Electromagnetic lock WL4826

for doorglass doorfor industrial applications

Overview
A compact fail-safe electromagnet lock designed for access control installations in commercial and industrial environments. WL4826 operates on 12V DC (compatible with 24V variants), providing a 50–60N holding force for secure door retention. Intended for continuous operation and integration with RFID, keypad and biometric systems.

Main Features

• 50–60N magnetic holding force suitable for light-to-medium duty doors.
• Fail-safe design: power-on to hold, power-off to release for emergency egress.
• No mechanical moving parts — reduced wear and low maintenance.
• Silent operation compatible with office and public-area installations.
• Low continuous power consumption; designed for 12V DC supply.
• Suitable for glass, wooden and metal doors with appropriate mounting brackets.

Applications

• Access control for office doors, staff-only areas and server rooms.
• Retail and public spaces requiring discreet locking solutions.
• Industrial sites, warehouses and production areas requiring controlled access.
• Glass door installations in hotels, banks and commercial buildings (use correct bracket).
• Educational and healthcare facilities for controlled access to labs, pharmacies and records rooms.

Advantages

• Reliable magnetic locking with consistent holding force.
• Quick integration with access control systems (RFID, keypad, fingerprint).
• Long service life due to absence of mechanical wear parts.
• Compact and relatively simple to install compared with complex mechanical locks.
• Silent operation suitable for public and office environments.

Disadvantages

• Requires continuous 12V DC power to remain locked; unlocks on power loss.
• Vulnerability during power outages unless backup power (UPS) is provided.
• Generates heat during prolonged operation; requires correct regulated power supply.
• Precise alignment and correct wiring are required for reliable performance.
• Standard models are not waterproof — limit outdoor use unless a waterproof model is specified.
• Total system cost can increase when including control electronics and backup power.

Troubleshooting & Maintenance

• No magnetic power: verify 12V DC supply, wiring and terminal connections; replace faulty adapter or control unit.
• Door does not lock: check alignment between magnet and armature plate, tighten mounting hardware and ensure contact surfaces are clean.
• Excessive heating: confirm regulated 12V supply and correct current rating; replace unstable power sources.
• Lock won’t release: ensure full power removal, check for residual magnetism and inspect control relay; anti-residual pads may be required.
• Intermittent buzzing/vibration: filter AC ripple, secure mounting and confirm full plate contact.
• Moisture-related faults: use waterproof variants or protective housings and schedule regular inspections.
