1. Sensor Anatomy
- High-strength ABS plastic outer casing.
- Jeweller 868 MHz radio circuit with AES encryption.
- LED indicator for alarms, tamper and signal.
- High-precision magnet and reed detector.
- Integrated anti-opening tamper.
- CR123A lithium battery (approximate lifespan of 5–7 years).
- Internal antenna optimized for up to 1200m in open space.
2. Types of Ajax sensors
- Standard magnetic contact : detects opening/closing of doors and windows.
- With vibration and tilt detection : adds impact and displacement sensing.
- Motion sensors : PIR for indoor and outdoor areas.
- Smoke or leak detectors : extend protection beyond unauthorized access.

4. Applications and return on investment
- Private homes : deterring intruders at minimal cost per unit.
- Offices and SMEs : integration into Ajax systems for remote monitoring.
- Shops and warehouses : early detection of unauthorized access; reduces losses due to theft.
- Estimated ROI : investment recovered by preventing a single incident of theft or damage, which usually exceeds €100 in many markets.
5. Certifications and standards
- Compliant with CE and RoHS for safety and environmental protection.
- Grade 2 certified according to EN 50131 standards for residential and light commercial environments.
- Data encryption with AES-128 and mutual authentication.
- Compliant with ISO/IEC 14443 for control of external cards and modules.
6. How to choose the optimal sensor
- Evaluate the distance between the sensor and the hub (choose a model with appropriate range).
- Determine if you need an auxiliary input for external contacts.
- Define the security level: for high-risk environments, ensure Grade 2 or higher.
- Check the temperature and humidity of the installation location (0 °C – 50 °C, humidity ≤ 75%).
- Check the battery life according to your preferred maintenance plan.
7. Frequently Asked Questions
Can I use this sensor outdoors?
No, it's designed for indoor use only.
Can they be mixed with other manufacturers?
They only work with compatible Ajax hubs (Hub, Hub Plus, ReX).
How do I avoid false alarms from slight vibrations?
Adjust the sensitivity threshold in the Ajax app.
