Allen Bradley Non-Contact Safety Switch, Thermoplastic Housing

The 440N-S32016 magnetic safety interlock switch by Allen Bradley Guardmaster offers enhanced guard-locking and safe-access to machinery, helping to reduce downtime and keep your processes running smoothly.

The Sipha range of safety switches feature magnetically sensitive elements which must be activated in a precise order to function correctly. They offer higher security and reliability for complex applications as they cannot be defeated by a simple magnet. This ensures greater tamper-resistance. The Sipha switches are a cost-effective solution which provides performance equal or superior to that offered by mechanical locking units for your safety system.

The 440N-S32016 Sipha magnetically coded switch has 1NC and 1 NO safety contacts and a 10m cable. The sensing distance is 5mm (make), to 11mm (break). This S11 switch has red housing for easy visibility of the unit, which is made of durable moulded ABS plastic. The housing style is S1. The enclosure is sealed to IP67, ensuring that it is dust-proof and can withstand temporary immersion in water. This non-contact interlock switch can be used with hinged, lift-off, and sliding guard doors to provide superior contact-free protection for personnel and equipment.

• Tamper-proof - Magnetic coded sensing ensures excellent level of security
• 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
• Ideal for washdown environments due to high IP67 rating
• Can be mounted in any position

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.
