General description
Emergency Stop switches are mounted on machines and sections of plant conveyors that cannot be protected by
guards or as a complement to guards. In combination with any dual channel safety monitoring controllers these
switches can be used as emergency stop devices and monitored for up to Category 4/PLe to ISO 13849-1.
The EStrongZ is an emergency stop designed to provide a robust unit in exposed and severe environments.

Function description
The EStrongZ contact block configuration is a 2NC and 2NO and the emergency stop is mounted with 4 x M4
screws from the inside.
The EStrongZ has a special lid that is mechanical linked to the emergency stop safety mechanism. This means that
the safety contacts will open if the lid is removed.
This Emergency stop is made in a total rugged stainless steel 316 body, developed for applications such as food
processing and chemical industry. Since the EStrongZ has a double seal lid gasket and seals, it has an IP69K
enclosure protection and can therefore be high pressure hosed with detergent at high temperature.
As an option the EStrongZ can be ordered with a two colour LED that can be seen easily from a distance.
EStrong Emergency stop switches conform to European Standard EN ISO 13850 and IEC 60947-5-5. They have a
positive mechanical linkage between the switch contacts and the E-Stop Button. The switches are mechanically
latched and can then only be returned to the operational condition by resetting the button as required by
EN ISO 13850.
EStrongZ also exist in a version(EStrongZX) with certified explosion proof contact block. EStrongZX is also in
stainless steel and can be used in European Zone 1, 2, 21,22 enviroments. (Gas and Dust)
