Securitron -u.s. SAMBD Shear Magnetic Lock 12-24V Dps Bond Sensor

Product Description

The SECURITRON -U.S. SAMBD is a shear-style electromagnetic lock designed for access control applications requiring both holding force and door status monitoring. Operating on 12 or 24 volts DC, the unit integrates a Door Position Switch (DPS) and a bond sensor into a single assembly. The DPS confirms whether the door is in the closed position, while the bond sensor verifies that the magnet and armature are in full contact and generating proper holding force. Licensed electricians and access control technicians are the primary installers of this hardware.

The SAMBD is suited for commercial and light-industrial door openings where shear-type magnetic locking is preferred over surface-mount configurations. Shear locks mount within the door frame and door edge, keeping the hardware concealed and reducing exposure to tampering or mechanical damage. This makes them a common choice for interior doors, glass doors, and high-traffic entry points in commercial facilities. The integrated DPS and bond sensor outputs connect to access control panels or alarm systems to provide real-time door and lock status feedback.

Key Features

• Shear-style electromagnetic locking for concealed, low-profile installation
• Dual voltage operation: 12 or 24 volts DC
• Integrated Door Position Switch (DPS) for door open/closed status monitoring
• Bond sensor confirms full armature contact and active holding force
• Single assembly combines lock, DPS, and bond sensor to reduce wiring complexity
• Sold as a single unit (EA)

Compatibility

Designed as an OEM-style shear electromagnetic lock for commercial access control door assemblies requiring integrated door position and bond sensing outputs.

Installation Notes

Installation should be performed by a licensed electrician or qualified access control technician familiar with low-voltage door hardware. Disconnect power to the access control system before wiring the lock, DPS, and bond sensor leads to the controller. Consult NEC low-voltage wiring requirements and the door hardware manufacturer guidelines for frame preparation and armature alignment. Proper armature seating is critical to achieving rated holding force and accurate bond sensor readings.
