The Lantronix WMB-EDCA is the wall mount bracket made for the EDCA-DIO-01 Enclosure Door Contact Alarm. It is a mounting accessory, not a sensor. Its job is to hold the EDCA-DIO-01 in a fixed position on a wall, so the alarm unit is not left loose next to the enclosure it monitors. For engineers specifying door-open alarms on equipment enclosures, it is the part that completes a wall-mounted EDCA-DIO-01 installation. Lantronix lists two compatible products on the WMB-EDCA page: the EDCA-DIO-01 Enclosure Door Contact Alarm and the 22365 Magnetic Contact Alarm Switch. The OCA-P181610 appears as a related product. Lantronix files the bracket under switch accessories in its network infrastructure catalog, the same part of the catalog that covers its network switches. Lantronix does not publish dimensions, weight, material or fastener details for the WMB-EDCA, and the product page lists no technical specifications. The EDCA-DIO-01 product brief is the only document linked from the bracket's page and is the reference for the alarm unit the bracket carries. Check that brief when planning the mounting location and wiring of the alarm. Some documentation for this part may still show the Transition Networks name, because Lantronix acquired Transition Networks in August 2021.
