SR AD42ALK Pizzato Magnetic safety sensor

Why Choose the Pizzato SRAD42ALK Coded Magnetic Safety Switch?

The Pizzato SRAD42ALK is a compact coded magnetic safety switch designed for monitoring the position of machine guards, safety doors, and access panels in industrial automation systems. It belongs to the reliable Pizzato SR-A safety switch series, widely used in machinery safety applications where non-contact detection and high reliability are essential.

This device uses a coded magnetic sensing principle, meaning it only responds to its matched actuator. This helps reduce tampering risks while ensuring consistent safety performance in automated production environments such as packaging machines, assembly lines, and industrial equipment.

With a rugged technopolymer housing, IP67 / IP69K protection rating, and compatibility with multiple contact configurations (commonly 2NC or 1NO+1NC variants), the SRAD42ALK is designed for demanding industrial environments requiring reliable, maintenance-free operation. RatingValue: 4.6

Reliable Non-Contact Guard Monitoring

The SRAD42ALK provides non-contact monitoring of safety guards using a coded magnetic system. When the actuator moves out of range, the safety contacts open and trigger a safe stop in the machine control system.

This design reduces mechanical wear, improves durability, and ensures stable operation in environments where dust, vibration, or contamination would affect traditional mechanical switches.

Typical Applications

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