Didactum Magnetic Contact Sensor

The Didactum Magnetic Contact Sensor is an essential tool for access monitoring and burglary protection in sensitive areas. Whether server rooms, data centers, control cabinets, or critical infrastructure facilities – it precisely registers the opening and closing of doors, windows, racks, or gates and reports these events in real time to the Didactum IT monitoring system.

Server Room Monitoring & Access Management

Server rooms must be reliably protected against unauthorized access. The magnetic contact sensor detects whenever a door or server rack is opened. In combination with a server room alarm system, automated actions can be triggered such as:

• Immediate e-mail notification
• SMS alerts via GSM/LTE gateway
• SNMP traps to tools such as PRTG, Nagios, or Zabbix
• Activation of sirens or strobe lights
• Linking with video surveillance systems

Integration into Didactum Monitoring & Building Technology

The magnetic contact sensor connects to a potential-free input (Dry Contact IN). Thanks to AutoSense, it is automatically detected and displayed in the WebGUI. Configurable settings include:

• Normal state: “open” or “closed”
• Setting of individual alarms in case of deviations
• Event log and syslog recording for audits
• Integration into SNMP v1/v2c/v3 monitoring systems

Installation & Flexibility

• Easy installation: sensor and magnet mounted parallel on the door or window frame
• Mounting options: screws or double-sided adhesive tape
• Compatibility: with all Didactum monitoring systems
• Range: cable lengths up to 500 m
• Flexible orientation: horizontal or vertical installation possible

Typical Applications

• Server room monitoring: door and rack access detection
• Access control: detection of unauthorized entry via doors, gates, or windows
• Intrusion detection: reliable forwarding of alarms to security staff
• Technical rooms: tamper detection in energy and control systems
• Archives & warehouses: access protection for sensitive documents or goods
• Remote sites: monitoring unmanned remote facilities

Advantages of the Didactum Magnetic Contact Sensor

• Fast alerting when access changes occur
• Easy integration into Didactum monitoring systems & third-party solutions
• Syslog & event logging for audit-compliant reporting
• Flexible use at doors, windows, racks, and gates
• Long distance capability with up to 500 m cabling

Practical Examples

• Server room: immediate alert in case of unauthorized rack or door access
• Industrial environment: detection of unscheduled openings of control cabinets
• Data archive: tamper protection for critical document rooms
• Power facilities: safeguarding substations and technical enclosures
