Command and signalling devices
Application:
Command and signalling devices are of great importance for the man-machine interface in the field of industrial applications. They are used, for instance, in control cabinets, control panels, in elevator construction or on conveyor and material handling plants. The manual actuation of the devices starts or stops operating sequences and functional processesThe command and signaling devices of the Ex-R series are particularly suitable for applications in explosive environments and meet the requirements of the zones 1, 2, 21 & 22. The devices are suitable for applications in rough operating conditions and feature large actuating surfaces, which means that they can be operated when the operator wears gloves.
Design and operating principle:
A command and signaling device consists of a device head with mounting flange or illuminated element. The command devices are made of massive brass, the spherical cap of the indicator light or illuminated button of shock-resistant plastic.
The mounting flange has two parts. The mounting of the device heads therefore can be realised independently of the mounting and wiring of the contact and illuminated elements. For each device head, 2 contact elements and 1 illuminated element can be mounted at the most. The mounting flange is designed so that both an incorrect fitting and the de-energisation of the contact and illuminated elements under high mechanical loads is effectively avoided.
