Ensure that your guard-locking system is complete with the 440K-A21030 Semi-Flexible Actuator and Alignment Guide by Allen Bradley Guardmaster.

The 440K-A21030 is a Semi-Flexible Actuator and Metal Alignment Guide which is designed for use with the Elf and Cadet 3 GD2 Safety Interlock Switches. This actuator is made of tough stainless-steel to ensure high reliability and durability. The alignment guide allows the switch and actuator to be applied in more demanding applications.

Semi-Flexible actuators can be used in operations where the actuator enters the switch at an angle and are suitable for use with tight angles. The angle can be adjusted on the actuator. Semi-Flexible actuators move in a single plan direction only. The Semi-Flexible key also allows the safety switch to be used on smaller radii doors.

This specially profiled actuator should be permanently fixed to the safety guard. It can then be inserted into the safety interlock switch to achieve secure guard-locking for your machinery. The Elf and Cadet 3 safety switches provide superior protection for personnel and equipment by ensuring safe-access in dangerous areas.

Safety Interlock Switches are locking devices which can be used to monitor the position of a machine guard door and turn off the power supply when the safety barrier is released. They can also be used to keep a guard securely locked when machinery is running. This helps to prevent personnel from accessing a hazardous area where machinery may be in motion and minimises risk of injury or equipment damage. Interlock switches are often used for industrial applications.

The actuator is a separate component which is usually inserted into the switch to enable the locking mechanism to work. It forms a key part of the overall safety interlock unit. Different types include: 90º, Flat, Standard, Semi-Flexible, Fully Flexible, and Specialty.

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.
