Installation checks
Confirm the iM9 connection, pinout and configuration before installation. The listing says the cable can be extended but gives no maximum extension length. Verify the proposed cable run with the supplied sensor documentation.
Outdoor use is stated in the original listing, but a specific IP rating is not provided. Check the enclosure, connectors and mounting conditions for the installation. The original page includes no downloadable specification PDF or dimension drawing, so confirm mechanical fit before making a mounting bracket.
