The housing accepts the standard SL-156 crimp contact (TE part number 1-770849-0 or similar), which terminates 18-24 AWG wire. No soldering, no special tooling beyond a hand crimper. ## Locking Ramp and Polarizing Key Keep the Mate Right Two features make this housing field-friendly. The locking ramp gives an audible click when the housing fully mates with the header — you feel it seat. That's your confirmation the connection is locked, not just pushed together. The polarizing key (a molded rib in the housing wall) means the plug only goes on one way. On a harness with a dozen SL-156 connectors, the keying stops a mis-mate before it happens.","metaTitle":"TE SL-156 Receptacle Housing 2-770849-0, 20 Pos, 3.96mm","metaDescription":"2-770849-0 TE SL-156 receptacle housing, 20 positions, 0.156\" (3.96mm) pitch, natural nylon, locking ramp, polarizing key.
