Pushbuttons suit handheld applications, says Rafi
Pushbuttons and illuminated pushbuttons are available from Rafi Compact that are particularly suitable for handheld control devices or applications that require robust switching a low profile.
The Lumotast pushbuttons and illuminated pushbuttons are for 16.2mm mounting holes. The compact devices provide distinct haptic feedback. The series allows for individual labelling options, to create customer-specific user interfaces. Lumotast 16 pushbuttons have an external diameter of only 22.3mm and fit in 25 x 25mm arrays. They take up very little space inside the housing and have a mounting depth of only 18mm.
The Lumotast 16 series provides a range of compact pushbuttons and emergency stop pushbuttons. Complementing the illuminated pushbutton range, the series also includes different types of emergency stop pushbuttons: an innovative active/inactive version for detachable or wireless control units has a translucent plastic mushroom head that lights up red when properly connected to the emergency stop function of the machine/system. When inactive, the mushroom is colourless and cannot be mistaken for an e-stop according to DIN EN ISO 13850.
The series also has conventional emergency stop pushbuttons with one or two NC contacts or two NC and one NO contact. Installing the devices takes mere seconds: once inserted into the mounting hole, they are attached by a single threaded nut behind the housing front panel. They can easily be connected via 2.8 x 0.5mm quick-connect terminals. Bezels are available in six colours according to EN 60073, to clearly show what function has been assigned to a switch. The C-LAB variant additionally offers coloured or Lumotast 16 pushbutton series metallised front rings. C-LAB legend inserts and bezels allow for customer-specific labelling of the pushbuttons. Rafi can also supply Lumotast 16 pushbuttons with customer-specific printing upon request. The switch contacts use high-quality gold contacts to ensure precise switching in harsh environments in the long term, says Rafi.
Emergency stop pushbuttons for large currents are available with silver contacts. All pushbuttons and e-stops feature IP65/IP67 ingress protection.
The Lumotast 16 kill switch changes its colour to red only when its emergency stop function is active
