Why Choose the ABB EStrongZ Emergency Stop?
The ABB EStrongZ 2TLA050220R0020 is a heavy-duty emergency stop push-button station designed to provide a clearly identifiable means of stopping hazardous machinery in industrial safety applications. Part of the ABB Jokab Safety EStrong series, it combines a highly visible emergency-stop operator with a rugged stainless steel enclosure for reliable use on machinery and production equipment.
This EStrongZ model features a 2NC/2NO contact configuration, providing two normally closed and two normally open contacts for integration into machine safety and signalling circuits. Its enclosure and cover are manufactured from 316 stainless steel, making the unit particularly suitable for demanding environments where durability, corrosion resistance and resistance to frequent cleaning are important.
With IP67 and IP69K protection, three M20 conduit entries and an operating temperature range of -25 to +80 °C, the EStrongZ provides a robust solution for exposed industrial installations. The device can support safety systems up to PL e / Category 4 and SIL 3 depending on the overall safety system architecture.

Reliable Emergency Stopping for Industrial Machinery
Emergency stop devices provide operators with a readily accessible means of initiating a stop command when a hazardous situation occurs. The ABB EStrongZ uses positively operated mechanical contacts within a robust surface-mounted enclosure, allowing its normally closed contacts to be incorporated into an appropriately designed machine safety circuit while the additional normally open contacts can be used for signalling or status functions.
The EStrongZ is particularly suited to demanding machinery installations thanks to its 316 stainless steel construction and IP67/IP69K enclosure protection. When correctly integrated with suitable safety control equipment and system architecture, the device can form part of a safety function achieving up to PL e / Category 4 or SIL 3.
Typical Applications
- Industrial machinery emergency stopping.
- Food and beverage processing equipment.
- Washdown production environments.
- Packaging and processing machinery.
- Conveyor and material handling systems.
- Automated manufacturing equipment.
- Robotic production cells.
- Process machinery and production lines.
- OEM machinery and industrial safety systems.
