ST DL420N10 Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL420N10 ST D Series Safety Sensor?

The Pizzato ST DL420N10 is a versatile ST D series RFID non-contact safety sensor designed for monitoring guards, doors and protective devices on industrial machinery. Its electronic sensing principle eliminates the mechanical contact required by traditional safety switches, helping reduce wear while providing reliable guard-position monitoring on high-cycle automated equipment.

The ST DL420N10 configuration provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This programmable configuration supports flexible integration into modern machine safety architectures, including systems where compatible safety sensors are connected in series and status information is communicated to the machine control system.

Operating from a 24 V DC supply, this version features an integrated 10 m PVC cable with the connection exiting from the left-hand side of its technopolymer housing. The ST D platform provides robust environmental protection for industrial installations, including IP67 / IP69K protection and operation across an ambient temperature range of -25 °C to +70 °C.

Flexible Non-Contact Guard Monitoring for Industrial Automation

The Pizzato ST D series provides electronic non-contact monitoring for movable machine guards and access points. By eliminating mechanically operated contacts at the sensing point, the technology is particularly well suited to high-cycle machinery where conventional safety switches can be subject to repeated mechanical wear.

The ST DL420N10 combines safety inputs and outputs with signalling and programmable functionality, giving machine builders a flexible platform for integrating guard monitoring into automated safety systems. Its integrated 10 m cable provides substantial wiring reach for larger installations, while the sealed construction supports use in industrial environments exposed to dust, moisture and demanding operating conditions.

Typical Applications

• Machine guard and safety-door monitoring.
• Automated production and assembly machinery.
• Packaging and processing equipment.
• Robotic cells and automated manufacturing systems.
• Conveyors and material handling machinery.
• Large machines requiring extended sensor cable reach.
