The 91921-32115LF is a Conan® 1.00mm mezzanine connector system engineered for secure, high-speed interconnection in harsh industrial environments. It features vertical and right-angle configurations with position counts ranging from 9 to 69, stack heights from 4.15mm to 7.0mm, and a maximum mated connector width of 5.59mm. The connector delivers high-speed performance with differential pair impedance of 100O ± 10, insertion loss less than 1.5dB up to 5GHz, and supports up to 5Gb/s data rates. Key mechanical characteristics include a mating force of 125g per contact maximum, unmating force of 25g per contact minimum, retention force of 44N minimum, and 30 mating cycle durability. The system incorporates an audible "click" sound during mating for enhanced security, polarization features to prevent mismating, and is RoHS compliant with lead-free construction. Applications include communications and networking equipment, electronic security systems, machine-to-machine (M2M) devices, medical diagnostics, and point-of-sale equipment.
