This state-of-the-art sensor operates on passive infrared technology, which means it detects changes in infrared radiation emitted by living beings and objects, making it an ideal choice for security applications where traditional lighting may not be practical or desirable.

The 94A40 detector is compact in size, measuring approximately 6.3 inches by 3.3 inches by 1.6 inches, allowing for easy installation in various environments. Its rugged construction, with an operating temperature range of -40 F to 140 F (-40 C to 60 C), ensures reliable performance even in extreme climates.

The sensor in this PIR motion detector, specifically the 90R35 model, boasts superior motion detection capabilities. It features a wide 110 detection angle in the horizontal plane and a 45 detection angle in the vertical plane, enabling it to cover a broad area while minimizing false alarms. The sensor's adjustable sensitivity settings allow users to customize the device to their specific requirements, ensuring optimal performance in various environments.

This PIR motion detector is designed for easy integration with other security systems and can be connected to alarm devices, such as sirens or strobe lights, for enhanced security. It also includes a built-in test function, allowing users to verify the device's proper operation at any time.

In summary, the Electro-Optics 94A40 Passive Infrared Motion Detector with the 90R35 sensor is a versatile and powerful security solution. Its advanced passive infrared technology, wide detection angle, adjustable sensitivity settings, and rugged construction make it an ideal choice for various security applications where the ability to detect motion in complete darkness or low light conditions is essential.

The 94A40 passive infrared (PIR) motion detector with a 90R35 sensor is a popular choice for security applications due to its ability to detect body heat and motion in the dark. Here are some pros and cons of buying this specific model:

1. Passive Detection: The 94A40 uses passive infrared technology, which means it doesn't require any external power source or light to operate. This makes it ideal for use in remote areas or locations where power is not readily available.

2. Wide Detection Angle: The 90R35 sensor has a wide detection angle of 90 degrees, allowing it to cover a larger area with a single unit. This can help reduce the number of detectors required to secure a given space.

3. Adjustable Sensitivity: The 94A40 allows users to adjust the sensitivity level of the sensor, which can help minimize false alarms caused by pets or other small animals.

4. Weather-resistant: The housing of the detector is weather-resistant, making it suitable for outdoor use in various weather conditions.

5. Easy to Install: The 94A40 is relatively easy to install, as it doesn't require any wiring or external power source.

1. Limited Range: The detection range of the 94A40 is relatively limited, with a maximum range of about 10-15 feet, depending on the ambient temperature and other environmental factors.

2. Sensitivity to False Alarms: While the adjustable sensitivity feature helps reduce false alarms, it may not completely eliminate them. The sensor can be triggered by external heat sources, such as cars passing by or animals in the vicinity.

3. Limited Compatibility: The 94A40 may not be compatible with all security systems, and users may need to purchase additional components or adapters to integrate it with their existing setup.

In conclusion, the 94A40 passive infrared motion detector with a 90R35 sensor is a reliable and effective option for security applications in areas with limited power sources and a need to cover a wide detection angle. However, it may not be suitable for larger areas or applications where a longer detection range is required. Additionally, users may need to adjust the sensitivity settings to minimize false alarms and ensure accurate detection. Overall, the benefits of using this detector, such as passive detection, wide detection angle, and easy installation, outweigh the limitations, making it a worthwhile investment for many security applications.
