Temperature Sensor Bachmann BN3000 with 2 m Cable and 2×RJ45 Connectors

The Bachmann BN3000 temperature sensor with 2 m cable and 2×RJ45 connectors is a compact wired probe designed for ambient and equipment temperature measurement where RJ45 connectivity is required. It provides stable temperature readings for integration with monitoring systems and building automation that accept RJ45 interfaces. The sensor is intended for fixed installation in professional and residential environments and offers a simple physical connection via two RJ45 plugs for routing and linking in existing cabling infrastructures.

Advantages

This temperature sensor delivers accurate ambient measurement in a compact form factor and a pre-attached 2 m cable that simplifies placement. Dual RJ45 connectors facilitate daisy-chaining or easy connection to networked monitoring modules and reduce the need for additional adapters. The wired design eliminates battery dependence and provides continuous measurement suitable for long-term monitoring and automation tasks.

Suitable for

• Environmental monitoring in server rooms, network cabinets, and equipment racks
• Building automation systems that use RJ45-connected sensors
• Residential climate monitoring where a wired RJ45 connection is preferred
• Integration with temperature logging and alarm systems

Key specifications

• Type: Ambient/equipment temperature sensor
• Cable length: 2 m
• Connectors: Two RJ45 plugs for direct RJ45 interfacing
• Mounting: Fixed placement; compact probe suitable for racks, walls, or equipment enclosures
• Power and data: Wired connection via RJ45 — no internal battery required

How to use

Position the sensor probe in the area where temperature measurement is required, avoiding direct exposure to heat sources or drafts for representative ambient readings. Plug the RJ45 connectors into the corresponding ports of the monitoring device, controller, or patch panel following the host equipment’s wiring scheme. Secure the cable along routing paths to prevent strain on connectors. After connection, verify detection and correct temperature reporting in the host system and adjust placement if readings appear influenced by nearby thermal disturbances.

Recommendations

For reliable measurements, install the sensor away from direct airflow of vents and heat-emitting components. Use shielded or properly terminated cabling in electrically noisy environments and follow the host device’s wiring and grounding guidelines when integrating via RJ45.
