The latch lock fastening gives a positive audible click when mated with the matching header, holding the pair together without secondary hardware. This is the housing half of a wire-to-board or wire-to-wire interconnect system, typically used in internal harnesses for industrial controls, test equipment, and telecom gear where the 2.54mm pitch balances routing density with ease of hand assembly. The single-row layout keeps the housing narrow — useful when you are stacking several connectors across a board edge or routing a harness through a tight cable exit. ## Contacts Not Included — Order Separately A common trip point: the 1-104257-9 housing does not include contacts. The female socket terminals must be ordered as a separate line item — the TE AMPMODU MTE crimp socket (typically the 104257 series contact, e.g., 1-104257-0 or similar depending on wire gauge). Plan the BOM with both the housing and the per-position contacts. The crimp termination requires a hand or pneumatic tool with the correct AMPMODU MTE die set; the terminal locks into the housing with a positive retention ramp that gives a tactile click when fully seated. ## Mating Half and Locking This receptacle mates with the AMPMODU MTE pin header (through-hole or surface-mount, straight or right-angle) of the same pitch and position count — a 20-position, 0.100\" header. The latch lock on the housing engages with a corresponding slot on the header shroud. When the latch clicks, the pair is locked against vibration and accidental pull-off; you can still release it by lifting the latch tab. No secondary lock or screw is needed for most stationary applications.","metaTitle":"TE AMPMODU MTE 1-104257-9","metaDescription":"TE Connectivity AMPMODU MTE receptacle housing, 20 positions, 0.100\" (2.54mm) pitch, single row, latch lock, free-hanging, crimp termination.","metaKeywords":null},"attributes":{"series":"AMPMODU MTE","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors","Connector Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Note":"Contacts Not Included","Color":"Black","Pitch":"0.100\\\" (2.54mm)","Series":"AMPMODU MTE","Package":"Bulk","Features":"-","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Fastening Type":"Latch Lock","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Base Product Number":"104257","Contact Termination":"Crimp","Insulation Material":"Thermoplastic","Number of Positions":"20","Operating Temperature":"-65°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1700","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.17000","currency":"USD"},{"qty":10,"price":"$1.93200","currency":"USD"},{"qty":25,"price":"$1.92240","currency":"USD"},{"qty":50,"price":"$1.90280","currency":"USD"},{"qty":100,"price":"$1.74590","currency":"USD"},{"qty":250,"price":"$1.73604","currency":"USD"},{"qty":500,"price":"$1.57912","currency":"USD"},{"qty":1000,"price":"$1.41238","currency":"USD"},{"qty":2500,"price":"$1.30449","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Does the 1-104257-9 housing include contacts?","answer":"No — the 1-104257-9 ships as a housing only, with a clear 'Contacts Not Included' note.
