Frequently Asked Questions
What contact count and pitch does the TFM-138-22-S-D-A-P-TR provide?
The TFM-138-22-S-D-A-P-TR is a dual-row terminal strip with 38 positions per row at a 0.050-inch (1.27 mm) pitch, giving a total of 76 contacts. This configuration supports high-density signal and power interconnect on boards where minimizing connector footprint to under 50 mm in length is required.
Why is the Tiger Eye contact technology in TFM-138-22-S-D-A-P-TR preferred for aerospace and defense applications?
Tiger Eye contacts maintain stable electrical performance with contact resistance typically below 20 milliohms even after thousands of mating and unmating cycles. This durability is critical in aerospace and defense systems where field replacement and frequent connector cycling must not degrade signal integrity across 76 contacts in a 1.27 mm pitch format.
When would a designer choose the TFM-138-22-S-D-A-P-TR over a 0.100-inch pitch dual-row connector of similar contact count?
The 0.050-inch (1.27 mm) pitch of the TFM-138-22-S-D-A-P-TR occupies roughly half the board length of an equivalent 0.100-inch pitch connector for the same 76-contact count, freeing board space in compact mezzanine and stacked PCB designs. It is the preferred choice when PCB area is constrained to less than 50 mm for the connector zone and high cycle life above 500 matings is required.
