The Rittal AX 2577010 is a plastic handle for latch locks of type AX and KX, equipped with a safety insert and locking E1. It serves as an alternative to the standard lock insert and can optionally be used with or without a safety cylinder insert. The handle is designed for use in industrial enclosures and housings, where secure and user-friendly operation of locks is required. Version A enables universal mounting on various housing types, while locking E1 is specifically designed for applications where the key can only be removed when the lock is secured.

Applications

The handle is primarily intended for use in industrial environments, particularly in enclosures, control cabinets, and other closed housings requiring secure access. It is used in electrical, automation, and IT infrastructure systems, where access control and prevention of unauthorized openings are critical. Locking E1 ensures that the key can only be removed when the lock is secured, enhancing security and preventing accidental opening.

Functions and Equipment in Detail

The handle consists of a housing made of glass-fiber-reinforced polyamide, providing high mechanical strength and resistance to mechanical stress. The locking nose is made of plastic, the seal of polyurethane (PU), ensuring a tight seal against dust and moisture. The clamp piece is made of galvanized steel sheet, offering corrosion protection and durability. The handle color is RAL 9011, a neutral gray tone that integrates well in industrial environments.

Technology Explained Simply

Locking E1 is a special locking mechanism where the key can only be removed when the lock is secured. This prevents the lock from being accidentally opened while the key is still in the lock. This feature is especially important in systems where access to electrical or electronic components must be strictly controlled. The plastic handle is designed to rotate easily to open or close the lock, with materials selected for long service life and high load capacity.

Compatibility and Accessories

The handle is specifically designed for AX and KX locks and can be mounted on these housings. The locking nose AX and KX allows adaptation to different lock variants. Mounting is done using the included fastening screws. When used in a housing with multiple latches, note that only one handle 2577.010 with locking E1 can be used per housing. For a second latch, handle 2533.100 without locking can be used to maintain functionality.

Mounting and Installation

Installation involves securing the clamp piece to the housing wall using the included screws. The locking nose is inserted into the lock, and the handle is placed onto the locking nose. The seal ensures a tight seal between the handle and the housing. Installation requires no special tools, only a screwdriver or pliers for securing the screws.

Operational Advantages

The handle provides a secure and reliable locking solution that controls access to sensitive components. The materials ensure high mechanical strength and long service life, even under industrial conditions. Locking E1 enhances security, as the key can only be removed when the lock is secured. The RAL 9011 color ensures visual harmony with other components in the enclosure. The product is delivered with all necessary mounting components, so no additional parts need to be purchased.
