Waarom Keypado jouw keuze is
Rugged Metal Construction for High-Use Locations
The enclosure can be produced from stainless steel, cold-rolled steel, aluminum, or another customer-specified metal according to the application environment. A reinforced body, rigid faceplate, protected fasteners, and concealed internal components help improve resistance to impact, tampering, vibration, and unauthorized access. Surface options may include brushed stainless steel, powder coating, painted steel, or custom color finishes. Keypado can also develop the enclosure around your required dimensions, cable entry position, mounting pattern, wall box, panel cutout, and installation clearance.
Weatherproof Protection Against Dust and Moisture
For outdoor and industrial installations, the telephone structure is designed to minimize water and dust entry through the faceplate, keypad, handset connection, cable glands, and enclosure joints. Sealing materials, gasket design, drainage considerations, and protected cable routing are selected according to the required application. IP65, IP66, or another target protection level may be considered where appropriate, subject to final design verification and testing. Typical applications include parking facilities, gate entrances, transport infrastructure, industrial plants, public areas, and exposed service locations.
Analog, SIP/VoIP, and Cellular Communication Options
The telephone can be configured for connection with an analog telephone line, SIP/VoIP network, or cellular communication system such as GSM, 3G, or 4G. Depending on the selected platform, available functions may include DTMF dialing, hotline operation, auto-dialing, emergency call control, ringdown communication, PoE, external DC power, and remote system integration. Keypado can match the internal PCB, connectors, wiring, and power architecture to your existing communication infrastructure. Final protocol compatibility and network requirements should be confirmed before production.
Durable Keypad and Application-Focused Controls
The user interface can include a stainless steel numeric keypad, full metal keyboard, emergency push button, Braille markings, backlit keys, or a simplified hotline control panel. Key legends, tactile response, illumination, actuation force, and layout can be adjusted for security entrances, correctional facilities, elevators, parking systems, public telephones, industrial equipment, or self-service installations. The keypad and internal wiring are assembled to support reliable operation in frequent-use environments. Protective finishing and function testing help ensure that each unit matches the approved sample and project specification.
From Application Requirements to Production-Ready Telephones
Keypado follows a controlled customization process to convert your communication and installation requirements into a reliable finished telephone.
1. Application Review and Technical Requirement Confirmation
We begin by reviewing the installation environment, communication platform, mounting method, operating frequency, user interface, power source, and expected usage conditions. Our engineers confirm whether the project requires analog, SIP/VoIP, GSM, 3G, or 4G communication, as well as hotline, auto-dialing, emergency button, backlit keypad, or special labeling functions. Environmental factors such as dust, water, corrosion, vandalism, temperature, and cleaning methods are also considered before the design is finalized.
2. Industrial Design, Drawing, and Sample Development
After the requirements are confirmed, Keypado prepares the enclosure structure, faceplate, keypad layout, handset position, cable entry, mounting holes, and internal component arrangement. Production drawings, cutout dimensions, wiring diagrams, finish specifications, and interface details are reviewed with the customer. A prototype or pre-production sample can then be produced for installation testing, user evaluation, communication verification, and design approval before mass production begins.
3. Metal Fabrication and Surface Treatment
Approved metal sheets or cast components are processed through cutting, stamping, CNC machining, bending, welding, deburring, and surface preparation according to the product design. The enclosure may then receive brushed finishing, polishing, powder coating, painting, laser marking, or other specified treatment. Special attention is given to edge quality, flatness, mounting accuracy, hole position, sealing surfaces, and finish consistency. These steps help ensure that the telephone fits correctly and maintains a professional appearance in its final installation.
4. Electronic Assembly and Functional Testing
The keypad, handset, hookswitch, PCB, communication module, connectors, wiring harness, power components, and accessories are installed according to the approved configuration. Each unit can be checked for dialing, voice transmission, receiving quality, keypad response, handset operation, button function, indicator or backlight performance, power input, and network connection. Where required, inspection may also include enclosure fit, sealing interfaces, grounding continuity, and verification against customer drawings and test requirements.
5. Final Inspection, Packaging, and Delivery
Before shipment, finished telephones are inspected for appearance, dimensions, labeling, fastener installation, cable routing, accessories, and functional performance. Packaging is selected to protect metal surfaces, handset assemblies, faceplates, and electronic components during international transportation. Keypado can provide approved samples, inspection records, wiring information, installation instructions, and customized product documentation according to the project scope. Production quantities, lead time, and delivery arrangements are confirmed based on the final design and order requirements.
