What Are PSA Cables?

The medical industry, in the field of cardiology, uses devices called pacing system analyzers or PSAs. This is not to be confused with the prostate specific antigen (PSA), which is a blood test to detect colon cancer. These pacing system analyzers monitor heart activity inside the human body. Cables are used to connect the pacing system analyzer to the monitoring implant such as a pacemaker. These connecting cables are called PSA cables.

  1. Description

    • There are different types and configurations of PSA cables. Typically there are two color-coded, single-conductor cables. These cables are insulated along the length of the conductor and the connectors are insulated typically using a shroud.

    Connectors

    • Alligator clips are used on some PSA cables. These alligator clips are insulated with a shroud. These are high-quality precision machined alligator clips.

    HyperTronic Connectors

    • HyperTronic PSA cables use a quick-release, push-on connector that has two conductors. This connector is shielded to block electromagnetic interference (EMI) and radio frequency interference (RFI). Shielding bandwidth extends to 3 GHz and will attenuate EMI and RFI down by 50 dB. These connectors are designed for digital signals with high data transfer rates.

    Cable and Connector Characteristics

    • Because of the critical nature of the job that these PSA cables and connectors perform, they are manufactured to perform with the highest degree of reliability under extreme conditions. For example, the HyperTronic connector has a minimum life of 15,000 mating cycles. All PSA cables and connectors are delivered sterile, ready for the medical environment.
