FAQ

Q1: What is the purpose of model 129957-085-310-085?
A1: This cable is used to extend the connection between an 8 mm proximity probe in the 3300 XL system and its corresponding Proximitor amplifier, maintaining signal integrity over longer runs.

Q2: What cable length does it offer?
A2: The standard length for this variant is approximately 8.5 meters.

Q3: What is the impedance specification?
A3: The cable has a characteristic impedance of 50 Ω ±2 Ω to match the 3300 XL system requirements.

Q4: What temperature range can this cable operate in?
A4: It is rated for operation from –51 °C up to +177 °C, suitable for demanding industrial environments.

Q5: What is the tolerable signal attenuation?
A5: Signal attenuation is less than 0.28 dB per meter at 10 MHz, preserving signal accuracy across the extension length.

Q6: What is the voltage withstand capability of the cable?
A6: It can withstand 2 kV AC between shield and conductor, ensuring robustness in harsh conditions.

Q7: How does this part integrate into the system?
A7: It is specifically matched to the 8 mm probe of the 3300 XL system, serving as the intermediate extension cable to the Proximitor amplifier module.

Q8: What should be checked when replacing this cable?
A8: You should confirm the correct length (8.5 m for this variant), impedance (50 Ω), compatibility with 8 mm probe system, and ensure the cable end-connectors match your Proximitor amplifier interface.
