Control component range for integration with low-profile data entry systems
9 March 2005, Switches, Relays & Keypads

Rafi claims to be the first supplier to develop a control component range with an extremely small depth behind panel of 9,2 mm which makes it suitable for combined installation together with short-travel keys and other components on the same PCB. The RAFIX 22 FS system comprises actuators and contact blocks. The actuators (pushbuttons, keylock and selector switches, signal indicators and emergency stop) are fastened on the front panel with a ring nut into a 22,3 mm panel cut-out according to IEC 947. The cast-on collar seal made of thermoflex material and an integral special sealing guarantee a water-jet proof degree of protection IP65. The contact blocks are soldered onto the PCB which can also accommodate other system components such as short-travel keys, electronic components or displays.

Illumination of the actuators is provided by a 3 mm LED inserted and soldered into the base of the contact block. The PCB is fastened to the front panel with bolts, with the contact blocks sliding completely into the actuators. This makes the complete system extremely flat. Other advantages are: contact blocks do not need to be wired individually as a result of the PCB mounting method and the PCB with the short-travel keys and the electronic module does not need to be cut out for the control components.

The contact blocks are provided with gold contacts and designed for low voltage (42 V, 250 mW max). The following contact arrangements are available: one NC, one NO, two NC, two NO, one NC and one NO. The NC contacts are positive opening according to EN 609 47-5-1 and can be used for emergency stop functions.
