Control and monitoring devices with external contact blocks

norelem is expanding its portfolio by adding control and monitoring devices with external contact blocks. Designed for the safe triggering of switching commands and the clear display of operating, status, and fault messages, the buttons are used in such fields as mechanical and plant engineering, automation technology, the process and manufacturing industry, and construction technology. Their unique feature: actuators and contact elements can be combined to individual requirements.

In industrial applications, control and monitoring devices serve as the central interface between man and machine. They allow for controlling such functions as start and stop or changing the operating mode, while simultaneously indicating states of operation and faults.

The new control and monitoring devices are distinguished by their robust construction, durability, and high protection ratings. They can be combined with various contact and light elements and integrated effortlessly into switch boxes, machines and systems.

The devices are composed of an operating element/indicator (button, switch, and light) and an external contact block (NO/NC contact) with a modular design. This design provides a clear separation between actuation and contact technology and supports flexible device configurations. The elements can be combined as needed and exchanged independently of one another. This facilitates assembly and maintenance as well as customisation to different application requirements. Buttons, switches and indicator lights are suitable for mounting holes with a diameter of 22.3mm.

The control devices are available as push-buttons standard and illuminated, as standard selection switches latching or momentary, as illuminated selection switches latching or momentary, as standard indicator lights, and as key-operated switches latching or momentary. Also available for the push-buttons are individual labelling signs with standard symbols and texts.

In addition, norelem offers membrane buttons for such sensitive areas as medical and laboratory technology as well as the food industry and similar, hygiene-relevant applications. Their closed, robust surface protects against dirt, dust and moisture and allows for easy cleaning and disinfection.
