The 440N-S32017 Sipha Magnetic Safety Interlock Switch offers secure contact-free machine guard locking to improve protection for equipment and personnel and keep your machine processes running efficiently.

The versatile Sipha safety switches feature magnetically sensitive elements which must be activated in a specific order to operate correctly. This gives them a high level of tamper-resistance as they cannot be defeated by a simple magnet, providing greater reliability and security for complex applications. These cost-effective switches ensure performance equal or superior to that offered by mechanical locking units for your safety system.

The 440N-S32017 Sipha Magnetic Safety Switch has 1NC/1NO safety contacts, a 10m cable and an S2 enclosure made of durable ABS plastic. The switching distance is 9mm (make), 12mm (break). It is dust-proof and water-tight, with a high IP67 rating (NEMA 6P). This makes it ideally suited for use in wash-down environments. The switch can be used with hinged, sliding, and lift-off machine guards.

The Sipha sensor must be connected to the control unit to give a monitored circuit. The control unit can be used with a single sensor to provide a high-integrity system for high risk applications. It has facilities for connecting a manual reset button and monitoring external devices such as contactors.

• Can be mounted in any position for application flexibility
• Tamper-proof - Magnetic coded sensing ensures excellent level of security
• Easy to install and versatile due to compact size and moulded-in brackets
• Must be operated with its own safety control unit
• Non-contact actuation ensures less wear-and-tear and longer service life

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.

Non-contact safety switches are highly reliable and durable. They take less wear and tear and are low-maintenance, as well as resistant to shocks and vibrations. They cannot be easily manipulated or tampered with and are ideal for use with machine guard doors to restrict access to unsafe areas. They are often used in industrial environments, such as in factory production lines.
