Satel OPXM-1-B magnetic contact in sealed housing — SATEL OPXM-1-B

Satel OPXM-1-B magnetic contact in sealed housing is a wired magnetic switch designed for monitoring doors and windows in intrusion detection systems. The device features a hermetically sealed enclosure that protects internal components from dust, moisture and other environmental factors, making it suitable for perimeter protection and locations with demanding conditions. As a wired sensor from SATEL, it offers a compact form factor and a tamper-resistant design for reliable signal transmission to control panels.

Advantages

The sealed housing ensures long-term reliability by preventing ingress of water and contaminants, reducing failure risk in outdoor or humid installations. The magnetic contact provides stable and immediate state changes when a protected opening is operated, supporting accurate alarm and monitoring response. The unit is compatible with standard wired alarm systems and includes tamper resistance to detect unauthorized access to the sensor body.

Suitable for

• Door and window monitoring in residential and commercial buildings
• Perimeter and gate protection in outdoor or semi-exposed locations
• Areas with high humidity, dust, or other harsh environmental conditions
• Integration into wired intrusion detection and access control systems

Key specifications

• Type: Wired magnetic contact in hermetic/sealed housing
• Operation: Reed/magnetic switch activation for open/closed state detection
• Environmental protection: Sealed enclosure for resistance to moisture and dust
• Mounting: Surface-mount design suitable for doors, windows and frames
• Tamper: Built-in tamper detection to signal enclosure opening or removal
• Connection: Low-voltage wired interface for direct connection to alarm control panels
• Dimensions: Compact form factor for discreet installation in standard openings

How to use

Install the magnetic contact so that the actuator magnet aligns with the sensor body when the door or window is closed. Route the low-voltage wiring from the sensor to the alarm control panel following the manufacturer's wiring diagram and local electrical standards. Secure the sealed housing in place using appropriate fasteners and ensure the tamper switch is active. After wiring, test the sensor by opening and closing the protected opening to confirm correct state reporting and tamper operation on the control panel.

Usage recommendations

Place the sensor where the sealed housing will not be exposed to direct mechanical impact. For outdoor or wet locations, verify cable entry points are sealed and routed through suitable conduit. Periodically inspect the mounting and wiring integrity and test the contact operation as part of routine system maintenance to ensure continued reliability.
