Paxton Net2 & Switch2 Tokens Explained (Password-Protected 125 kHz)

Paxton Net2、Switch2 和英國市場

Paxton Access is the dominant access-control manufacturer across the UK and Ireland, with Net2 and Switch2 representing its two principal product lines. Net2 is a networked, software-managed platform suited to multi-door commercial and enterprise sites; Switch2 is the standalone, simpler sibling for single-door or small-site deployments. Both platforms use the same token form factor and, critically, the same password-protected 125 kHz credential technology, which means the credential supply question is identical across both product families.

Paxton龐大的安裝基礎——從全科醫生診所到多層停車場的數萬個場所——使得相容令牌的供應具有重要的商業意義。OEM鑰匙扣價格昂貴，當一個場所需要發放五十或一百個感應媒介時，成本會迅速累積，採購團隊通常會尋找合格的獨立供應商。這種需求完全符合我們的產品範圍，涵蓋在我們的 適用於所有主要格式的相容鑰匙扣計劃.

Paxton的令牌系列涵蓋多個零件編號——最常訂購的是標準黑色鑰匙扣（零件號695-644）和近距離感應卡等效產品——但底層感應媒介格式在標準令牌系列中是一致的。一旦您了解該格式在內部實際需要什麼，按零件編號參考訂購相容庫存就非常簡單。

對於負責多個Paxton場所的安裝人員和設施經理來說，相容供應的經濟效益是顯而易見的。即使是微薄的單價節省，在一個經常涉及員工流動、鑰匙扣丟失和新員工發放的計劃中，也會累積成可觀的數額。來自專業感應媒介製造商的獨立供應，以更具競爭力的價格提供與OEM庫存相同的註冊體驗，並額外受益於專注於感應媒介品質和相容性保證的供應商。

Why a Password-Protected Transponder Is Not a Plain 125 kHz Proximity Card

Standard 125 kHz read-only credentials — EM4100, HID Prox, Indala — broadcast a fixed ID on request with no authentication layer. Any compatible reader that knows the encoding simply reads and acts on that ID. A password-protected transponder operates differently: it is a bidirectional, password-authenticated LF protocol. Before the tag transmits its identifier, the reader and the tag perform a mutual authentication exchange using a shared secret embedded in the chip's protected memory pages.

The practical consequence is that a compatible crypto fob must be correctly configured — password and memory layout set to match what the Paxton controller expects — before it will be enrolled or recognised. A blank crypto transponder chip that has not been configured will simply not respond correctly to a Net2 or Switch2 reader. This is the source of frequent confusion: buyers familiar with plain prox cards assume any 125 kHz blank will substitute in, only to find the controller silently rejects credentials that haven't been prepared for the format. Our T5577解釋指南 covers the broader landscape of programmable LF blanks, but the password-protected transponder is its own distinct protocol class that T5577 does not cover.

The password-protected architecture also means this credential class sits in a different compliance category to plain prox. Sites using it get a meaningful step up in LF-layer security compared to EM4100 or standard 26-bit Wiegand cards. It is not a high-security smart-card protocol — that tier belongs to AES-encrypted HF formats — but it is substantially more robust than unprotected prox, which matters for the risk profile of the many medium-security commercial sites Paxton serves.

Understanding this distinction is also important for procurement conversations. When a facilities manager asks whether a compatible fob will 'work the same way,' the answer is yes — but only because the compatible fob has been correctly prepared at the protocol level, not simply because it shares the 125 kHz operating frequency with plain prox credentials. The preparation step is what makes our compatible crypto fob a direct functional equivalent to the Paxton OEM token.

令牌零件編號及其含義

Paxton發布了一個簡單的零件編號分類。標準的Net2鑰匙扣是695-644（黑色表面，ISO標準鑰匙圈環）。還有卡片形式的感應媒介（695-651及相關產品）和用於Net2讀卡器系列的近距離感應卡。Switch2令牌共享相同的感應媒介格式，標準鑰匙扣零件編號交叉適用——平台區別在於控制器硬體，而不是令牌本身。

When procuring compatible stock, the part number gives you the physical form factor you need, but the format specification that matters for compatibility is the password-protected transponder configuration, not the moulded case reference. Our Paxton Net2/Switch2相容鑰匙扣 產品列表直接對應標準的695-644等效產品：相同的尺寸、相同的環位置、相同的晶片類別，並編程為正確的出廠配置。買家可以在採購訂單中參考OEM零件編號以進行追溯；我們將按照該規範履行訂單。

如果您不確定您的場所是使用標準令牌格式還是Paxton較不常見的近距離感應卡變體之一，我們的 門禁卡格式識別指南 將詳細介紹物理檢查步驟，並在相關情況下，介紹確認正在使用的協議的讀卡器輸出檢查。

Sites that have accumulated a mix of credential generations — perhaps older Switch2 tokens alongside newer Net2 installations — will find that compatible supply simplifies reordering considerably. Rather than tracking OEM stock levels across multiple part-number variants, a single compatible fob specification covers the standard password-protected 125 kHz credential type used across the Paxton estate. The physical form factor of the 695-644 equivalent is the most commonly held, and our standard stock reflects that.

生產相容的Paxton令牌

正確生產的 相容Paxton鑰匙扣 starts with a genuine password-protected 125 kHz blank — not a generic LF blank, and not an EM4100 credential relabelled. The chip's authentication block and configuration pages must be written to the correct state before the fob is packaged. This is a programming step, not a duplication exercise: the output is a blank credential in the right protocol state, ready for your Net2 or Switch2 system to enrol with its own site-specific settings, just as it would enrol a factory-fresh OEM token.

Enrolment happens through the Paxton software in exactly the same way as with OEM stock. The controller assigns a token ID, sets permissions and time profiles, and writes that enrolment to its database. The compatible fob holds no site-specific data before enrolment — it simply presents itself to the reader as a valid password-protected 125 kHz credential in the expected configuration, at which point the Paxton system takes over. This is the standard model for 企業專有相容感應媒介 在所有主要製造商中的標準模型。

此階段的品質控制很重要。未寫入正確配置的晶片將在註冊時被默默拒絕，這會浪費現場時間。我們的生產過程包括對每個鑰匙扣批次進行回讀驗證步驟。為大型場所訂購的買家應在全面交付之前要求少量樣品進行台架測試——這是任何關鍵門禁耗材的標準做法。

回讀驗證步驟值得特別提及。批次中的每個鑰匙扣都根據參考配置文件進行檢查，以確認身份驗證區塊和記憶體頁面處於Paxton Net2和Switch2註冊的正確狀態。這消除了不相容性默默到達客戶現場的風險。如果您的部署涉及現場規模的推廣——例如，為一個新建項目提供一百個鑰匙扣——在全面發放之前確認生產批次品質是專業的方法，我們積極支持為此目的的樣品請求。

比較Paxton令牌與普通125 kHz近距離感應卡

The table below sets out the key differences between Paxton Net2/Switch2 password-protected tokens and the plain-prox credentials used in basic 125 kHz systems. The distinction is relevant both for sourcing decisions and for understanding what compatible supply actually involves.

目前操作普通近距離感應卡並考慮遷移到Paxton——或評估Paxton的感應媒介層級是否符合其安全要求——的場所會發現此比較很有用。該 相容與原廠門禁卡採購指南 涵蓋了更廣泛的採購問題，包括何時相容供應是簡單的，以及何時需要更多謹慎。

批量訂購相容Paxton鑰匙扣

相容Paxton令牌可透過我們的 125 kHz LF近距離感應系列 提供單件、十件裝和站點規模的數量。標準庫存涵蓋與 695-644 等效的鑰匙扣形式；卡片形式的 Paxton 相容感應媒介可應要求提供。標準庫存的交貨時間很短；較大的客製化批次應提前適當通知訂購。

A useful alternative for multi-site operators or access-control installers managing several Paxton estates is our crypto transponder blank fob — the unprogrammed password-protected 125 kHz token that some system integrators prefer to encode in-house using their own Paxton-connected tooling. For direct issuance without additional programming steps, the pre-configured Paxton Net2/Switch2相容鑰匙扣 是正確的產品。如果您除了 Paxton 站點外還管理 PAC 或 Stanley 安裝，我們的 PAC 相容令牌鑰匙扣 在相同的訂購流程下涵蓋該格式。

對於投標新 Paxton 安裝或接管現有站點管理的安裝人員來說，從一開始就建立可靠的相容鑰匙扣供應鏈可以減少對單一供應商渠道的依賴，並在感應媒介生命週期中提供價格穩定性。我們定期與管理多個站點的門禁安裝人員合作，並可應要求支援總括訂單、分階段交付和格式驗證。
