Hytronik HIM31-SUM Ceiling Mountable Combined Microwave and PIR Motion Sensor for Tri-Level (Corridor) Control

The Hytronik HIM31-SUM is an IP65-rated, surface (ceiling) mountable high-bay motion sensor designed for industrial applications using "Dual Sense" technology, which combines High Frequency (5.8GHz microwave) and PIR sensors. Operating on a 220-240VAC supply, the unit provides 1-10V dimming and supports load ratings up to 1600W resistive or 800VA capacitive.

Technical Specifications

• Detection Range: Provides 360° coverage with a maximum detection area of 18m x 15m (D x H).
• Detection Modes: Offers four programmable logic modes: HF only, PIR only, HF+PIR (Combined for false-trigger prevention), or HF/PIR (Either technology for increased sensitivity).
• Operating Environment: Designed for ceiling mount installations within a temperature range of -20°C to + 50°C.
• Switching Logic: Features zero-cross relay operation to minimise in-rush current, extending the mechanical lifetime of the relay.

Functional Features

• Tri-level Control: Supports "corridor functions" with three levels of light (100%, dimmed, and off) and selectable hold-times and standby periods.
• Intelligent Photocell: Includes a daylight sensor that can automatically switch off fixtures when natural light exceeds programmed thresholds, even if motion is detected.
• Programming: Configuration is performed via an internal 16-channel rotary switch or the HRC-11 infrared remote control (sold separately) for scene selection and fast commissioning.
