at time of purchase.
The PX-4-H is a credential decision that often gets underthought — integrators focus on readers and panels, then order cards last minute without confirming format details. The clamshell construction on the PX-4-H is the spec worth paying attention to: the rigid housing holds up to years of daily badge-reel or wallet carry far better than standard laminated ISO cards, which means fewer re-issuance calls and fewer help-desk interruptions for a credential that stopped reading.
Technical Highlights:
- Clamshell Durability: Rigid housing resists the flex-and-delaminate failure mode common in thin ISO cards — worth specifying in high-use environments like manufacturing floors or shift-change chokepoints.
- HID Proximity Format: Directly compatible with the dominant installed base of commercial HID readers — no reader firmware changes or infrastructure investment required in most existing deployments.
- US-Made Credential: Country of origin is the US, which matters for procurement compliance in certain government or regulated commercial facilities.
Deployment Considerations:
- Before placing a bulk order, confirm the facility code and card number encoding format required by your access control panel — credential encoding is not interchangeable across all HID reader configurations, and re-encoding or returning a large card batch is costly.
- The PX-4-H25 variant exists within the same family and likely ships in 25-card quantity packs — for large rollouts, evaluate whether the per-card cost or packaging of that SKU better fits your project BOM.
The PX-4-H is the right specification for commercial facilities with existing HID proximity infrastructure where credential durability and consistent US-sourced supply are priorities — particularly relevant in corporate campus environments managing hundreds of active cardholders with regular turnover.
