Electric Strike vs Magnetic Lock for Gate Access

t267-39

An electric strike is a motorized latch fitted to the gate post that releases when powered, while a magnetic lock holds the gate shut with electromagnetic force and releases when power is cut. Strikes suit most swing gates and are more forgiving with alignment, while magnetic locks give a firmer hold but need a precisely fitted metal plate and a dependable power supply.

How an electric strike works on a gate

An electric strike is a small motorized mechanism mounted on the gate post. When the access system sends a signal, the strike opens and frees the latch or bolt on the gate, so the gate can be pushed or pulled open. When there is no signal, the strike stays locked.

Because it works with the existing latch, a strike is usually the simpler retrofit on a swing gate that already has a standard lock. It is also a good match for gates that get heavy use from family members, deliveries and visitors, since the mechanical parts are easy to inspect and service.

How a magnetic lock works on a gate

A magnetic lock uses two parts: an electromagnet mounted on the fixed frame and a steel armature plate on the gate. When power flows, the magnet holds the plate firmly and the gate stays shut. Cutting the power releases the hold immediately.

The main advantage is a strong, even holding force with no moving latch to wear out. The trade-off is that alignment matters a great deal. If the magnet and plate drift apart, the hold weakens, so the installation must be measured and fixed carefully.

Fail-safe or fail-secure: choosing the right behavior

Both devices can be wired fail-safe, meaning they release when power is lost, or fail-secure, meaning they stay locked. This choice matters for safety and for emergencies, and it should be decided together with the installer and whoever manages the property.

Fail-safe suits gates on escape routes or shared entrances where people must get out without a key.
Fail-secure suits gates where keeping the property locked during a power cut is the priority.

Confirm the exact wiring and any local requirements with your installer before finalizing.

Compatibility with access control systems

Most keypads, intercoms, card readers and app-based systems can drive either device, but the power requirements and control wiring differ. Check the voltage, the current draw and whether the access controller includes a suitable relay output.

Also consider the power supply. A magnetic lock typically draws more current to hold than a strike does, and both benefit from a backup battery so the gate still works during short outages. Your installer should size the supply and wiring to match the chosen device rather than guessing.

Installation and weather considerations

Outdoor gates face rain, dust, sun and temperature changes, so the chosen device and its wiring must suit the location. Sealed enclosures, weather-resistant cable and proper grounding all help prevent failures over time.

Gate movement also affects performance. A sagging or twisting gate will pull the latch or magnet out of line. Fixing hinges and checking the gate's alignment before fitting either device usually saves time and callbacks later.

Which one should you choose

For most residential swing gates with an existing latch, an electric strike is the practical and forgiving choice. A magnetic lock is worth considering when you want a firm, clean hold, the gate is well built and stays aligned, and you are prepared for precise installation and a steady power supply.

Frequently asked questions

Is an electric strike or a magnetic lock more secure?

Both provide secure locking when installed correctly. A magnetic lock offers a stronger, even hold, but a strike on a well-built gate is also secure, and overall security depends mostly on installation quality.

Can I use either device on any gate?

Not always. Swing gates with a standard latch usually suit a strike well, while magnetic locks need a gate that stays aligned and a steel plate that can be fitted precisely. A site inspection is the best way to decide.

What happens to the gate during a power cut?

It depends on whether the device is wired fail-safe or fail-secure. Fail-safe releases the gate, while fail-secure keeps it locked, so choose the setting based on your safety and security needs.

Do I need a backup power supply?

A backup battery is recommended so the gate can still open during short outages. Your installer can size the battery to the device's power draw and your expected usage.

Common mistakes to avoid

Choosing a device without checking gate alignment and power requirements is the most common error. Skipping these checks leads to weak holds, unreliable releases and frequent service calls.

Our recommendation

Inspect and adjust the gate before fitting any locking device, and have the installer size the power supply and backup battery for the chosen unit. Decide the fail-safe or fail-secure setting in advance, based on how the gate is used.

Summary

An electric strike suits most swing gates and tolerates small alignment changes, while a magnetic lock gives a firm hold but demands precise fitting and reliable power. Choose based on your gate, your access control system and your safety requirements.
