Drawing

BL1243	-	1	2	XX	-	S
1		2	3	4		5

1) series:
     BL1243
2) insulator:
     1: one
3) Number of rows:
     2: two
4) number of pins in a row (2x40):
     01 ... 40
5) Type:
     S: straight

Pin headers, double row, corner of this series are made in the form of a comb 2x40 pins. Then they can be cut on a special device on factory at the request of the customer for any even number of contacts: 2, 4, 6... etc. The cost of cutting only slightly increases the price of a single contact, but the cut is almost perfect, without chipping at the ends, and the customer does not spend time on the work, which is easily done by the machine.
