These are Industrial Sealed Keyboards which can be connected to a computer directly as the switches are programmed to give an ASCII code through a PS2/USB output. The Industrial Sealed Keyboards can be customized as per requirement not only by way of size, shape, number of switches, etc., but by even programming each switch to give a customized code. SBL has tied up with Sprintek USA who offer different type of ICs/EEPROMs that can offer various types of configurable PC based keyboards. Industry : Industrial Electronics, Process Controls, Defense Equipment, etc. Applications: PLCs, CNC based Machine Tools, Special Purpose Machines (SPMs), Defense Applications, etc. Technology : PC based keyboards are programmed to offer ASCII codes by using special ICs/EEPROMs. These ICs/EEPROMs are programmed to offer the code as per customers’ requirements. These Chips can configure up to 256 switches and can also control 128 LEDs. SBL offers both the Hardware (interface cards) and the software programming required in customized versions. Besides offering the PC based keyboard switches, Sealed Touchpads are also offered to make an integrated PC based Sealed Keyboards with Touchpad. Overview Industrial processes are now controlled more and more by computer systems. All such computers used are usually located in Shop Floor environments, which by any standards tend to be unclean. Normal switch keyboards used to operate such systems are always affected by the harsh environments in the Shop Floor area. SBL therefore offers a Industrial Sealed PC compatible keyboard which can with stand these harsh conditions prevailing on Shop Floors or other areas. The Keyboard is similar in construction to the Snap Dome Sealed Keyboard. It is housed in an IP55 grade enclosure and can be used as a desktop device. Keyboards with out enclosures can also be provided for direct assembly on the Panels. Besides the standard 104 switch keyboard (with Trackpad) SBL can also customize the layouts and size of such keyboards. SBL also offers the freedom of using customized ASCII codes to suit every requirement.   Features Replaces the normal ASCII Keyboard with respect to the software, dimensions, circuits, legends, etc. No complicated fitments or programming is required. Just plug in the PS2/USB socket into the Keyboard port and it's ready to use! Industrial grade components used to withstand harsh environments. Multiple data entry protection provided. Auto reset facility offered. IP55 Grade Enclosures offered. Function Keys can be programmed as per Customer's requirements. Additional function keys can be offered.

Metal Keyboards are made using stainless steel material or aluminium which makes them very tough and can be used in very harsh environments. The switch elements are embedded inside the stainless steel or aluminium due to which they are completely protected from any external abuse. Thus these are also termed as vandal proof keyboards.

Keyboards having illuminated switch areas are commonly termed as Illuminated Keyboards. Illumination can be of two types – entire switch area or only for the text/legends. Illuminated is achieved by using a light source under the switch. In most of the cases, illuminated push buttons made by reputed manufacturers like Omron, Rafi, etc. are used. Industry : Consumer Electronics, Process Controls, Access Controls, Machine Tools, etc. Applications: Special Purpose Machines (SPMs), Water Dispensers, Elevators, Ultra Sound Machines etc. Technology : Illumination is achieved by using LEDs under the switches. The Overlay can be of different materials like Polyester, Metal Caps, Silicon, etc. where the illuminated portion is made translucent of semi-transparent to allow the light to pass through. Illuminated Keyboards can be made by using snap domes, or push buttons where the LED is inbuilt in the switch self. These switches are assembled on a separate PCB which is then mounted behind the Overlay Panels and sealed. However, Illuminated Keyboards using snap domes can be made only by using a silicon material as the Overlay. Overview Illuminated Keyboards can be used in all types of environments especially where the equipment has to be used in areas of low lighting. They are also used in systems where it is necessary to highlight the functions in operation by illuminating the respective switches. These include Medical Devices, Access Controls, Machine Tool Controls, Elevators, as well as Defense applications.   Features Illumination of Key Switch areas as well as for text/legends. Various colour illuminations offered. Illuminated keyboards using Polyester, Silicon, Metal Caps can also be offered.

The working of these capacitive switcheskeyboards is based on Charge Detector (CD) technology. When any user touches the key switch area the capacitive charge from the user’s body is detected by a specially developed circuit, and the signal is passed on to the system. The solid state nature of the circuit makes the life of such a switch virtually infinite.

These Capacitive Switch Panels are operated by just touching them with our fingers. As the Capacitive Switch Technology used is based on a solid state circuit, the life of these switches is virtually infinite and will last the life time of the product in which they are used. Capacitive touch switches can be offered on any di-electric panel like Plastic, Glass, Wood, Granite Tiles, etc. The Capacitive touch circuit can be embedded in the di-electric material itself so that the Capacitive switches remain unaffected by harsh environments. The switches can be offered as Momentary or in Latching mode. (Toggle). Industry : Medical Electronics, Process Controls, Hotels/Hospitality Sector, Consumer Electronics, etc. Applications: Medical Devices: Capacitive Touch Switch Module for Hospital Beds, Capacitive Touch Sensor switches for Patient Monitoring Systems, Remote Touch Switches, etc. Elevator Controls: Capacitive Push Button Switches, In-Car Capacitive Switch Keyboards, etc. Access Controls: Capacitive Proximity Sensor Switches, Capacitive Switch Keyboards, etc. Lighting Controls: Capacitive Light Switches, Capacitive Touch Dimmer Switches, Capacitive Touch On/Off Switches, etc.  Electrical Appliances: Capacitive Touch Switches for Cooking Ranges, Capacitive Switch Keyboards for Refrigerators, Capacitive Remote Switches for Air Conditioners, etc. Technology : The Capacitive Switch Technology is based on Charge Detector (CD) Technology. When any user touches the key / switch / sensor area the capacitive charge from the user’s body is detected by a the Capacitive Switch circuit, and the signal is passed on to the system. The solid state nature of the circuit makes the life of such a switch virtually infinite. Overview Capacitive Touch Switches are one of the most versatile switches as they can be operated by a mere touch of the finger. As the Capacitive touch circuit can be embedded in any di-electric, it makes them impervious to all external factors like temperature, dust, humidity etc. As the Capacitive Touch Switch module does not have any contacts, the switches can easily last a lifetime. This has made Capacitive switches very popular in consumer electronics (Ipod), Kitchen Appliances (Cooking Ranges), Access Controls (Door Openers), Process Controls (Elevator Buttons), etc.   Features Infinite Life Toggle Switching Operations.
