24-Position MR Series Receptacle Housing — Panel-Mount, 4.20 mm Pitch
The housing accepts male pin crimp contacts, terminated by a standard crimp tool, and snaps into a panel cutout for a fixed installation. That temperature envelope covers most equipment inside a climate-controlled cabinet or passenger compartment — not for underhood or continuous high-heat zones. The housing is available in black or red, which can be used for keying by circuit function in multi-connector assemblies.
Mating Header and Contact Selection
Because the housing is a receptacle, the mating header carries the male pins; the housing itself accepts the male pin crimp terminals that terminate the wires. Crimp contacts for this housing are ordered separately — the TE part numbers for the male pin contacts vary by wire gauge and plating finish. Standard practice is to select a contact rated for the circuit current and wire size, then crimp with the manufacturer-recommended tooling. The housing's 4.20 mm pitch and 4-row layout give enough clearance for 18-22 AWG wire in most harness builds.
Panel Mounting and Installation
Mounting is panel-mount snap-in — the housing presses into a rectangular cutout and locks with integral retaining features. No additional hardware is needed. This is a common arrangement for bulkhead pass-through or junction box entry points where the connector stays fixed and the mating half connects from the other side. The snap-in retention holds the housing during wire insertion and mating, but the latch lock on the mating face carries the primary retention load once mated. The 4-row, 24-position layout means the panel cutout must accommodate the full width of the housing. Verify the cutout dimensions from the product drawing before committing the panel design — the snap-in ears and latch lock geometry add to the overall envelope beyond the contact grid.
