SR AL40AN2 Pizzato Magnetic safety sensor

Why Choose the Pizzato SRAL40AN2 Coded Magnetic Safety Switch?

The Pizzato SRAL40AN2 is a compact coded magnetic safety switch designed for monitoring the position of machine guards, doors, and protective panels in industrial automation systems. It belongs to the reliable Pizzato SR-A safety switch series, widely used in OEM machinery where non-contact safety detection, durability, and high reliability are required.

This model operates using a magnetic coded sensing system and is designed for use with a matched actuator (typically SM A01N depending on system configuration). When the actuator moves out of range, the safety contacts switch state and trigger a safe shutdown of the machine.

With a rugged technopolymer housing, IP67 protection rating, and an operating distance of up to 5 mm, the SRAL40AN2 is suitable for packaging machinery, automated production lines, and general industrial environments requiring dependable guard interlocking. RatingValue: 4.7

Reliable Non-Contact Guard Monitoring

The SRAL40AN2 uses a coded magnetic system to detect the presence of its matched actuator. When the guard is opened or the actuator moves out of range, the safety contacts open and the machine is safely stopped.

This non-contact design reduces mechanical wear, improves reliability, and ensures stable operation even in dusty, vibrating, or industrial environments.

Typical Applications

• Industrial machine guarding systems
• Packaging machinery
• Automated production lines
• Material handling systems
• OEM machine safety interlocking
• General industrial automation systems
