Do you have a question about the OX-600 and is the answer not in the manual?

Assuming this OX-600 device will be powered with 24VDC, is the sensor to be mounted on a single gang rough in box or ring with rear wiring entry, or is the wire inlet on the outside of the sensor and to be piped in surface mounted?

The OX-600 main unit is compatible with a JIS single switch box, which suggests that it can be mounted on a single gang rough-in box with rear wiring entry. However, if using an installation board (optional), additional space must be secured for sliding installation. The manual does not explicitly state whether surface mounting with an external wire inlet is required, but it provides details on securing installation space and battery replacement space for certain configurations.
