Senba D203B Dual PIR Sensor Alarm System Motion Detector - TO-5 Package
The Senba D203B is a dual-element passive infrared (PIR) sensor in a TO-5 metal can package, designed for high-sensitivity motion detection in alarm systems. It features a wide spectral response and a broad operating voltage range, making it compatible with various 3V to 15V DC security and automation circuits.
Features
- Dual-element PIR sensor for reliable motion detection and reduced false alarms.
- Broad spectral response of 5–14µm, optimized for human body infrared radiation.
- High output signal ≥3500mV (Vp-p) and sensitivity ≥3300V/W for strong detection performance.
- Wide operating voltage range from 3V to 15V DC for flexible system integration.
- Robust TO-5 metal encapsulation suitable for industrial temperature ranges from -30°C to +75°C.

The Senba D203B utilizes a dual-element pyroelectric infrared receiver to detect changes in thermal radiation, typically emitted by moving objects like humans. The matched elements help cancel out common-mode environmental noise, enhancing stability. The sensor’s high detectivity (D* ≥1.4×10⁸ cmHz¹/²/W) and low output noise (<70mV) ensure reliable signal generation for processing by subsequent alarm or control circuitry.
Housed in a hermetically sealed TO-5 metal package, the D203B is built for durability across a wide operating temperature range. Its standardized pinout and voltage requirements allow for straightforward integration into existing PIR-based motion detector modules, security system panels, and automated lighting controls.
