Application

Range of application

Ex command devices are used, for instance, as inspection control and electrical emergency operation devices, as well as shaft control devices for manual command of a lift during maintenance.

Push-button, semi-rotary, key-operated and emergency-stop versions are available. The emergency stop pushbuttons are integrated within the safety circuits of machines and plants. They fulfil the requirements of EN 60204-1.

Design and mode of operation

Our explosion-proof command devices fit in Ø 22.5 mm mounting holes and are suitable for spacings of 30 mm between centres. All Ex command devices provide protection class IP 65, and the devices are doubly insulated to protection class II. The actuator is connected by a bayonet fastener to the EEx 14 switch. Switching elements are available with slow action: emergency stop pushbuttons, pushbuttonswith and without a diaphragm, selectors and key actuators

The Ex command devices presented in this section have the CE marking as per Directive ATEX 94/9/EC from the certified Testing Laboratory EXAM, identification number 0158.
