Why Choose the Pizzato SRBD40ALK Safety Magnetic Sensor?
The Pizzato SRBD40ALK is a robust coded magnetic safety sensor designed for reliable monitoring of machine guards, doors and protective covers in industrial automation systems. Manufactured by Pizzato Elettrica, it belongs to the well-known SR-B safety sensor series, engineered for high safety integrity and consistent performance in demanding environments.
This model is designed for non-contact operation using a coded magnetic actuator, ensuring that the sensor only switches when the correct actuator is present. This provides a high level of tamper resistance and improves machine safety compliance in automated production systems.
The SRBD40ALK is widely used in safety interlock applications where reliable detection of guard positions is required. Its rugged construction and IP67-rated housing make it suitable for harsh industrial environments with dust, vibration and moisture exposure.
Key Advantages
- Reliable coded magnetic safety detection for machine guarding systems.
- High resistance to dust, oil and industrial contamination.
- Non-contact switching reduces mechanical wear and extends lifespan.
- Tamper-resistant operation with coded actuator system.
- IP67 protection for harsh industrial environments.
- Suitable for high-safety automation applications.
Key Features
- Pizzato SR-B series coded magnetic safety sensor.
- Model: SRBD40ALK.
- Coded magnetic actuation system for safety interlocking.
- Typically 2NC safety output contacts (series configuration dependent).
- Actuation distance up to approx. 5–8 mm depending on actuator type.
- IP67 protection rating for dust and water resistance.
- Technopolymer housing with metal reinforcement plates.
- M8 4-pin electrical connection (variant dependent).
Reliable Safety Monitoring for Industrial Machines
The Pizzato SRBD40ALK ensures safe machine operation by detecting the correct position of protective guards and doors. It operates only when paired with its coded actuator, preventing accidental triggering and unauthorized bypassing.
Its non-contact sensing technology eliminates mechanical wear, improving durability and reducing maintenance needs. The sealed IP67 housing ensures stable performance even in environments exposed to dust, moisture, and vibration. {index=1}
