Allen Bradley Guardmaster 440N-S32042 Sipha Magnetic Non-Contact Safety Switch Optimise the safety of your machine guard door and protect operators with the Sipha Magnetic Safety Switch by Allen Bradley Guardmaster. This versatile safety switch ensures a high level of tamper-resistance as it features magnetically sensitive elements which must be activated in a specific order to operate correctly. This means that it cannot be defeated by a simple magnet, providing superior security and reliability for complex applications. The 440N-S32042 Sipha Non-Contact Safety Switch has a supply voltage rating of 250VAC, 300VDC. It has 1NC/1NO safety contacts and 1NO auxiliary contact. It is dust-proof and water-tight, with a high ingress protection rating of IP67 (NEMA 6P). This compact interlock safety switch also features moulded-in brackets and offers simplified installation. The Sipha switches are ideally suited for use 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. Features and Benefits: • Tamper-proof - Magnetic coded sensing ensures excellent level of security
• Mounting is possible in any position
• Non-contact actuation ensures less wear-and-tear and longer service life
• Must be operated with its own safety control unit
• Easy to install and versatile due to compact size and moulded-in brackets
• IP67 rating makes it perfectly suited for wet environments Certifications: IP67 rated

TUV approved 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. What are the advantages of non-contact safety switches? 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.
