ABB dalton l00

Why Choose the ABB Dalton L00?

The ABB Dalton L00 is a robust mechanical ball-latch unit from the ABB Jokab Safety Dalton process-lock range. Identified by ABB order code 2TLA020038R3000, the L00 version provides the mechanical ball-catch function of the Dalton system without electrical locking, monitoring or connection functions.

Designed for industrial doors and hatches, the Dalton L00 provides a mechanical holding force that helps keep a guard closed without electrically locking it. The ball-catch mechanism provides an adjustable holding force of approximately 25–100 N, making it suitable for applications where a guard needs to remain positively closed during normal operation while still being manually openable when required.

The Dalton platform can be installed alongside ABB Jokab Safety Eden non-contact safety sensors where separate guard-position monitoring is required, although Eden is not included with the Dalton L00 and must be ordered separately. Its compact 80 × 80 × 24 mm construction, anodised aluminium components and straightforward mechanical operation make the L00 a practical solution for industrial guarding applications where electrical process locking is unnecessary.

Mechanical Guard Retention for Industrial Machinery

Machine guard doors and hatches often benefit from a mechanical holding mechanism that keeps them positively closed during normal operation. Unlike an electrically controlled process lock, the Dalton L00 uses only its ball-catch mechanism and therefore requires no supply voltage, control signal or electrical wiring.

Where safety-rated guard-position monitoring is required, the Dalton system can be combined with a separately installed ABB Eden non-contact safety sensor. This allows the mechanical retention function and safety monitoring function to remain separate, providing machine builders with a flexible approach to industrial guarding while avoiding an electrical locking mechanism where one is not required.

Typical Applications

• Industrial machine guard doors.
• Machine access hatches and panels.
• Robot cell guarding.
• Automated manufacturing equipment.
• Packaging and processing machinery.
• Assembly and production equipment.
• Guarding systems using separate Eden safety monitoring.
• OEM machinery requiring mechanical guard retention without electrical locking.
