Real World Applications
AMPSEAL 16 Connector Housings
Engine Compartment and Powertrain Zones
AMPSEAL 16 connector housings are used in engine bay and powertrain areas where vibration, heat, and fluid exposure are common. High-temperature variants rated up to 150°C support routing near exhaust manifolds, turbochargers, and aftertreatment systems.
Aftertreatment Modules (DOC – Diesel Oxidation Catalyst, DPF – Diesel Particulate Filter, SCR – Selective Catalytic Reduction)
These sealed connector housings support electrical interfaces for diesel oxidation catalyst, diesel particulate filter, and selective catalytic reduction modules where elevated temperature and road spray are present.
Chassis Harness Breakpoints
AMPSEAL 16 plug and cap connector housings are commonly applied at frame rail junctions and underbody harness splits where sealing against dirt, moisture, and debris is critical to long-term signal stability.
Brake and Stability Control Systems
Used in ABS and electronic stability control modules, these connector housings provide multi-pin sealed interfaces in zones exposed to shock, vibration, and environmental contamination.
Construction and Agricultural Equipment
In off-highway machinery, AMPSEAL 16 sealed connector housings help support reliable connections in hydraulic systems, actuators, sensors, and lighting circuits exposed to dust, mud, and frequent washdown.
Auxiliary and Body Electronics
The AMPSEAL 16 connector system supports lighting, telematics, and auxiliary modules where secure mating, keying, and sealing performance help reduce service errors and intermittent faults.

Seal selection note (helps avoid rework):
- Standard seal (N): insulation OD ~2.18–3.67 mm (0.086–0.144 in)
- Reduced seal (E): insulation OD ~1.30–2.54 mm (0.051–0.100 in)
Quick Selection Guide
AMPSEAL 16 Connector Series
| Decision | When to choose it | What to check |
|---|---|---|
| Standard temperature housing | Use for most harness zones that stay within -40°C to 125°C | Expected ambient at the connector, proximity to engine and exhaust heat |
| High temperature housing | Use when the connector can see higher heat, up to -40°C to 150°C, such as on-engine, aftertreatment, and powertrain zones | Target zone temperature, heat soak, and nearby aftertreatment equipment |
| Standard wire seal option | Use when wire insulation outside diameter fits the standard seal range | Measure insulation OD and match to the published wire seal range |
| Reduced wire seal option | Use when wire insulation outside diameter is smaller and needs a reduced seal | Measure insulation OD and match to the reduced seal range |
| Keying A, B, C, or D | Use when you have multiple connectors of the same cavity count in one harness and want to reduce mismating risk | Define harness build strategy and assign key codes per mating pair |
| Add backshells | Use when you need added strain relief, cleaner routing, or added rear protection in exposed harness locations | Harness bend radius, pull forces, abrasion risk, and routing constraints |
| Fill unused cavities with sealing plugs | Use whenever you have unused positions and still need environmental sealing | Confirm cavity count versus loaded circuits before final assembly |
Frequently Asked Questions
Q: What are AMPSEAL 16 connector housings used for?
A: AMPSEAL 16 connector housings are used to build sealed wire-to-wire and wire-to-device connections in harsh industrial and commercial transportation environments. They accept size 16 contacts and support 2 to 12 circuits per connector.
Q: What is the difference between a plug housing and a cap housing?
A: Plug and cap housings are the two mating halves of the AMPSEAL 16 connector interface. One side typically contains pin contacts and the other contains socket contacts. Selection depends on harness design and mating orientation requirements.
Q: What does CPA mean on an AMPSEAL 16 connector?
A: CPA stands for Connector Position Assurance. It is a secondary locking feature that engages after mating and helps reduce the risk of accidental unmating in high-vibration applications.
Q: What does TPA mean?
A: TPA stands for Terminal Position Assurance. It helps confirm that each contact is fully seated inside the housing, which can reduce the chance of a backed-out terminal during assembly or service.
Q: What temperature range do AMPSEAL 16 connector housings support?
A: Standard versions operate from −40°C to +125°C. High-temperature variants operate up to +150°C and are suited for hotter zones such as engine compartments and aftertreatment systems.
Q: What ingress protection rating is supported?
A: AMPSEAL 16 connector housings are designed to support IP67 environmental sealing. When used with appropriate rear protection and accessories, higher ingress protection performance can be supported depending on configuration.
Q: What wire sizes are supported?
A: The system supports 14–20 AWG conductors using HDSF size 16 contacts. Seal selection depends on wire insulation outside diameter.
Q: How do I select the correct housing configuration?
A: Selection typically involves confirming:
- Position count (2, 3, 4, 6, 8, or 12)
- Temperature grade (standard or high temperature)
- Keying code (A, B, C, or D)
- Wire seal type (standard or reduced diameter)
- Plug or cap orientation
Q: Can I request a sample?
A: Yes. Select the required AMPSEAL 16 connector housing part number and open the individual product page. From there, use the “Get Free Samples” option to begin the request process.
