h1>Product Overview
Office access control requires reliable identification technology that integrates seamlessly with existing security infrastructure. The DO-KR200E and DO-KR200M card readers from DO RFID Reader deliver field-proven performance for commercial door access deployments. The DO-KR200E operates at 125KHz for proximity card reading, while the DO-KR200M supports 13.56MHz Mifare technology, giving system integrators and facility managers flexibility when specifying reader hardware for multi-tenant office buildings, corporate campuses, and restricted work zones.
These compact readers mount directly onto metal door frames or mullions, making them suitable for both retrofit upgrades and new construction projects. With Wiegand output (26 or 34 bit), the readers interface with most major access control panels, reducing integration effort for security contractors and commercial installers. The epoxy-potted enclosure and IP65 rating allow reliable operation in indoor and outdoor environments, including covered entrances, parking gates, and perimeter access points.
Procurement teams, distributors, and project managers choose this reader series for its consistent performance, straightforward installation, and compatibility with existing Wiegand-based access systems. The stable production capacity at the DO RFID Reader factory ensures steady supply for large-scale deployments and multi-site rollouts.
Product Advantages

Industrial Applications
System integrators, security contractors, and facility management teams deploy the DO-KR200E and DO-KR200M card readers across a range of commercial and institutional environments. Typical applications include office building entrance doors, internal access zones, server rooms, parking lot pedestrian gates, co-working space entry points, and staff-only areas in healthcare or education facilities.
The Wiegand output compatibility means these readers integrate with popular access control panels from multiple manufacturers, reducing the need for custom software development or middleware during project deployment. For wholesalers and distributors serving the commercial security market, stocking a single reader series that supports both 125KHz and 13.56MHz credentials simplifies inventory management and reduces the need for multiple SKUs.
Industrial buyers and procurement managers responsible for multi-site access rollouts benefit from the reader’s consistent read performance, straightforward mounting process, and reliable operation across temperature extremes. The epoxy potting and IP65 rating also reduce failure rates in environments exposed to dust, moisture, or temperature fluctuations, lowering total cost of ownership over the system lifecycle.
OEM / ODM Manufacturing Support
DO RFID Reader offers OEM and ODM customization for the DO-KR200 reader series to meet specific project or branding requirements. Custom housing colours, logo printing or laser engraving, packaging design, and firmware parameter adjustments (such as Wiegand format or LED behaviour) can be configured for volume orders. Project teams working on large-scale access control deployments often require consistent batch appearance and identical electrical characteristics across thousands of units. The DO RFID Reader factory implements production batch tracking and routine parameter verification to maintain repeatability across manufacturing runs.
For ODM customers who integrate the reader into a complete access control solution, the factory can adapt connector types, cable lengths, or mounting brackets to match existing installation workflows. Custom documentation and labelling are also available for private-label distribution channels. Procurement teams should contact DO RFID Reader with specific technical requirements and estimated annual volumes to discuss customization feasibility and lead times.
Factory Production Advantages
The DO RFID Reader factory has accumulated production experience in RFID reader manufacturing, supporting steady supply for both domestic and export orders. Production lines are configured for efficient assembly of epoxy-potted readers, with in-process quality checks covering read range consistency, current consumption, Wiegand signal integrity, and visual inspection of housing finish. This structured production approach helps maintain batch-to-batch uniformity, which is critical for system integrators and distributors who supply readers across multiple projects simultaneously.
Raw material sourcing for ABS+PC enclosures, electronic components, and potting compound follows established supplier qualification procedures. The factory maintains inventory of commonly used components to reduce lead time fluctuations during peak order periods. For wholesale buyers and long-term distribution partners, production capacity can be allocated in advance based on rolling forecasts, enabling more predictable delivery scheduling. Export shipments are packed according to commercial transport standards, with individual unit protection and consolidated carton packaging for bulk orders.
Bulk Supply & Project Deployment Support
Wholesale buyers, system integrators, and project contractors benefit from bulk pricing and stable production capacity when sourcing the DO-KR200E and DO-KR200M readers. The factory supports order volumes ranging from hundreds to tens of thousands of units, with production lead times communicated at the time of order confirmation. For large-scale deployment projects where delivery timing directly affects installation milestones, the factory can prioritize production scheduling to meet project deadlines.
Technical documentation, including installation guides, wiring diagrams, and Wiegand output pin assignments, is provided with each shipment to reduce on-site configuration time for installation crews. For distributors who stock these readers for ongoing resale, consistent product specifications across batches eliminate the need for frequent requalification testing. Procurement teams evaluating long-term supply agreements should request pricing for annual volume commitments and discuss buffer stock arrangements with the sales team.
Project managers overseeing multi-building access system upgrades often require coordinated delivery of readers, credentials, and control hardware. The DO RFID Reader factory can coordinate with logistics partners to consolidate shipments or stage deliveries according to project phasing. Contact DO RFID Reader for current lead times, bulk pricing tiers, and export shipping options for your region.
