The TE Connectivity MATE-N-LOK 925451-1 is an 18-position plug housing designed for wire-to-wire power and signal interconnects. It carries a 5.20mm pitch across three rows with a 6.00mm row spacing, giving it a wider contact spread than the 2.50mm-pitch miniatures in the same family — useful when you need creepage for higher-voltage circuits or room for larger-gauge wires. The natural PA66 housing uses a latch lock for retention; no secondary connector position assurance (CPA) is built in, so the latch alone carries the vibration load. Mates with the corresponding MATE-N-LOK receptacle housing (same pitch and row count) to complete the harness splice.
The Contacts Are the Real Spec — This Housing Ships Empty
The listing note reads Contacts Not Included, and that is the single most important procurement detail on this page. The 5.20mm pitch and 6.00mm row spacing accept the standard MATE-N-LOK contact family; the exact terminal part number depends on your wire gauge and plating preference (tin for cost-sensitive signal duty, gold for corrosive environments or frequent mating cycles). Without the terminal order code on the BOM line, the housing is just a plastic placeholder.
Temperature Range and Material for the Environment
The natural colour indicates unfilled nylon — no glass reinforcement, so the latch has some flex but the housing is more susceptible to creep under sustained high-temperature load near the 105°C ceiling. For applications requiring glow-wire compliance or higher mechanical stiffness, the glass-filled sibling 1-1644055-3 (6.35mm pitch, 2-row) is a different form factor but shares the MATE-N-LOK terminal family.
