WLD Connection Cable AB - 2 Meters

The connecting cable between WLD sensor cable and device

The HW group WLD-Connecting cable AB connects a WLD sensor cable (type A or B) to the green WLD zone input of a water leakage device. Important: the connecting cable itself does not detect water – it serves exclusively as a connection path between the actual water-sensitive WLD sensor cable and the WLD device.

Since every WLD zone requires this connecting cable, it is an essential basic component of every HW group WLD installation. It is part of the HWg monitoring ecosystem consisting of sensors, devices and the SensDesk Technology Portal, which provides long-term reliable alarms, charts, PDF reports, an open API and remote management of the devices.

Reliable and early water detection is essential in many industries, for example in data centers. The Water Leak Detection system (WLD system) from HW group is a complete solution designed to protect buildings and facilities from costly water damage.

Connecting piece instead of sensor

The WLD-Connecting cable AB solely provides the electrical connection – the actual water detection is performed by the separately connected WLD sensor cable.

How the WLD-Connecting cable AB is structured

The set consists of a 2-meter long non-sensing two-conductor cable with a green terminal connector and a separate terminator.

How long a WLD zone may be

The maximum total length of a WLD zone depends on the device used.

• The WLD sensor cable itself is available in lengths of 2 m, 10 m or 50 m, with a maximum of 85 m sensing length per zone
• Using the WLD-Extension cable AB, a zone can be extended to a total of up to 185 m
• For NB-IoT devices such as the NB-WLD, the maximum zone length is 60 m
• For WLD2, SD-WLD and the Sensor WLD Relay 1W-UNI, the maximum zone length is 185 m
• Each WLD zone requires exactly one WLD-Connecting cable AB and one terminator at the end of the zone

Part of the HW group WLD system

The connecting cable is used together with other components of the WLD system.

• WLD sensor cable type A: detects water along the entire cable length, available in 2 m, 10 m or 50 m
• WLD-Extension cable AB: extension cable, 5 m, extendable up to 100 m
• WLD2: WiFi/Ethernet water leakage detector for up to 4 zones with WWW, SNMP and PoE
• HWg-WLD: water leakage detector with Ethernet connection for 2D area monitoring via sensor cable
• SD-WLD: IoT monitoring unit for one WLD zone with LAN and WiFi connection, portal required
• NB-WLD: IoT device for one WLD zone with internal battery and NB-IoT mobile network connection, portal required
• Sensor WLD Relay 1W-UNI: universal WLD sensor with one sensor cable input as well as 1-Wire UNI and relay output

The connecting cable is also already included in the combination packages “WLD sensing cable A – 2+2 m”, “2+10 m” and “2+50 m”, but can also be ordered separately.

What is included in the scope of delivery

Please check the scope of delivery upon receipt for completeness and report any missing or damaged parts immediately to your supplier.

• Terminator1 piece

Manufacturer’s warranty

The manufacturer HW group grants a 24-month warranty on the WLD-Connecting cable AB. The housing of the terminal connector is made of plastic.

Connection in a few steps

Connecting the connecting cable is straightforward and requires no additional tools.

1. Insert the green terminal connector of the connecting cable into the WLD zone input of the device
2. Connect the other end of the connecting cable to the WLD sensor cable
3. If necessary, shorten or extend the connecting cable using a standard two-wire cable
4. Place the terminator at the opposite end of the WLD zone
5. Check the total length of the zone according to the device used (60 m or 185 m)
6. Check the zone status in the portal or on the device; the error message “2 = Sensing cable disconnected” indicates a missing or incorrectly installed terminator

Application areas

• Setup and expansion of WLD zones in data centers and server rooms
• Water leakage monitoring in archives, museums and storage rooms
• Hotels and hostels for early detection of water and fire damage
• Industrial facilities with sensitive technical rooms
• Retrofitting or expanding existing HW group WLD installations

The HW group WLD-Connecting cable AB is an unobtrusive but necessary link in every WLD zone: it reliably connects the actual water-sensitive sensor cable to the WLD device and, together with the terminator, ensures correctly functioning zone monitoring.
