Description
Bently 21747‑040‑00
- Key Features: 50‑ohm high‑frequency coaxial structure; PTFE insulation material; double‑ended microdot male‑female connectors; non‑armored lightweight design; low‑signal‑loss transmission; good anti‑interference shielding performance.
- Technical Specifications & Performance Parameters
- Total cable length: 4.0 m
- Cable impedance: 50 Ω nominal
- Operating temperature range: ‑40 ℃ ~ +85 ℃
- Storage temperature: ‑55 ℃ ~ +125 ℃
- Weight: 0.59 kg
- Material Composition: High‑purity copper inner conductor; PTFE dielectric insulation layer; copper‑braided shielding layer; outer‑jacket high‑temperature‑resistant polymer; metal microdot male‑female connector assemblies at both ends.
- Structural Features: Flexible circular coaxial‑cable body; microdot female‑connector at probe‑side terminal; microdot male‑connector at proximitor‑side terminal; compact connector shell structure; continuous shielding braid runs through full cable length.
- Working Principle: It serves as high‑frequency signal transmission medium between proximity probe and proximitor unit. It transmits proximitor high‑frequency excitation signal toward probe, and returns probe coil impedance‑variation signal back to proximitor unit, maintaining complete electrical characteristics of whole transducer loop.
- Application Scenarios: Signal‑transmission extension for 7200‑series proximity probes; field‑installation position far away from monitoring cabinet; spare‑part replacement for aged original extension‑cables.
- Installation Requirements: Connect female microdot end to probe integral‑cable connector; connect male microdot end to proximitor unit; tighten each microdot‑connector locking ring completely; keep minimum bending radius of coaxial‑cable; lay extension‑cable separately from high‑voltage power‑cables; implement single‑end grounding for cable shielding braid.
- Usage Notes: Never cut or splice extension‑cable at any intermediate‑position; avoid sharp‑angle small‑radius bending; keep microdot‑connector contact‑pins free of dust, water and grease; total sum length of probe integral‑cable plus extension‑cable must comply with proximitor factory‑calibration requirement.
