Are you sourcing reliable Computers & Tablets for demanding industrial environments? Compel supplies industrial computers, rugged tablets, and panel PCs engineered for automation and field operations. Unlike consumer-grade hardware, our units withstand high vibration, temperature swings, and dust. We support your deployments with essential installation accessories. This includes IP65 junction boxes, TVS diodes, and secure wire connectors.
Procuring your computing hardware and integration components from a single distributor simplifies your supply chain. Compel ensures you get verified industrial-grade specifications. This reduces system downtime and streamlines your maintenance operations.
Choosing Between Fixed Industrial Computers and Mobile Rugged Tablets
Your deployment environment dictates the hardware form factor. Fixed workstations, such as panel PCs, are ideal for stationary machinery monitoring and human-machine interface applications. Rugged tablets excel in field diagnostics, inventory management, and mobile inspections where technicians need portable data access.
- Select panel PCs for permanent mounting in control cabinets or production lines.
- Choose rugged tablets with high-ingress protection ratings for mobile field service.
- Ensure compatibility with existing low-voltage wiring systems using standard 18-24 AWG connectors.
Matching Ingress Protection and Thermal Specs to Your Environment
Industrial computing hardware must survive dust, moisture, and extreme temperatures. When installing systems in washdown areas or outdoor locations, look for high IP ratings. You can also protect external connections and auxiliary boards by housing them in dedicated IP65 polycarbonate enclosures.
- Use IP65 rated enclosures to protect external wiring connections from high-pressure water jets and dust.
- Verify the operating temperature range of your computing equipment, especially in unconditioned spaces.
- Install thermoplastic-housed connectors with silicone seals for secure, moisture-resistant connections.
Protecting Communication Ports and Sensitive Electronics from Surges
Industrial computers connect to various sensors, actuators, and power lines that are prone to electrical noise and voltage spikes. Implementing circuit protection on these communication lines is critical to prevent processor damage. Utilize transient voltage suppression (TVS) diodes on data lines to clamp unexpected voltage surges.
- Select TVS diodes from the P6KE series to handle peak pulse power up to 600W on sensitive data lines.
- Match the diode standoff voltage to your system operating voltage to avoid leakage current.
- Use fast-switching Schottky and rectifier diodes like 1N5819 or 1N4007 for reverse-polarity protection on power input lines.
Buying guide
Choosing Computers & Tablets
- What IP rating do I need for computers and tablets used in wet processing environments?
- For wet processing or outdoor washdown areas, choose devices or enclosures rated at least IP65. This rating ensures complete protection against dust ingress and low-pressure water jets from any direction. If the equipment faces temporary submersion, look for IP67-rated housings and connectors.
- How do I choose the correct TVS diode to protect my tablet's USB or serial communication ports?
- Select a TVS diode with a reverse standoff voltage slightly higher than the port's normal operating voltage, such as 5V or 12V. Ensure the clamping voltage is lower than the maximum voltage the port transceivers can tolerate. The P6KE series offers fast clamping times and handles up to 600W of peak pulse power to safeguard sensitive inputs.
- What wire gauge is recommended for powering low-voltage industrial computer terminals?
- Most low-voltage industrial terminals and control circuits utilize wiring between 18 AWG and 24 AWG. You can use T-type or lever-action wire connectors to make quick, tool-free power splices for solid or stranded copper conductors. Always verify that the connector's current and voltage ratings exceed your power supply output.
- Why should I select polycarbonate over standard ABS for industrial computing enclosures?
- Polycarbonate offers superior impact resistance, UV stability, and a higher flammability rating (typically UL94 V-0) compared to ABS. This makes it the preferred material for outdoor deployments or harsh factory floors where physical impacts and temperature fluctuations occur. It maintains structural integrity and seal quality over longer service lifespans.
