Product Features
Technical Overview
This motion sensor utilizes passive infrared technology to detect heat signatures from moving objects. The PIR sensor ensures accurate motion detection without false triggers from stationary heat sources. The 24V DC input voltage provides consistent operation, compatible with standard security system power supplies.
The sensor projects a wrap-around U-pattern detection field, extending down and away from the door to inhibit tampering. This pattern design minimizes blind spots and enhances coverage reliability. Electrical connections are straightforward, supporting integration into existing security or access control setups.
This section brings together practical product details such as Wireless Technology, Passive Infrared Sensor (PIR), Input Voltage, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.
Key Product Advantages
The MD-31DOW offers several advantages for security installations. Its adjustable coverage range adapts to different mounting heights, providing flexibility for various door configurations. The tamper-resistant U-pattern projection reduces vulnerability to bypass attempts, ensuring the sensor maintains its protective function.
These strengths make the product easier to deploy and manage in real environments, especially where reliability, usability, and day-to-day operational continuity matter. Notable benefits include Versatile Mounting, Reliable Detection.
Versatile Mounting
Install the sensor on frame headers, walls, or ceilings to suit your space requirements. This flexibility simplifies integration into both new and retrofit security projects.
- Frame Header Mount
- Wall Mount
- Ceiling Mount
Reliable Detection
Passive infrared technology ensures consistent motion detection across the specified coverage areas. The sensor responds quickly to movement, triggering connected security systems promptly.
Deployment / Use Cases
Deploy the SDC MD-31DOW motion sensor in commercial buildings, warehouses, or controlled access areas where door security is paramount. It functions effectively as a request-to-exit sensor, automating door release when authorized movement is detected, enhancing both security and convenience.
Common applications include integration with access control systems for automatic door operation, perimeter security monitoring, and occupancy detection in restricted zones. The sensor's off-white color and compact size make it suitable for environments where aesthetics and space constraints are considerations.
Access Control Integration
Connect the sensor to door controllers or security panels to enable automated entry and exit routines. This reduces manual intervention and improves traffic flow in high-use areas.
Perimeter Security
Use the sensor to monitor doorways or entry points for unauthorized access attempts. Its detection pattern helps cover approach angles, adding a layer of security to vulnerable openings.
Physical Profile
The motion sensor features a slim design with dimensions of 1.50" height, 6.25" width, and 1.50" depth, allowing it to fit discreetly in tight spaces. The off-white finish provides a neutral appearance that complements most interior color schemes. Mounting options include frame headers, walls, or ceilings, offering installation flexibility to match specific architectural layouts.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.50" (38.10 mm), 6.25" (158.75 mm), 1.50" (38.10 mm). This helps confirm rack, shelf, desk, or cabinet fit before installation.
