When it comes to designing secure enclosures, panels, or access points, the latch you choose is as important as the lock. For engineers and OEMs looking for reliable, vibration-resistant, and space-saving solutions, rotary latches are the go-to choice.
At Eberhard, we’ve been manufacturing innovative access solutions for over a century, and our rotary latches are engineered for performance, durability, and versatility across demanding industries—from heavy-duty trucks and off-highway equipment to military, EV, and industrial applications.
What Is a Rotary Latch?
A rotary latch is a mechanical device that secures a door or panel by engaging a striker and rotating into a locked position. Unlike traditional slam or cam latches, in addition to the single stage latching, Eberhard offers a dual or multi-stage locking mechanism that delivers higher security and prevents accidental opening—even under heavy vibration or impact.
Key Benefits of Rotary Latches
- Compact, Space-Efficient Design - Rotary latches offer high strength in a small footprint. This makes them ideal for tight enclosures, modular designs, or concealed installations.
- High Strength & Vibration Resistance - Thanks to their internal cam and pawl mechanisms, Eberhard rotary latches stay locked even under continuous vibration or shock, making them ideal for vehicles, construction machinery, and military gear.
- Two-Stage and Multi-Stage Latching for Added Safety - Eberhard’s two-stage rotary latches offer a “soft catch” feature—holding the door or panel partially latched before it’s fully closed. This minimizes slamming, protects users and equipment, and provides a secure hold even when the latch isn’t fully engaged.
- Versatile Actuation and Mounting Options
Choose from:
- Remote mechanical cable release
- Electric actuation and sensing
- Manual lever operation
This flexibility allows for smart integration into vehicle interiors, exterior compartments, or automated systems.
- Corrosion Resistance & Harsh Environment Durability - Engineered with high-performance materials and coatings, Eberhard rotary latches stand up to salt spray, moisture, dust, and chemicals. Perfect for the elements—rain or shine.
Ideal Applications for Rotary Latches
- Heavy-duty trucks and service vehicles
- Agricultural and construction machinery
