Optex Passive Infrared Detector

OPTEX RXC-ST Indoor PIR Detector

Overview
The RXC-ST is an advanced indoor passive infrared (PIR) detector built upon OPTRX’s proven RX and CX series. It features OPTEX’s proprietary RX-CORE platform and Digital Quad Zone Logic, delivering exceptional detection accuracy even under challenging conditions. Designed for Grade 2 residential, commercial, and industrial applications.

Key Features

• Digital Quad Zone Logic
  Utilizes 78 densely arranged detection zones. At any point within the coverage area, activation of four or more zones is required before triggering an alarm. The digital CORE platform enhances human detection accuracy while minimizing false alarms from pets.
  

• Advanced Temperature Compensation Logic
  Automatically increases sensitivity in high-temperature conditions—especially in environments around 35–37 °C, where background temperature closely approaches that of human body heat.
  

• High-Density Detection Pattern
  Optimized for precise motion detection to reduce false triggers from environmental factors.
  

• Multi-Angle Mounting Bracket
  Supports wall or ceiling mount with horizontal adjustment of ±45° and vertical tilt from 0° to 15° downwards, offering flexible placement.
  

• Advanced Sealed Optics
  Ensures long-term reliability by protecting against dust, insects, and other intrusion into the optical system.
  
  

• Silent Output
  Employs electronic output without a mechanical relay, ensuring noiseless operation ideal for quiet environments.
