Why Choose the Pizzato SRAL40ALK Coded Magnetic Safety Switch?
The Pizzato SRAL40ALK is a compact coded magnetic safety switch designed for monitoring the position of machine guards, doors, and protective covers in industrial automation systems. It belongs to the trusted Pizzato SR-A safety switch series, widely used in machinery safety applications requiring reliable non-contact detection and high durability.
This model operates using a magnetic sensing principle and is designed to work with a matched actuator (typically SM A01N series depending on system configuration). When the actuator moves out of range, the safety contacts switch state to trigger a safe stop of the machine.
With a rugged technopolymer housing, IP67 protection rating, and a sensing distance of up to 5 mm, the SRAL40ALK is suitable for packaging machines, automated production lines, and general OEM machinery requiring dependable safety interlocking. RatingValue: 4.7
Key Advantages
- Coded magnetic non-contact detection for reliable guard monitoring.
- IP67 protection rating for dust-tight and water-resistant operation.
- 2NC safety contact configuration for secure machine shutdown circuits.
- 5 mm operating distance for flexible installation on machine guards.
- Robust and compact design suitable for industrial environments.
Key Features

Reliable Non-Contact Guard Monitoring
The SRAL40ALK 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 and improves reliability in environments with dust, vibration, and industrial contamination.
Typical Applications
- Industrial machine guarding systems
- Packaging machinery
- Automated production lines
- Material handling systems
- OEM machinery safety interlocking
- General industrial automation safety systems
