ABB dalton m11

Why Choose the ABB Dalton M11?

The ABB Dalton M11 is a compact electromechanical process lock with an integrated ball latch designed for industrial machine guards, doors and hatches. Identified by ABB order code 2TLA020038R3100, it forms part of the ABB Jokab Safety Dalton series and provides electrically controlled guard locking combined with adjustable mechanical retention.

The Dalton M11 operates on 24 V DC and uses an energise-to-lock principle. With the locking signal applied, the ball-catch mechanism is mechanically blocked and provides a holding force of up to 2000 N. When unlocked, the adjustable ball catch provides approximately 25–100 N of mechanical holding force, helping keep a guard positively closed without preventing normal opening.

This M11 configuration uses an 8-pole M12 male connector for power, locking control and status signalling. Dalton itself provides process locking rather than safety-rated guard monitoring, so a separate ABB Eden safety sensor can be installed where safety interlocking is required. Its robust anodised aluminium construction, compact design and status output make the Dalton M11 a practical process-locking solution for automated machinery and industrial guarding.

Key Advantages

• Electromechanical process lock with integrated ball latch.
• Provides up to 2000 N locked holding force.
• Adjustable 25–100 N ball-catch holding force when unlocked.
• 24 V DC energise-to-lock operation suits industrial control systems.
• 8-pole M12 male connector provides convenient plug-in electrical connection.
• Dedicated information output allows the Dalton status to be monitored by the control system.
• Can be combined with a separately installed ABB Eden safety sensor for safety-rated guard monitoring.
• Compact anodised aluminium construction provides excellent durability in industrial environments.

Reliable Process Locking for Machine Guards

Process locking is useful where a machine guard should remain closed during an operating sequence even when the locking function itself is not being used as the safety interlock. The Dalton M11 uses an electrically controlled mechanism to block its ball catch, increasing the holding force from approximately 25–100 N when unlocked to 2000 N when locked.

The Dalton process lock is not itself a safety sensor. Where safety-rated monitoring of the guard position is required, a separate ABB Eden non-contact safety sensor can be installed alongside the Dalton. This arrangement allows the Dalton to manage process locking while the Eden system performs the safety interlocking function, providing a flexible architecture for automated machine guarding.

Typical Applications

• Industrial machine guard doors.
• Robot cell access doors.
• Automated manufacturing systems.
• Packaging and processing machinery.
• Assembly and production equipment.
• Machine access hatches and panels.
• Guarding systems with separate ABB Eden safety monitoring.
• OEM machinery requiring electrically controlled process locking.
