SL500 Micro Shearlock (Maglock)

The SL500 Micro Shear Lock is a high-security electromagnetic locking solution designed for use with access control systems, door entry systems, intercom systems, and electronic security installations. Suitable for commercial, industrial, educational, healthcare, residential, and public sector environments, it provides exceptional holding force whilst maintaining a compact and discreet installation profile.

A shear lock combines the holding strength of an electromagnetic lock with a mechanical shear locking mechanism that provides enhanced resistance to forced entry. When the door closes, the armature aligns with the lock body and is secured through both magnetic attraction and mechanical shear resistance, delivering significantly higher holding force than many conventional magnetic locks.

Operating from 12VDC or 24VDC, the SL500 provides an impressive holding force of up to 2,600lbs (1,200kg) in shear. The lock features an adjustable locking delay from 0.5 to 25 seconds, allowing sufficient time for the armature plate to align correctly before the shear mechanism fully engages. It also incorporates COM, NO and NC monitoring contacts for integration with compatible access control and monitoring systems.

Frequently Asked Questions

What is a micro shear lock?

A micro shear lock combines electromagnetic holding force with a mechanical shear locking action, providing enhanced resistance to forced entry whilst maintaining a compact installation profile.

What holding force does the SL500 provide?

The SL500 provides up to 2,600lbs (1,200kg) of holding force in shear.

Why does the SL500 have an adjustable locking delay?

The adjustable locking delay allows the door and armature plate sufficient time to align correctly before the lock fully engages, helping ensure reliable and consistent operation.

Is the SL500 fail safe?

Yes. The SL500 operates as a fail-safe shear lock, meaning it releases automatically when power is removed.

What are the COM, NO and NC contacts used for?

The COM, NO and NC monitoring contacts provide status feedback for compatible access control and monitoring systems.

What voltage does the SL500 operate on?

The SL500 operates from 12VDC or 24VDC power supplies.

Can the SL500 be used with access control systems?

Yes. The SL500 is compatible with access control systems, door entry systems, intercoms, keypads, card readers, emergency release devices and other electronic security equipment.

Is there a fire-rated version available?

Yes. A dedicated FR-SL500 Fire Rated Micro Shear Lock is available for applications requiring tested fire-door suitability and associated fire certification.
