Why Choose the Pizzato SRAL42ALK Coded Magnetic Safety Switch?
The Pizzato SRAL42ALK is a compact coded magnetic safety switch designed for reliable monitoring of machine guards, doors, and protective panels in industrial automation systems. It is part of the proven Pizzato SR-A safety switch series, widely used in OEM machinery where non-contact safety detection, durability, and tamper resistance are essential.
This model operates using a coded magnetic sensing system and is designed to work with a matched actuator (depending on system configuration). When the actuator moves out of range, the safety contacts switch state, triggering a safe stop of the machine to protect operators and equipment.
With a rugged technopolymer housing, IP67 / IP69K protection rating, and an operating distance of up to 5 mm, the SRAL42ALK is suitable for packaging machines, automated production lines, and harsh industrial environments where reliability is critical. RatingValue: 4.7
Key Advantages
- Coded magnetic non-contact detection for high reliability and tamper-resistant operation.

Reliable Non-Contact Guard Monitoring
The SRAL42ALK 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.
Its non-contact design reduces mechanical wear, improves service life, and ensures stable operation even in environments exposed to dust, vibration, or high-pressure washdowns.
Typical Applications
- Industrial machine guarding systems
- Packaging and bottling machinery
- Automated production lines
- Food and beverage equipment
- Material handling systems
- OEM machinery safety interlocking
