It accepts tab-style crimp contacts (sold separately) and locks with a latch fastener that holds under vibration. The glass-filled thermoplastic body handles -55°C to 125°C, so it lives comfortably inside an engine bay or a hot cabinet. Four rows of cavities give this housing a compact layout for 12 circuits — the row count tells you the terminal arrangement is staggered, not a single line, which matters when you're routing wires into a tight bundle.
The listing note is clear: contacts are not included. This housing ships empty — you must source the matching Dynamic D-1000 tab crimp terminals separately. The termination is crimp, so you'll need the correct applicator tool or a hand crimper for the wire gauge the terminal accepts. RoHS compliance is confirmed, so no restriction-of-hazardous-substances issues for EU-bound assemblies.
