3M 2500 User Manual

3M™ 4-Wall Header

.100″ × .100″ Low Profile, SMT Straight, PTH Straight and Right Angle 2500 Series

• Low profile, space saving design

• Center slot polarization prevents mis-insertions
and reduces insertion time

• Dual slot polarization means broader compatibility
with competitive polarization designs

• Optional retainer clip for locking sockets in place
and increasing connection reliability in vibration­prone environments

• High temperature insulator suitable for “no lead”
soldering operations

• Thru hole version suitable for "paste in hole" reflow
soldering techniques

• Exposed solder tails (on right angle version)
provide ease of cleaning and reduced repair costs

• RoHS* compliant

• Straight surface mount version available
