Target Applications
Joins a male 3.5 mm cable to a male 1.85 mm cable or component port.
Maintains a defined cross-series transition when both measurement interfaces are male-ended.
Bridges male fixture hardware without adding a cable assembly between connector families.
Supports laboratory setups that require a confirmed mating life of at least 500 cycles.
