Features of a new series of Ex command devices currently being launched by the steute business division Controltec include flexible and direct integration in machine and plant enclosures within Ex zones 1 and 21.
The Ex ES 97 series is based on the Ex 97 series of position switches. This series is already well established in complex application fields, most particularly explosive zones, and has dimensions to EN 50047.
Switching system
The switching system of this series is extremely robust and durable
The switching system of this series (slow action, 1 NC/ 1NO, positive break NC contact) is extremely robust and durable. The separate terminal compartment to ignition protection class Ex e facilitates the flexible connection of cables directly inside the terminal compartment of the command device.
Thanks to the compactness of the dimensions (installation diameter just 22.5 mm), the Ex command devices are easy to integrate in the surrounding structure.
New Ex command devices
The new Ex command devices are initially available in three versions: with a push button, a latching selector and a standards-compliant emergency stop button. All variants are suitable for use in Ex zones 1 and 21 (gas Ex and dust Ex). Additional actuator variants are available on request.
This Ex ES 97 series perfectly complements the steute Controltec range of command devices for explosive zones. To date, users could choose between the Ex 14 series with connecting cable and the Ex BF 80 in a robust plastic enclosure with a terminal compartment. Now a third option is also available.
