SR AD42ALK-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SRAD40ALK-A01N Coded Magnetic Safety Switch?

The Pizzato SRAD40ALK-A01N is a compact coded magnetic safety switch with actuator designed for monitoring the position of machine guards, doors, and access panels in industrial automation systems. It is part of the reliable Pizzato SR-A safety switch series, widely used in machinery safety applications requiring non-contact detection and high operational reliability.

This model uses a coded magnetic sensing system, ensuring the switch only responds to its matched actuator (SM A01N). This helps prevent tampering while maintaining safe machine operation by triggering a safety stop when a guard is opened.

With a durable technopolymer housing, IP67 protection rating, and a standard actuation distance of up to 5 mm, the SRAD40ALK-A01N is designed for demanding industrial environments such as packaging machines, automated production lines, and general machinery safety systems. RatingValue: 4.6

Reliable Non-Contact Guard Monitoring

The SRAD40ALK-A01N operates using a coded magnetic system that detects the presence of its matched actuator. When the actuator moves out of range, the safety contacts open, sending a signal to stop the machine safely.

This non-contact design reduces mechanical wear, improves durability, and ensures stable performance even in dusty or vibration-heavy industrial environments.

Typical Applications

• Industrial machine guarding systems
• Packaging machinery
• Automated production lines
• Access doors and safety covers
• Material handling systems
• General industrial safety interlocking
