Key features

• 12th gen Intel® Alder Lake mobile CPUs (Intel Core i7-12700H default; Core i9 optional)
• 15.6-inch 4K (3840x2160) PCAP touch panel with optical bonding and anti-glare
• Optional MXM discrete GPU modules (NVIDIA/Intel options)
• Dual hot-swappable batteries for continuous field operation
• Magnesium-alloy chassis with double-injection molding for drop protection
• Front-side IP65 protection; MIL‑STD durability options

Durability & certifications
Designed for harsh environments: optical bonding and anti-glare for sunlight readability, magnesium-alloy enclosure with reinforced molding, and tested to MIL-STD-810H (shock, vibration, drop). Front-side IP65 rating ensures resistance to dust and water jets. MIL‑STD‑461G EMC options and CE/FCC certifications are available.

Performance & expansion
Platform supports high-performance mobile Intel CPUs, multiple memory and storage configurations, MXM graphics modules for GPU acceleration, and additional storage bays for field upgrades. Typical memory options range from 8+8GB up to 32+32GB; storage options include up to 2TB SSD plus secondary bay.

Connectivity
Comprehensive I/O for field deployments: WLAN, Bluetooth, optional WWAN (4G/5G), GNSS (GPS/GLONASS), 2 x RJ45 Gigabit LAN, 1 x USB-C (ALT/PD as specified), multiple USB-A ports, DB9 serial (RS232/RS422/RS485 switchable), HDMI 4K output (optional), Micro SDXC and Nano SIM slot.

Battery & power
Dual hot-swappable 11.55V typ. 3220 mAh Li‑Ion batteries (2 x) deliver extended runtime; typical standard battery operating time is approx. 11 hours under specified test conditions. AC adapter supports global input (100-240V, 50-60Hz) and system power varies by configuration (adapter examples: 240W / 20V DC).

Optional GPU & accelerators
