Locks for automatic warehouses

Locks for automated warehouses are locking components designed to integrate with automated vertical and horizontal storage systems-motorized drawer warehouses, carousels, pedestal cabinets, lift systems, and robot-operated shelving. In these contexts, the lock presides over access to pick bays, service compartments, maintenance panels and storage drawers, having to ensure reliability even over very high opening and closing cycles and in environments subject to continuous vibration.

The OMR catalog for this application includes 33 models, selected to meet the typical needs of automatic system designers and integrators: quick locking, standardized profiles, compatibility with thin metal panels, and the possibility of centralized key management.

Standard impression latches – Quarter-turn latches with triangle 6, triangle 5 (also in Ø19 version), square 7 and double barb – 3 mm Pin are available in basic, extension and horseshoe clip versions. They cover most panel configurations found in commercial automatic systems. The adjustable cam version allows the cam protrusion to be matched to the actual panel clearance, ensuring precise locking with no residual play.

Stainless steel impression latches – For systems installed in environments with high humidity, metal dust, or subject to frequent cleaning with harsh detergents, stainless steel latches in triangle, triangle with status indicators, double barb – 3 mm Pin, screwdriver, and hexagon variants offer corrosion resistance and long service life.

Adjustable locks-Adjustable shape models (triangle 6, double barb – 3 mm Pin, screwdriver, and hexagonal) are designed to absorb assembly tolerances typical of mass production: the cam adjusts in the field without tools, reducing assembly time and in-line nonconformities.

Universal Wafer Cam Locks – The Ø18, Ø19, micro-lock, stainless rotor, square jig, and oversized head models complete the offering for those who need differentiated keys or systems ammaestr able on multiple access doors.

Push-button handles – The push-button handle and horseshoe clip version combine quick keyless opening and positive locking: suitable for frequently accessed picking compartments where operational speed is a priority.

Push-button lock and tubular lock-Two solutions for access with differentiated security requirements complete the catalog: the push-button lock for quick locks with manual release, and the tubular lock for increased break-in resistance on the key.

How to choose the right lock for your automatic system

Choosing the right lock for an automated warehouse means starting with an analysis of the specific application: system type, access frequency, number of operators, and installation environment. Here are the main criteria.1. Frequency of use and resistance to cycles
Automated systems may require hundreds of openings per day on pick or maintenance compartments. In these cases, it is essential to choose locks designed for a high number of cycles. Quarter-turn latches with cam mechanisms and universal wafer-cylinder cam locks are the most suitable types, due to the simplicity of the mechanism and robust construction. Avoid latch mechanisms on compartments with very high opening frequency.2. Speed of access vs. security
  • Quick access without a key: the push-button handle is the ideal solution for operational picking compartments, where speed matters more than security.
  • Controlled access with standard key: socket key locks (triangle, square, screwdriver) allow one universal key to be used for all system panels-a relevant operational advantage in environments with many operators.
  • Restricted access: universal wafer- or pin-cylinder cam locks, combined with a training system, allow differentiated levels of access between operations personnel and maintenance technicians.
3. Assembly tolerances and mass production
In mass-assembled systems, cumulative tolerances can cause backlash or interference on locking. Adjustable socket key locks (triangle 6, double barb - 3 mm Pin, screwdriver, hex) solve this problem downstream of assembly, without the need to rework the panel. They are the recommended choice for medium- to high-volume productions.4. Panel thickness and type of fastening
Automatic system panels are often made of thin sheet metal (1-3 mm). Always check that the length of the lock shank is compatible and that the fastening system-standard nut, horseshoe clip, or quick fastener-is accessible at the back of the panel. When rear space is limited, horseshoe clips are the most practical solution.5. Environment and maintenance
  • Clean and indoor environments: brass or die-cast metal, with routine maintenance standards.
  • Environments with moisture, dust or chemicals: prefer stainless steel versions, which do not require additional surface treatment and resist industrial detergents.
  • Food or pharmaceutical environments: contact OMR's technical department to evaluate solutions with materials certified for food contact or with no lubricants.

FAQ

Which locks are best suited for picking compartments in an automated warehouse?

It depends on the frequency of use and the level of security required. For very frequently accessed compartments without stringent security requirements, the push-button handle is the quickest choice. If key-controlled access is required, standard socket key locks (triangle 6 or square 7) allow one universal key to be used on all system panels.

What are "adjustable" locks and when should they be used?

Adjustable latches have a cam that can be positioned at multiple angles to match the actual panel clearance. They are particularly useful in mass production, where cumulative machining and assembly tolerances can cause inaccurate locking or residual backlash. In OMR models, adjustment is made without additional tools, directly during assembly.

Can custom locks be obtained for systems with special requirements?

OMR has been manufacturing locks since 1958 and controls the entire production process of the products it markets, so we can confidently answer that our company is ready to meet specific and project-based requests.
