CapTouch+ProxySense HMI Solutions
Bring your interface to life by incorporating intelligent Capacative Touch (CapTouch) + Proximity Sensing (ProxySense) technologies within your assembly.
>Custom designed to your specification
>Manufactured in the UK at our Fareham,Hampshire, Factory
>We can supply the interface alone through to a fully assembled unit.
>We can take care of the HMI, electronics and enclosure
From a single switch location to a keyboard of 16-20 keys or more, we use projected capacitive sensing for best reliability and repeatable detection.
Proximity function can operate at 20-40mm distance (programmable) and groups of buttons could be illuminated to assist in low light conditions, or to indicate that the equipment has sensed a hand/finger near the pad(s). Individual outputs for proximity or grouped.
Keys can be latching/toggle or momentary function.
Sliders and rotary wheels can be incorporated (sliders typ 50 to 75mm length) to give an analogue function with a cap panel.
Low supply current (uA) & low current indicators possible for battery powered systems panels with a single master ON/OFF touchpad, and ability to switch into a ‘sleep’ / low current mode can be designed for a battery powered design that needs a dedicated power up/down output line.
Thicker window material can be used for impact resistance.
Can be used with tactile membrane keys incorporated onto the same panel.
Housing design can incorporate low cost replaceable cover acrylic for maintenance/repair.
Toughened glass can be used for high durability applications, for instance as a surround for a TFT or display with dedicated cap buttons.
We offer an SPI interface or direct logic output for interfacing to a host processor.
Supply, typ 3.3v from the host, Indicator LEDs from single, bi colour to RGB can be incorporated.
Auto calibration feature continuously adjusts the sensing to allow for long term changes in the environment and results in very stable outputs.
Sealed front panel, can be reverse mounted to front panel (non conductive is best, front panels utilizing metal/conductive components can be used with careful design).
Backlit Membrane Keypads-Embedded LEDs
Side Firing LED
Flexible Polyester (PET) or Flexible Kapton (FPC)
Background & Technical:
Create full & selective backlighting by incorporating Side Firing LEDs into a flexible Membrane Keypad. Ideal for light sensitive environments and applications where consistent diode emission is required for prolonged periods of time. Low operating temperature & power consumption, long life cycle and full customization make embedded LEDs an increasingly popular backlighting solution.
No limits on X & Y dimensions. Maximum thickness 1mm
Shared characteristics with standard Membrane Keypads
Range of LED colours including white, blue ,red, orange,green,yellow plus bi-colour and tri-colour combinations.
Embossed or Non Embossed
Tactile or Non Tactile
Full, gradient and selective backlighting options including switch positions.
Seemless backlighting, no shadow or witnessing from domes.
Backlit Membrane Keypads-Light Tile
RGB LED Light Tile
FR4 Rigid PCB
Background & Technical:
Create full & selective backlighting by incorporating RGB LED Light Tiles onto your PCB Keypad Assembly (PCBA). Ideal for light sensitive environments and applications where consistent diode emission is required for prolonged periods of time. Low operating temperature & power consumption, long life cycle and full customization make RGB Light Tiles an increasingly popular backlighting solution.
Maximum size of 700 x 700 x 3mm.
Hard wired to PCB board (2 x wires) with the light tile being adhered or screwed into position on the PCBA.
Can be manufactured to allow for mechanical fixtures & components on the PCBA and designed to fit around available land on the board.
No background noise like other backlighting solutions such as Electroluminescence (EL).
Further enhancements to the light effect can be achieved by adding selective tinting and secret-til-lit prints to the Graphic Overlay.
Typical Power Requirements Yellow, Red, Amber or Green LEDs: LED operation voltage circa 2.0V. Current circa 10mA~15mA no more than 20mA.
Blue or White LEDs: LED operation voltage circa 3.0V. Current circa 10mA~15mA no more than 20mA.
Other colours available.
