APC by Schneider Electric NBES0309 Rope Leak Detection Sensor Extension Cable
Overview
The NBES0309 is a 6-meter red rope extension cable designed to increase the sensing reach of APC NetBotz rope-style fluid leak detection systems. When your existing sensor rope does not cover the full perimeter of a raised-floor data center, server room, or critical equipment area, this extension lets you chain additional length without adding another controller — keeping your leak detection footprint consistent and your infrastructure protected.
The red jacket color makes routing and inspection straightforward in dense cable environments, and the 6m length is sized for mid-scale coverage expansions around individual rows of racks or equipment bays. For larger deployments, multiple extensions can be daisy-chained as the system allows.
Key Features
- 6-Meter Extension Length: adds approximately 20 feet of rope sensor coverage per cable — enough to span a standard server row or wrap a perimeter equipment bay without needing an additional detection controller.
- Red Cable Jacket: the high-visibility red color distinguishes leak sensor rope from standard power or network cabling at a glance, reducing the chance of accidental disconnection during maintenance or moves-adds-changes.
- 0–45°C Operating Range: covers the typical operating envelope of a conditioned data center or server room (usually maintained between 18–27°C), with headroom for warmer edge environments or partially cooled spaces.
- 0–95% Operating Humidity (Non-Condensing): suited for humid mechanical rooms and raised-floor spaces where condensation risk is highest — exactly where fluid leak detection matters most.
- 3,000m Altitude Rating: supports deployment in high-altitude facilities, such as mountain-region data centers or elevated industrial sites, without derating.
- Compact Form Factor (229 × 51 × 122 mm packaged): ships in a manageable package size that stores easily and routes without bulk along cable trays or under raised floors.
Frequently Asked Questions
Q: What is the NBES0309 used for?
A: The NBES0309 is a 6-meter rope extension cable for APC NetBotz fluid leak detection systems. It extends the sensing reach of compatible rope-style leak sensors to cover larger areas in server rooms, data centers, or mechanical spaces.
Q: How long is the NBES0309 extension cable?
A: The cable is 6 meters (approximately 20 feet) in length.
Q: What color is the NBES0309 rope sensor cable?
A: Red — which helps distinguish it from other cabling in dense installations for easier identification during maintenance.
Q: What is the operating temperature range of the NBES0309?
A: 0°C to 45°C (32°F to 113°F), covering conditioned data center environments and warmer edge or mechanical room conditions.
Q: Can the NBES0309 be used at high altitude?
A: Yes. The NBES0309 is rated for operation up to 3,000 meters altitude, making it suitable for high-elevation facilities.
Q: What humidity levels does the NBES0309 support?
A: Operating relative humidity of 0–95%, which covers the moisture-prone environments — raised floors, mechanical rooms — where fluid leak detection is most critical.
The NBES0309 is the part most facilities teams forget to order until they are already on-site and realize their rope sensor falls two meters short of the drain channel or the row-end where condensate lines run. At 6 meters, it is the right increment for a single rack row extension — not so long that you are coiling excess rope under the floor, not so short that you need two of them end-to-end for a basic perimeter run.
Technical Highlights:
- 6m Cable Length: closes the gap on a standard 10-rack row or wraps a mid-size UPS bay perimeter without requiring an additional leak detection controller — one extension, one connection point.
- 0–95% Operating Humidity: the spec that matters here — rope sensors go where humidity is highest (raised floors, mechanical rooms, near CRAC unit drains), and this rating keeps the cable functional in the worst-case moisture environments it is designed to monitor.
- 0–45°C Operating Range: runs in conditioned spaces but also tolerates the warmer conditions found in edge deployments, co-located mechanical rooms, or facilities running higher ASHRAE setpoints.
Deployment Considerations:
- Route the red rope along the lowest point of the raised floor or perimeter of the equipment bay — fluid pools before it spreads, so sensor placement at floor level determines how early you get an alert.
- The 45°C upper operating limit means this cable is not rated for outdoor or un-conditioned industrial environments; if your ambient regularly exceeds that threshold, verify compatibility with APC before deploying.
Best fit for a data center or server room expansion where an existing NetBotz leak detection zone needs its rope sensor extended to cover a newly added row or equipment bay — a routine facilities task that this 6-meter extension handles in a single cable run.
