The HID-5395-CK100 is a compact, wall-mounted proximity card reader engineered for access control applications requiring both aesthetic integration and reliable credential recognition. Built on 125 kHz proximity technology, this reader delivers consistent performance across corporate, industrial, healthcare, and secure facility environments. The potted, weatherproof enclosure is sized to match standard U.S. switch plates and supports both indoor and outdoor deployment, making it a versatile choice for perimeter checkpoints, facility entrances, and interior access control zones.
The HID-5395-CK100 delivers consistent credential recognition across the HID proximity ecosystem. Typical maximum read ranges vary by credential type and local installation conditions: ProxCard II cards up to 5.5 inches (14 cm), ISOProx II, DuoProx II, and Smart ISO/DuoProx cards up to 5 inches (12.7 cm), Proximity & MIFARE hybrid cards up to 5 inches (12.7 cm), ProxCard Plus cards up to 1.5 inches (3.8 cm), ProxKey II keyfobs up to 2 inches (5.1 cm), and Microprox tags up to 3 inches (7.6 cm). Environmental and mounting conditions may affect actual operating range in the field.
The HID-5395-CK100 integrates seamlessly into both legacy and contemporary access control systems. Wiegand interface supports cable runs up to 500 feet (150 m), enabling flexible controller placement and reducing installation complexity in large facilities. Clock-and-Data interface supports up to 50 feet (15.2 m) of cable distance, suitable for standard office and facility deployments. DC power input (5–16 VDC) connects directly to linear power supplies, eliminating battery maintenance and supporting continuous, uninterrupted operation. The reader requires 5–16 VDC from the access control panel or dedicated power supply, with peak current demand of approximately 115 mA at lower voltages.
Engineered for reliability in demanding environments, the ThinLine II operates across a full temperature range of -22°F to 150°F (-30°C to 65°C) and withstands humidity up to 95% relative humidity (non-condensing). The two-piece, potted enclosure design protects internal circuitry from moisture and environmental contaminants, supporting both controlled indoor spaces and outdoor gatehouse, perimeter, and entrance applications. The reader weighs 3.3 oz. (94 grams) and integrates directly into door frames, wall plates, and surface-mount installations with minimal structural modification.

The HID HID-5395-CK100 is a reliable proximity reader that fits naturally into both new deployments and retrofit projects. During system planning, the dual-interface capability is a genuine advantage—you're not locked into a single protocol, and the 500-foot Wiegand distance spec gives you real flexibility in large facilities where controller placement matters. The weatherproof potted design is substantive, not just marketing; it actually performs outdoors without the fragility you see in some competitive readers.

Deployment Considerations:
For integrators managing mixed-credential environments or upgrading from older HID proximity systems, the ThinLine II delivers the compatibility and environmental durability you need without overcomplicating installation. It's a straightforward, field-proven choice for facilities that require both aesthetics and uninterrupted access control performance.
