Product Overview
The DO-KR200EM and DO-KR200MF card access systems are engineered for office access control, providing reliable identification for employee entry, visitor management, and restricted area control. System integrators and commercial facility managers choose these readers for their consistent read performance, durable epoxy-potted construction, and straightforward integration with existing Wiegand-based controllers. The DO-KR200EM operates at 125KHz for proximity card reading up to 10 cm, while the DO-KR200MF supports 13.56MHz Mifare cards with a read range up to 5 cm, making both models suitable for offices that require dependable, low-maintenance access control across multiple entry points.
Product Advantages
Office environments demand access control hardware that operates reliably under continuous use, withstands indoor and outdoor conditions, and integrates without complex configuration. The DO-KR200EM and DO-KR200MF address these requirements through solid epoxy potting that protects internal electronics against moisture and physical impact, an IP65 waterproof rating that enables installation on exterior doors and loading bays, and reverse polarity protection that prevents damage during installation. For B2B buyers such as security distributors, system integrators, and facility management contractors, these readers reduce on-site service calls and warranty claims because the sealed construction minimizes failure from humidity, dust, or temperature variation. The 26 or 34-bit Wiegand output format ensures direct compatibility with most commercial access control panels, allowing bulk deployment across office buildings without controller upgrades.
Key Features
- 125KHz Proximity or 13.56MHz Mifare Reading – The DO-KR200EM reads 125KHz proximity cards up to 10 cm; the DO-KR200MF reads 13.56MHz Mifare cards up to 5 cm. Both support common credential formats used in office access systems.
- Wiegand Output Format – 26 or 34-bit Wiegand (default) enables direct connection to standard access control panels from multiple manufacturers, simplifying system integration for project contractors.
- Easy Installation on Metal Surfaces – Designed for mounting on metal door frames or mullions without read range degradation, which is essential for office doors with metal construction.
- External LED and Buzzer Control – Two input ports allow external control of LED indicators and buzzer, giving system integrators flexibility to customize visual and audible feedback based on office access rules.
- Indoor and Outdoor Operation – The IP65-rated, epoxy-potted housing supports installation in covered outdoor areas, parking lot entrances, and building perimeter doors.
- Reverse Polarity Protection – Prevents damage from incorrect wiring during installation, reducing on-site troubleshooting and replacement costs for wholesale buyers managing large deployments.
- Solid Epoxy Potted Construction – Encapsulated electronics resist vibration, moisture, and temperature cycling, extending service life in commercial environments with high traffic.

Industrial Applications
System integrators and commercial security contractors deploy the DO-KR200EM and DO-KR200MF across multiple office environments where credential-based access control is required. Typical use cases include employee entrances in corporate office buildings, lobby turnstile integration, internal door access for server rooms or management floors, parking garage pedestrian gates, and back-of-house staff entrances in mixed-use commercial facilities. The 125KHz model supports legacy proximity card systems still common in existing office buildings, while the 13.56MHz model meets modern security requirements for Mifare-based credentials used in multi-tenant offices and co-working spaces. For distributors and project managers sourcing for multiple client sites, both models share the same form factor and mounting dimensions, simplifying inventory management and installation training across different projects.
OEM / ODM Manufacturing Support
As a manufacturer of RFID readers and access control components, do rfid reader manufacturer offers OEM and ODM services for the DO-KR200EM and DO-KR200MF product lines. Customers purchasing for wholesale distribution or large-scale project deployment can request customized branding, packaging, and labelling to match their portfolio. The factory supports modifications to LED colour sequences, bezel colour options, and cable length specifications depending on minimum order quantities. For system integrators who require a consistent appearance across all hardware installed at a client site, OEM customization eliminates visible brand mismatch between readers and other access control components. Bulk procurement with custom branding also strengthens distributor brand recognition in local markets.
Factory Production Advantages
The production facility behind the DO-KR200EM and DO-KR200MF maintains stable manufacturing capacity for both standard and custom orders. Each reader undergoes functional testing for read range, Wiegand output integrity, and current draw before shipment. The epoxy potting process is performed under controlled conditions to ensure consistent sealing across all units, which is critical for batches destined for outdoor or high-humidity installations. With experience producing RFID readers for commercial security applications, the factory manages raw material sourcing for ABS+PC enclosures, PCB components, and cable assemblies to maintain consistent lead times for wholesale buyers. Production records are retained for batch traceability, supporting after-sales technical support and warranty handling for long-term distributor合作关系.
Bulk Supply & Project Deployment Support
Distributors and system integrators ordering the DO-KR200EM or DO-KR200MF for multi-site office deployments benefit from bulk pricing, coordinated delivery scheduling, and technical documentation support. The factory can consolidate orders for mixed models into single shipments to reduce freight costs for wholesale customers. For project contractors managing installation across multiple office floors or buildings, consistent batch consistency in read range and housing finish prevents on-site compatibility issues. The default 26/34-bit Wiegand output ensures that all readers in a deployment communicate identically with the head-end controller, reducing programming time during commissioning. Technical support is available for integration questions related to wiring, LED control, and Wiegand data format, helping project teams resolve configuration issues during the deployment phase.
