DESCRIPTION
The pin strips 121-M-151 und 121-M-251, as two-tier version with a pitch of 5,08 mm are available in 4- to 24-pole design. The ..-M-151 version is a pin strip without side walls and can be mounted side-by-side without pole loss. The ..-M-251 version is a pin strip with closed side walls. For both versions, the plug direction for mating plug connectors is parallel to the PCB. For each pole, the pin strips have one trapezoidal coding slot in which the coding elements 120-K can be inserted.
