The PM351 is a 4-inch keypad Android 11 mobile computer in which the scan engine, keypad, memory, and LTE come bundled by SKU. The 1D-only SE965 model has no camera, and the alphanumeric keypad is only on SE4100 engine models, so match the combination before ordering.

4 GB/64 GB is available only on the SE4710 numeric keypad Wi-Fi model (SKU 7), and LTE models use 1 micro SIM. The camera is an 8 MP unit on top next to the scan engine rather than on the back, which makes it easy to switch from scanning straight to taking photos.
Operating temperature by engine
The upper operating temperature limit differs by engine. Models with the 1D engine (SE965) are -20 to 60°C, and models with 2D engines (SE4100, SE4710) are -20 to 50°C.
About 5 minutes of battery hot swap
When the 3.63 V 4,800 mAh battery is removed, the screen turns off and it switches to hot swap mode; data is kept for about 5 minutes while the red LED stays on. Inserting a new battery returns it to its previous state without rebooting. Spare batteries charge up to 4 at a time in the 4-slot battery cradle (4SBC), and the single-slot cradle charges the unit and 1 battery together.
Drop and tumble test standards
It withstands repeated 1.5 m drops to concrete across the full operating temperature range (MIL-STD 810G), and it has passed 500 tumble cycles at 1 m (1,000 impacts) and a repeated drop test of 10,000 drops from 0.2 m onto a wood floor. It is rated IP65.
The model with Android 13 and Wi-Fi 6E on the same body is the PM352.
