NTSEAL Pin Housings for Male Terminals.

Q: What is an NTSEAL housing for male terminals, and how does it differ from the plug version?

A: In the NTSEAL connector family, the housing for male terminals is the pin housing sometimes called the receptacle in the catalog. It mates with the plug that carries socket contacts. Pin housings are offered with or without a flange for panel mount and are color coded and keyed to avoid cross mating. See the position tables and coding examples on pages 3 through 8 of the datasheet.

Q: What ingress protection do these housings achieve in the field?

A: When used with the matching backshell, NTSEAL achieves IP67, IP68, and IP6K9K for dust, immersion, and high pressure spray. This rating supports under hood, chassis, and washdown environments..

Q: What temperature and vibration performance should I design for?

A: Operating temperature is 40° to 125°C (-40° – 257°F). The series is described as suitable for engine level vibrations, which is why it is used around engines, e motors, transmissions, and frames.

Q: What system voltage and contact current does the housing support?

A: NTSEAL is used in 12 volt and 24 volt vehicle systems. Contact current depends on contact size at 125°C: about 7.5 A for size 20, 13 A for size 16, and 25 A for size 12.

Q: Which DEUTSCH contacts fit these male terminal housings and what wire sizes can I use?

A: NTSEAL uses the DEUTSCH common contact system in sizes 20, 16, and 12. Typical wire ranges are 0.5 to 1.5 mm² for size 20, 1.0 to 2.5 mm² for size 16, and 2.0 to 6.0 mm² for size 12.

Q: What position counts are available for male terminal housings?

A: The family covers 18, 20, 26, 36, 38, and 48 positions. Contact mixes vary by shell size, letting you combine power and signal in one connector. See pages 3 through 8 of the datasheet for pin housing options by size.

Q: Do the housings include safeguards for contact retention and latch security?

A: Yes. TPA is a terminal position assurance feature that helps confirm each crimped contact is fully seated. CPA is a connector position assurance feature that helps keep the latch in the locked state after mating. Both are integrated into the system. See the feature list on page 1 of the datasheet.

Q: Is there an assisted mating option for higher pin counts?

A: The 26, 36, 38, and 48 position connectors include an integrated locking lever to support mating and speed assembly.

Q: What panel mount choices exist for pin housings, and how do I pick the right ring?

A: Pin housings are available with a flange for panel mount or without a flange for in line use. Mounting rings are color coded for common panel thickness values, for example 1.5, 3.0, 3.5, and 4.0 mm. See the mounting ring tables near each shell size in the datasheet.

Q: Which backshells and accessories pair with male terminal housings?

A: Backshells are offered in one hundred eighty degree and ninety degree outlets. The ninety degree can rotate a full three hundred sixty degrees when used with the 180° base. Accessories include sealing plugs, sealed caps, and mounting clips.

Q: What coding options prevent mis mating during service?

A: Four coding options labeled A, B, C, and D are offered. They are also color coded (black, grey, green, blue) to help technicians match pairs on the line and in the field.

Q: What materials are used for the housing and lock features?

A: The housing, CPA, and TPA are made of PBT. This choice balances strength, stability, and chemical resistance for transportation environments.

Q: Where do I find crimping and assembly guidance or test details?

A: Use the Application Specification 114-32209 for termination and assembly practices and the Product Specification 108-101662 for performance details.

Q: How do I decide which contact mix to use for my harness area, for example engine bay versus battery and charging?

A: Match the current and wire size first, then the position count and IP rating needed for that area. For example, select size 12 cavities when you need contact currents around 25A at 125°C and plan for IP6K9K where high pressure spray occurs.
