7. Frequently Asked Questions
What data rate does the HSI series support?
The HSI series supports data rates exceeding 3.125 Gbps, making it suitable for high-speed digital signal transmission in demanding environments.
What board-to-board heights are available?
Ten standard heights are available: 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15 mm. The height is specified by a letter code in the part number (J through I).
How many contact positions can I get?
The series offers 13 standard contact counts: 20, 30, 40, 50, 60, 64, 70, 80, 84, 90, 100, 110, and 120 positions.
What is the difference between TJ and ZK connector types?
TJ designates a plug connector with pin contacts, while ZK designates a receptacle connector with socket contacts. They are a fixed mating pair.
Are locking components available?
By default, the connector has no locking components. A P-type locking component is available as an option. For parallel board applications, external support pillars and locking devices are recommended.
