HID 40NKS-00-000000 SIGNO 40 Pigtail Proximity Reader
Overview
The HID 40NKS-00-000000 is a wall-mounted proximity card reader engineered for straightforward access control integration in commercial and light industrial environments. It communicates via 32-bit Wiegand output (MSB format), which means it translates standard EM proximity cards directly into controller-compatible data frames—no intermediate conversion hardware needed. The reader includes visual and audible feedback: red LED for status, green flash for valid read, and an integrated buzzer. Surface-mount design allows retrofit into existing frame openings without structural modifications.
Key Features
- 32-Bit Wiegand MSB Protocol: Outputs credential data in the standard most access control systems expect, reducing integration friction across legacy and modern panels. Broad compatibility with EM-encoded cards in your existing library.
- Surface-Mount Capability: Installs flush to any flat surface without requiring recessed backing or specialized brackets—cuts installation time on retrofit projects where wall preparation is minimal.
- Integrated Feedback (LED + Buzzer): Green flash + tone confirm a valid read; red LED signals status. Audible confirmation is critical in high-traffic entrances where visual-only feedback misses distracted users.
- Standard Card Profile Operation: Works with conventional proximity cards at typical read distances (typically 3–6 inches for EM cards, depending on card quality and reader tuning). No velocity or IPM (in-process mode) overhead—straightforward read-or-don't-read behavior.
- Wired Connectivity: Connects directly to your access control panel via Wiegand terminals (Data0, Data1, common ground). No network stack, no PoE, no wireless—pure hardwired simplicity.
- Multi-Door Deployment Ready: Each reader on its own Wiegand pair can serve single or multi-reader installations scaled to your panel's input capacity. Parallel configuration typical in warehouse and retail scenarios.
Integration & Compatibility
The 40NKS-00-000000 pairs with any access control panel that accepts Wiegand 32-bit input. This includes legacy 4-wire and 6-wire panels, modern IP-based controllers with Wiegand relay modules, and standalone magnetic locks with simple Wiegand readers. EM 32-bit card encoding is the dominant format globally—your existing card stock almost certainly works without reissuance.
Configuration is site-dependent: some installers bridge multiple readers into a single panel channel; others dedicate a channel per door. Consult your panel's Wiegand input specifications to verify termination and debounce timing. Access control integration guides cover typical wiring scenarios.
When to Choose a Different Model
If your deployment requires mobile credential support (smartphone NFC), biometric fusion, or IP network integration, look to HID's networked reader line—those add IP connectivity and encryption layers unsuitable for this direct Wiegand architecture. If you need high-security FIPS 201 (PIV) compliance, HID offers certified smart-card and PKI readers; this model is EM-only. For outdoor harsh-environment exposure, verify IP rating against your site—standard proximity readers may not handle heavy wash-down or salt spray without additional housing.
Frequently Asked Questions
Q: Does the HID 40NKS-00-000000 work with my existing EM card library?
A: Yes. The 40NKS-00-000000 is designed for standard EM 32-bit proximity cards. It will read any ISO/IEC 11784/11785 or HID ProxCard EM format card in your current inventory without reissuance or re-encoding.
Q: What is the typical read distance for the SIGNO 40?
A: Standard proximity cards typically read 3–6 inches away, depending on card quality, shielding, and environmental RF noise. Exact distance varies by installation—test during commissioning.
Q: Can I mount the 40NKS-00-000000 outdoors?
A: The SIGNO 40 is designed for general commercial and light industrial indoor/covered entry environments. Verify IP rating and temperature range in the datasheet before outdoor deployment; extended UV or salt-spray exposure may require additional housing.
Q: Does the reader support velocity checking or anti-passback?
A: No. The 40NKS-00-000000 delivers raw 32-bit Wiegand frames; anti-passback and velocity logic are handled entirely by your access control panel. This keeps the reader simple and the panel in control.
Q: How many readers can I connect to a single access control panel?
A: Depends on your panel's Wiegand input capacity. Most panels support 1–4 readers per channel. Consult your panel documentation for pinout and supported reader count.

The HID 40NKS-00-000000 (often searched as 40NKS 00 000000) is a no-nonsense proximity reader for integrators working with legacy and modern access control panels that still demand Wiegand. At its core, it translates EM card swipes into standardized 32-bit data frames—a pattern your panel has expected for decades. This simplicity is both strength and constraint: you get bulletproof compatibility with existing control logic, but you forfeit any on-reader intelligence.
Technical Highlights:
- 32-Bit MSB Wiegand Output: Delivers card data in the byte order most legacy panels expect. No endian surprises, no protocol translation layers. Integrates cleanly with 4-wire, 6-wire, and modern relay-backed Wiegand inputs.
- Integrated Audible Feedback (Buzzer + LED): Green flash + tone on valid read eliminates the fumbling users commit when visual-only feedback goes unseen. Red LED status is quick diagnostic during commissioning—immediate feedback on reader power and health.
- Surface-Mount Design: Zero recessed backing required. Flush installation into standard electrical box or trim ring cuts your on-site labor. Matters more than it sounds on retrofit projects where structural modification is forbidden.
Deployment Considerations:
- Read Distance Variability: Standard EM cards read 3–6 inches; degraded cards and RF noise can reduce this. Test your card stock and site RF environment during commissioning. Don't assume uniform performance across all cards in circulation.
- Panel Logic Required: This reader has no anti-passback, no velocity checking, no local decision-making. Your panel owns that intelligence. If your panel lacks robust Wiegand debouncing or multi-reader management, you'll fight timing and false-read issues.
- No Network Path: Pure Wired Wiegand means zero remote monitoring, zero audit log streaming, zero centralized analytics. Suitable for standalone or small multi-reader sites; unsuitable for enterprise deployments demanding real-time alerts across dozens of entry points.
The 40NKS-00-000000 shines in warehouse, retail, and industrial facilities where you already run a solid legacy panel and card refresh is not imminent. Retrofit a reader or two, tie them into existing Wiegand inputs, and you're done. Don't reach for this if you need mobile credentials, networked reporting, or biometric fusion—those demands send you to HID's IP reader line instead.
