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

Paxton Net2、Switch2 和英国市场

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 庞大的安装基础——从全科医生诊所到多层停车场，数万个站点——使得兼容令牌供应具有重要的商业意义。OEM 钥匙扣带有溢价，当一个站点需要发行五十或一百个门禁卡时，溢价会迅速累积，采购团队通常会寻找合格的独立供应商。这种需求完全符合我们的产品范围，涵盖在我们的 适用于所有主要格式的兼容钥匙扣计划.

Paxton 的令牌系列涵盖多个零件号——最常订购的是标准黑色钥匙扣（零件 695-644）和感应卡等效产品——但底层门禁卡格式在标准令牌系列中保持一致。一旦您了解格式实际需要什么，通过零件号参考订购兼容库存就变得简单。

对于负责多个 Paxton 站点的安装人员和设施经理来说，兼容供应的经济效益是显而易见的。即使是适度的单位成本节省，在一个经常涉及员工流动、钥匙扣丢失和新员工发放的计划中，也会大幅累积。专业门禁卡制造商的独立供应以更具竞争力的价格提供与 OEM 库存相同的注册体验，并额外受益于专注于门禁卡质量和兼容性保证的供应商。

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 解释指南 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.

令牌零件号及其含义

Paxton发布了直接明了的部件号分类法。标准的Net2钥匙扣是695-644（黑色饰面，ISO标准钥匙环）。还有卡式门禁卡（695-651及相关产品）和用于Net2读卡器系列的感应卡。Switch2令牌共享相同的门禁卡格式，标准钥匙扣部件号可交叉应用——平台区别在于控制器硬件，而非令牌本身。

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兼容钥匙扣 产品列表直接对应标准695-644等效产品：相同的尺寸，相同的环形位置，相同的芯片类别，并已编程为正确的出厂配置。买家可以在采购订单中注明OEM部件号以进行追溯；我们将按该规格履行订单。

如果您不确定您的站点是使用标准令牌格式还是Paxton的较不常见的感应卡变体之一，我们的 门禁卡格式识别指南 将详细介绍物理检查步骤，并在相关情况下，通过读卡器输出检查确认正在使用的协议。

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.

生产兼容的Paxton令牌

正确生产的 兼容Paxton钥匙扣 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 企业专有兼容门禁介质 在所有主要制造商中的标准模式。

此阶段的质量控制至关重要。未写入正确配置的芯片将在注册时被静默拒绝，这会浪费现场时间。我们的生产过程包括对每个钥匙扣批次进行回读验证步骤。为大型站点订购的买家应在全面交付前要求提供样品进行台架测试——这是任何关键门禁耗材的标准做法。

回读验证步骤值得特别提及。批次中的每个钥匙扣都对照参考配置文件进行检查，以确认认证块和内存页面处于Paxton Net2和Switch2注册的正确状态。这消除了不兼容性悄然到达客户站点的风险。如果您的部署涉及站点规模的推广——例如，为新建筑提供一百个钥匙扣——在全面发行前确认生产批次质量是专业的方法，我们积极支持为此目的的样品请求。

Paxton令牌与普通125 kHz感应卡的比较

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.

目前运营普通感应卡并考虑迁移到Paxton的站点——或评估Paxton的门禁介质层级是否符合其安全要求的站点——会发现此比较很有用。 兼容卡与原装门禁卡采购指南 涵盖了更广泛的采购问题，包括何时兼容供应是直接的，何时需要更多谨慎。

批量订购兼容Paxton钥匙扣

兼容Paxton令牌可通过我们的 125 kHz LF感应范围 以单件、十件装和站点规模数量提供。标准库存涵盖与695-644等效的钥匙扣外形；卡式Paxton兼容门禁卡可应要求提供。标准库存的交货时间短；较大的定制批次应提前适当通知订购。

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兼容钥匙扣 是正确的产品。如果您除了Paxton系统外还管理PAC或Stanley安装，我们的 PAC 兼容令牌钥匙扣 涵盖了相同订购流程下的该格式。

对于竞标新Paxton安装或接管现有系统管理的安装商而言，从一开始就建立可靠的兼容钥匙扣供应链可减少对单一供应商渠道的依赖，并在门禁介质生命周期内提供价格稳定性。我们定期与管理多个站点系统的门禁安装商合作，并可应要求支持总括订单、分阶段交付和格式验证。
