Pitch and Position Count — Board Fit and Harness Match
All 8 positions are loaded, so the header is ready for a full 8-circuit harness without blanking plugs.
Shrouding and Locking — Retention in Vibration
The shrouded-1-wall design provides keying to prevent mis-mating with non-MTA-100 receptacles, while the friction lock retains the mating connector under vibration and cable pull. This is a lower-engagement-force alternative to a detent lock; the mating half must have the corresponding lock ramp.
Contact Plating and Ratings — Signal-Duty Ceiling
Tin-plated mating contacts are cost-effective for one-time or occasional mating — they are not intended for frequent reconnection cycles where gold plating would be specified. Voltage rating is 250 VAC, covering most low-voltage signal and control circuits in industrial panels.
