NS E4ZZ1SMK-E42 Pizzato NS series safety locking switch

Why Choose the Pizzato NS E4ZZ1SMK-E42 Safety Locking Switch?

The Pizzato NS E4ZZ1SMK-E42 is an industrial NS series safety interlock switch with guard locking designed for monitoring and controlling access through movable machine guards and protective doors. It combines electronic safety monitoring with a robust locking mechanism for machinery where access must be managed as part of the safety-related control system.

The NS E4ZZ1SMK-E42 provides a substantial 2,100 N holding force, enabling secure retention of the associated guard actuator during operation. This configuration is supplied without an actuator, allowing the appropriate compatible actuator to be selected separately for the installation.

Electrical connection is provided through an M12 connector, supporting efficient installation and servicing on automated machinery. The switch incorporates status indication, uses a durable industrial polymer housing and provides IP67 protection, making it suitable for demanding machine-building, automation and production environments.

Reliable Guard Retention for Industrial Machinery

Guard-locking safety switches are used on machinery where simply detecting whether a protective door is open or closed is not sufficient. The locking mechanism enables the guard to be physically retained according to the machine safety strategy, helping prevent access while hazardous conditions remain present.

With a holding force of 2,100 N, the Pizzato NS E4ZZ1SMK-E42 provides robust mechanical retention for compatible guard arrangements. Its electronic safety architecture, M12 connection and integrated status indication make it particularly suitable for modern automated machinery where guard status must be communicated reliably to the safety-related control system.

Typical Applications

• Machine guard doors requiring monitored locking.
• Robotic cells and automated manufacturing systems.
• Packaging and processing machinery.
• Automated assembly and production equipment.
• Machining centres and guarded machine tools.
• Conveyor and material handling systems.
• Restricted-access production machinery.
• Industrial safety systems using compatible safety controllers or safety PLCs.
