Electromagnetic Door Lock in Bangladesh
Electromagnetic (EM) Door Locks are one of the most reliable and widely used locking solutions for modern access control systems. From corporate offices and garment factories to hospitals, schools and data centers organizations across Bangladesh choose EM locks because they are strong, fast, and fail-safe when integrated with RFID readers, fingerprint terminals, face recognition devices or keypads.
Electro Magnetic Lock is suited for Interior Doors, Perimeter Exit Doors and Entrances that require Fail Safe Emergency Release Capability, and meets both security and fire safety requirements for emergency exit doors. Suitable for double leaf metal and wooden doors. The Electro Magnetic Lock is a simple locking device consisting of an electromagnet and armature plate which works purely on the magnetic field, without moving parts, making it fail safe. The Electromagnetic Lock uses an electrical current to produce a magnetic force which securely bonds the energized electromagnet against the armature plate. The Electromagnetic lock is operated by a peripheral device, such as a fingerprint or card reader or keypad. The user is identified and if access is permitted, the power to the lock is automatically turned off and the door is able to open.
What is an Electromagnetic Door Lock?
An electromagnetic door lock is an electric locking device that uses a powered electromagnet to hold a metal armature plate firmly, keeping a door locked. When the power is cut by an access control system (after authentication), the magnetic bond releases and the door opens. This fail-safe operation is a key reason EM locks are common for emergency exit compliance and secure entry systems.

What Affects Electromagnetic Door Lock Price
1) Holding Force (600lbs vs 1200lbs vs 1800lbs)
Higher holding force typically costs more:
-
600 lbs (280kg): common for office doors
-
1200 lbs: for heavier, high-traffic doors
-
1800 lbs+: for high-security areas
2) Single Door vs Double Door Locks
Double door EM locks cost more because they include a longer body and dual locking points.
3) Door Type + Required Brackets
Glass doors and frameless doors usually need:
-
U bracket
-
ZL bracket
-
Mounting accessories
4) Brand & Quality
Bangladesh buyers commonly choose:
5) Monitoring Features
Some EM locks include:
6) Installation, Cabling & Power Backup
A reliable EM lock setup requires:
-
Correct power supply (12V/24V depending on lock)
-
Proper wiring and door alignment
-
UPS/backup power for uninterrupted operation
Why EM Locks are Popular
1) Strong Holding Force (Hard to Force Open)
EM locks are rated by holding force such as 600 lbs (≈280 kg), 1200 lbs, or higher. The stronger the holding force, the more secure the door.
2) Ideal for Access Control Integration
EM locks work smoothly with:
-
RFID card access
-
Fingerprint access control
-
Face recognition terminals
-
Keypad/PIN access control
3) Fail-Safe for Emergency Exits
Many EM locks unlock when power is lost (fail-safe), supporting emergency exit requirements especially important for offices and public buildings.
4) Minimal Mechanical Wear
Because EM locks have fewer moving mechanical parts, they can last longer with less wear.
How Does It Work?
-
The lock consists of an electromagnet and an armature plate.
-
When energized, the electromagnet creates a strong magnetic bond with the plate, keeping the door locked.
-
When power is interrupted (via a switch, keypad, or access control system), the bond breaks, allowing the door to open.
Key Features of Electromagnetic Door Locks
-
High Security – Nearly impossible to force open without power interruption.
-
Fail-Safe or Fail-Secure Options – Can be configured to unlock during power failure (fail-safe) or remain locked (fail-secure).
-
Remote Access Control – Can integrate with biometric systems, RFID, or mobile apps.
-
Durability – No moving parts, ensuring long-term reliability.
-
Quick Release – Instant unlocking for emergency exits.
Types of Electric Door Locks Available in Bangladesh
There are several electric door lock options to choose from, each suited to different needs and budgets.
Magnetic Locks (Electromagnetic)
-
Commonly used in access control systems.
-
Require continuous power to remain locked.
-
Often paired with biometric or card readers.
Strike Locks (Electric Strike)
-
Replace a standard door strike.
-
Operate by releasing the door latch upon authorization.
-
Suitable for office doors and gates.
Smart Locks vs. Traditional Locks
-
Smart Locks can be controlled via smartphones, PIN codes, or biometric inputs.
-
Traditional Electric Locks rely on key cards or mechanical override keys.
Smart systems are trending due to added convenience and remote access features.

How to Choose the Right Electromagnetic Door Lock
Step 1: Identify Door Type and Weight
-
Wooden/metal doors: 600 lbs often works
-
Heavy doors / high traffic: 1200 lbs recommended
-
Glass doors: budget for brackets (U/ZL)
Step 2: Decide Fail-Safe Requirement
If emergency exit compliance matters, use fail-safe EM locks with proper emergency release design.
Step 3: Match Lock Voltage to your Power Setup
Many EM locks support 12V/24V input confirmation before buying. (Your EM-lock listing also notes 12V/24V input.)
Step 4: Plan the Complete Access Control System
A proper system often includes:
Step 5: Choose Supplier Support
For Bangladesh, the best value comes from:
Installation & Maintenance Tips
-
Professional installation recommended: correct alignment is critical.
-
Use proper brackets for glass/frameless doors.
-
Regular testing: check power and holding strength monthly.
-
Backup power (UPS): reduces downtime during outages.
-
Avoid cheap wiring: poor cabling causes voltage drops and lock failure.
Final Thought
Electromagnetic Door Lock is one of the most practical security upgrades in Bangladesh especially when paired with RFID or biometric access control. Price depends mainly on holding force, door type, bracket requirements, and installation quality.
