Whirlwind Mass Multipin Connectors High Density Multipin Audio Connector
The MASS connector series is Whirlwind's high pin-count multipin range, built for the cable runs where 39 pins are nowhere near enough. Crimp type pins and sockets are used throughout, which is faster to build and easier to repair in the field than solder at these pin counts.
Three sizes are listed here. MicroMASS is the 48 pin, MASS is 122 or 176 pin, and each is available as a chassis mount or an inline connector. W3CRP is the 122 pin chassis, W3IRP the 122 pin inline, W4CRP and W4IRP the 176 pin chassis and inline, W5CRP and W5IRP the 48 pin MicroMASS chassis and inline. The M48, M122 and M176 part numbers are the individual components in each shell size.
