Product information

Description

The SATEL B-2FL magnetic contact sensor is a cylindrical reed switch designed for monitoring doors and windows in burglar alarm and access-control systems. Its compact cylindrical form factor with magnetic activation enables discreet installation on frames and sashes to detect opening and closing. The sensor supports simple wiring in either normally-closed or normally-open configurations and integrates with standard alarm panels and security devices.

Advantages

The cylindrical design allows the sensor to be recessed or surface-mounted in narrow spaces, reducing visibility while maintaining reliable magnetic contact operation. The reed switch mechanism provides stable state detection with low power consumption and no moving electronic parts, contributing to long service life and minimal maintenance. Compatibility with both NC and NO wiring makes the sensor flexible for different system requirements.

Suitable for (tasks / use cases)

  • Perimeter security monitoring of doors and windows in residential or commercial premises
  • Integration with burglar alarm panels to trigger alerts on opening or forced entry
  • Access control systems requiring status feedback from doors or gates
  • Discrete installations where visible sensors are undesirable

Key specifications

  • Type: cylindrical magnetic contact (reed switch)
  • Operation modes: normally-closed (NC) and normally-open (NO) wiring supported
  • Mounting: designed for installation on frames and sashes, suitable for recessed or surface mounting where dimensions allow
  • Compatibility: for use with standard alarm control panels and security input circuits
  • Power: passive magnetic reed switch — requires no separate power supply for the sensor element
  • Construction: durable enclosure for indoor use with low-maintenance mechanical design

How to use

Install the SATEL B-2FL sensor so the cylindrical body and the matching magnet are aligned when the door or window is closed. Choose NC or NO wiring according to the alarm panel input requirements and connect the sensor leads to the appropriate circuit. For recessed mounting, prepare holes in the frame and sash to accommodate the cylinder and magnet; for surface mounting, ensure the components are positioned to maintain reliable magnetic coupling across the closed gap. Verify correct operation with the alarm panel by opening and closing the protected opening and confirming the expected input state changes.

Usage recommendations

Place the sensor components within the manufacturer’s recommended gap tolerance to avoid false alarms; ensure wiring is routed to prevent physical strain. Use the normally-closed option where tamper or wire-cut detection is required. Periodically inspect mounting and alignment during maintenance checks to preserve reliable detection.
