Benefits
With IP65/IP67 sealing, M12 connectors, and operation down to -40°C, the MRU400iX installs directly on forklifts, conveyors, and rail vehicles where standard readers cannot survive.
The onboard Linux edge computing platform lets you deploy custom applications on the device itself, eliminating the need for a separate server or gateway at every read point and reducing network dependency at the edge.
The integrated circularly polarized antenna reads tags in any orientation out of the box. An external antenna port with adjustable output power extends coverage when a wider or longer read zone is required — without adding a second reader.
