The Pilz PIT ESB2.3 CONTACT BLOCK 2 N/C 1 N/O – 400303 is a durable and reliable contact block, designed for use in control and signal devices such as emergency stop (E-STOP) pushbuttons and operator panels. With its robust contact materials, flexible configuration, and compliance with international standards, this component ensures safe, efficient, and long-lasting performance in industrial environments.

At its core, the PIT ESB2.3 provides two normally closed (N/C) and one normally open (N/O) contacts, allowing for flexible integration into control circuits. The N/C contacts are ideal for safety-related functions such as opening a circuit in response to an E-STOP command, while the N/O contact can be used for signalling, feedback, or additional control requirements. This combination ensures that the contact block can serve both safety and operational purposes in a single device.

The contacts are constructed from AgNi (silver-nickel), a material chosen for its excellent conductivity, resistance to wear, and durability under repeated switching. This ensures long service life, even in applications involving frequent actuation, such as safety buttons and operator controls on busy production lines.

Designed for E-STOP applications, the PIT ESB2.3 complies with EN 60947-5-1, a key international standard for low-voltage switching devices. This compliance guarantees reliable performance in safety-critical circuits, ensuring that emergency stop functions are executed effectively and consistently, protecting both operators and equipment.

The unit is designed to operate across a wide ambient temperature range from -30 °C to +85 °C, making it suitable for both cold-storage facilities and high-heat industrial environments. Its robust design is further reinforced by a pollution degree rating of 3, which means it can withstand significant environmental stresses, including dust and industrial contaminants, without compromising performance.

Compact in design and optimised for straightforward installation, the PIT ESB2.3 integrates easily into control panels, pushbutton assemblies, and operator stations. It is particularly valuable in industries such as packaging, automotive, manufacturing, and processing, where reliable emergency stop functions are a fundamental requirement.

In summary, the Pilz PIT ESB2.3 CONTACT BLOCK 2 N/C 1 N/O – 400303 delivers a dependable and versatile solution for E-STOP and operator control devices. Featuring durable AgNi contacts, flexible output configuration, compliance with EN 60947-5-1, and reliable performance across a wide temperature range, it ensures safety, reliability, and long-term durability in demanding industrial environments.
