Hytronik HC403VRC-KD Detached-type Tri-Level Microwave Occupancy Detector with 1-10V Dimming Output

The Hytronik HC403VRC-KD is a detached-type, high-frequency (microwave) occupancy detector designed for tri-level dimming control via a 1-10V output. Operating at 5.8GHz, the sensor is optimized for building into indoor fixtures such as office lighting, classrooms, and warehouses. It is supplied with a SAM-6 antenna.

Key Specifications & Performance

• Operating Voltage: 120–277VAC, 50/60Hz.
• Load Ratings: Supports capacitive loads up to 400VA at 120V, 800VA at 230V, and 1000VA at 277V.
• Zero-Crossing Detection: Features a software-driven zero-cross relay circuit to minimize in-rush current and extend relay life.
• Efficiency: Standby power consumption is less than 0.5W.

SAM6 High-Bay Sensor Integration

When paired with the SAM6 antenna, the system is specifically configured for high-bay applications:

• Detection Range: Provides a maximum detection area of  ().
• Physical Form: Features a flat antenna design with plastic fingers for direct attachment to T5/T8 tubes.
• Daylight Monitoring: Includes a 24-hour dawn/dusk sensor for smart daylight harvesting.

Control & Configuration

The HC403VRC-KD offers highly granular settings via onboard DIP switches or the HRC-05 remote control (sold separately)l:

• Sensitivity: Adjustable from 10% to 100%.
• Hold-time: Selectable from 5 seconds to 30 minutes.
• Stand-by Period: Supports "corridor function" with intervals from 0 seconds to permanent dimming ().
• Stand-by Dimming: Selectable levels of 10%, 20%, 30%, or 50%.
• Daylight Learning: Supports one-touch learning of ambient lux levels via remote control to set thresholds accurately
