| 1. Wired Recessed Magnetic Contact | Normally closed magnetic reed contact with separate magnet | Concealed installation in wooden, aluminum, or PVC door frames; suitable for new construction | Wired loop; no radio band involved | Powered by the alarm control panel; no local battery required | Typical indoor rating: IP20 to IP44; common operating range approximately −10°C to +55°C | Optional end-of-line resistor supervision; low visual impact; no wireless-jamming exposure | RoHS material compliance should be documented. CE obligations depend on the complete alarm system; a passive contact alone may not require radio conformity assessment | Can be used in systems designed to EN 50131; verify contact construction, tamper supervision, and the system’s declared security grade | Global projects where reliable wired infrastructure is available |
| 2. Surface-Mount Wireless Contact, 868 MHz | Wireless magnetic door contact with external or internal antenna | Surface mounted on residential and commercial doors; useful where cable installation is difficult | 868 MHz ISM band
Common European sub-bands are subject to duty-cycle and power limits | Typically one 3 V lithium coin cell or lithium primary battery; approximately 1–3 years depending on reporting interval and temperature | Typical indoor rating: IP20 to IP44; approximately −10°C to +50°C | Cover-tamper switch, low-battery reporting, supervision messages, and selectable open/close transmission | For the EU, request RED conformity documentation, CE marking information, EMC and radio test reports, and RoHS evidence. 868 MHz operation must match the applicable national sub-band rules | Look for documented EN 50131-2-6 performance and the applicable Grade 1 or Grade 2 system certification; wireless supervision is important for security applications | European Union, United Kingdom, and other markets using compatible 868 MHz allocations |
| 3. Surface-Mount Wireless Contact, 915 MHz | Wireless magnetic contact using a sub-GHz regional radio module | Surface mounting for homes, offices, warehouses, and retrofit security systems | 902–928 MHz region
Exact channel plan and output limits vary by country; 915 MHz is commonly used in North America | Usually one 3 V lithium battery; approximately 1–3 years under normal periodic supervision | Typical indoor rating: IP20 to IP44; approximately −10°C to +50°C | Supervision interval, low-battery alert, cover tamper, and encrypted or authenticated signaling when supported by the control panel | For the United States, verify FCC Part 15 authorization for the complete transmitter configuration. FCC compliance is not interchangeable with CE compliance. RoHS documentation should be requested separately | EN 50131 is not automatically satisfied by using a 915 MHz radio. Request system-level certification and evidence for the specific sensor and receiver combination | United States, Canada, and selected markets using compatible 902–928 MHz rules |
| 4. Long-Range Wireless Contact, 868/915 MHz Variants | Low-power wireless contact with region-specific radio variants | Large homes, outbuildings, warehouses, and sites requiring improved link margin | 868 MHz EU variant915 MHz North American variant
Use separate regional hardware or approved firmware; do not assume one version is globally legal | One or two lithium primary batteries; approximately 2–5 years depending on transmit power, supervision rate, and environmental conditions | Typical indoor rating: IP20 to IP55; approximately −20°C to +60°C for industrial versions | Extended supervision, antenna diagnostics, cover and wall tamper, link-quality reporting, and optional dual-path alarm communication | CE/RED documentation is required for the EU version, while FCC authorization is required for the US version. Check antenna type, firmware, output power, and frequency range in the test report | Suitable only when the sensor, receiver, and complete alarm system have the required EN 50131 documentation; long range alone does not establish a security grade | Cross-border projects that can use region-specific SKUs and maintain separate compliance files |
| 5. Heavy-Duty Surface Magnetic Contact | Robust wired or wireless magnetic contact with enlarged housing and stronger magnet | Metal doors, rolling shutters, gates, industrial doors, and areas with vibration or mechanical movement | Wired version: no radio band. Wireless version: select an approved 868 MHz or 915 MHz variant | Wired version: panel powered. Wireless version: typically a lithium primary battery with approximately 1–4 years of service | Typical outdoor-capable rating: IP65 to IP67; approximately −25°C to +70°C, depending on enclosure and cable gland design | High mechanical tolerance, optional armored cable, tamper loop, end-of-line supervision, and corrosion-resistant mounting hardware | RoHS evidence is relevant for both versions. Wireless models additionally require region-specific CE/RED or FCC documentation. IP rating should be supported by a test report, not only a product label | May be used in EN 50131 installations when the device and alarm system are evaluated for the intended environment and security grade | Industrial, logistics, perimeter, and outdoor applications worldwide |
| 6. Slim Wireless Contact for Narrow Frames | Compact magnetic contact designed for limited mounting space | Aluminum windows, narrow door frames, cabinets, display cases, and interior doors | 868 MHz option915 MHz option
Frequency must be selected according to the destination market | Small lithium coin cell or miniature primary battery; approximately 12–24 months under typical alarm reporting conditions | Typical indoor rating: IP20 to IP30; approximately 0°C to +45°C | Compact tamper design, low-battery alert, periodic supervision, and short magnet gap; installation alignment is critical | Request CE/RED documentation for 868 MHz models and FCC Part 15 authorization for 915 MHz models. Confirm that the tested enclosure, battery type, antenna, and firmware match the supplied unit. RoHS declaration should be current | Verify whether the narrow-frame contact is included in the system’s EN 50131 certificate and whether the specified magnet gap meets the installation requirements | Residential and light-commercial retrofit projects where appearance and space are priorities |
| 7. Smart-Home Door Contact with Multi-Protocol Options | Battery-powered magnetic contact using a standardized smart-home wireless protocol | Residential doors, windows, apartments, and building automation projects | Common variants include 2.4 GHz protocols; some regional security gateways also use 868 MHz or 915 MHz sub-GHz links | Usually one or two alkaline or lithium batteries; approximately 1–2 years depending on protocol, polling, and automation activity | Typical indoor rating: IP20 to IP44; approximately 0°C to +45°C | Open/close status, automation events, low-battery notification, and optional tamper detection; security performance depends heavily on the gateway | For EU radio products, check CE/RED documentation and RoHS evidence. For US radio products, check FCC authorization. A smart-home protocol certificate does not automatically prove EN 50131 compliance | Generally intended for automation rather than certified intruder-alarm systems. Use only with documented EN 50131-compatible equipment when a graded security installation is required | Consumer and light-commercial markets where interoperability and app integration are more important than graded alarm certification |
