The APC temperature and humidity sensor AP9335TH is an Eingebaut sensor for monitoring the environment in data centres and network rooms. It serves as a universal sensor for measuring temperature and humidity, and is specifically designed for use with compatible NetBotz appliances. The measurement data is transmitted via a wired connection, with the sensor connecting to the system through an RJ-45 connector. The cable length is 3.9 metres, allowing for flexible placement within the room. Extension using standard CAT5/6 cables is possible, with a maximum reach of up to 30 metres, facilitating installation in larger rooms or hard-to-reach locations.

Applications

The sensor is intended for use in data centres and network rooms, where precise environmental monitoring is required to ensure the operational safety of IT infrastructures. It enables continuous monitoring of temperature and humidity values, which are critical for avoiding overheating, condensation, or other environmental risks. Integration into existing environmental monitoring systems requires no additional configuration, as the sensor is automatically detected by compatible NetBotz appliances.

Functions and Equipment in Detail

The sensor features an integrated temperature and humidity sensor that continuously measures environmental conditions. The measured values can be transmitted over the network, enabling central monitoring and documentation of environmental conditions. Each sensor can be individually configured with a unique name and location to allow precise assignment of measurement data. Installation is tool-free using plastic mounting brackets, enabling quick and easy mounting in rack systems. Additionally, the delivery includes mounting accessories such as a 203 mm cable tie, a 25.4 mm mounting plate, a housing clip, two 19 mm cable holders, and six wire clamps to ensure secure and orderly cabling.

Technology Explained Simply

The transmission of measurement data occurs via a wired network through the RJ-45 connector, which is standard in IT networks. The cable length of 3.9 metres provides sufficient flexibility for placing the sensor at various locations in the room. Extension using CAT5/6 cables allows the range to be extended up to 30 metres, while maintaining signal quality and data transmission reliability. The integrated sensor technology measures ambient temperature and relative humidity, with values transmitted in real time to the higher-level system.

Compatibility and Accessories

The sensor is specifically developed for use with compatible NetBotz appliances. It can be combined with additional accessories such as the temperature sensor AP9335T, the power supply AP9505i, the alarm light AP9324, or the mounting kit for door switches AP9513 to create a comprehensive environmental monitoring system. Integration requires no additional configuration, as the sensor is automatically recognised. The use of standard CAT5/6 cables enables easy system expansion.

Mounting and Installation

Mounting is tool-free using plastic mounting brackets that can be inserted into rack systems. The sensor is secured to the mounting plate, which is attached to the front trim panel or the rear of the device. The cable length of 3.9 metres allows for flexible placement, with extension via CAT5/6 cables up to 30 metres being possible. Mounting accessories such as cable ties, wire clamps, and the mounting plate ensure a secure and orderly installation. Installation follows the instructions included in the delivery, with the use of adhesive holders and cable ties recommended to properly secure the cables.

Operational Advantages

The sensor provides reliable and continuous monitoring of environmental conditions, enabling early detection of potential risks such as overheating or humidity damage. Automatic recognition by compatible NetBotz appliances reduces configuration effort and allows for quick integration into existing systems. Individual identification of the sensor with name and location simplifies data assignment and fault diagnosis. Tool-free mounting and the use of standard cables reduce installation effort and maintenance costs. Power supply via the network cable (PoE) eliminates the need for a separate power source, simplifying installation and increasing flexibility.
