This is a crimp-style housing — contacts are ordered separately.
The female socket contacts are crimp-terminated and must be purchased separately. Match the wire gauge and plating (tin vs gold) to the application duty — gold for high-cycle or corrosive environments, tin for cost-sensitive fixed installations.
The pitch is 0.138" (3.50 mm). That is the centre-to-centre spacing between adjacent contact positions.
The 174921-2 accepts female socket contacts with a crimp termination. The exact TE part number for the contact depends on wire gauge and plating — consult the Multi-Lock series application drawing for the correct terminal.
Yes, the 174921-2 is ROHS3 compliant.
The housing is moulded from Polybutylene Terephthalate (PBT), a common high-temperature thermoplastic for connector applications.
