DTV Series Connectors Explained

DTV Series Connectors Explained

Connector Family Guide

DTV Series connectors are sealed Deutsch connectors used for 18-way multi-circuit wiring applications. They provide a higher pin count option within the DT connector platform and are commonly used when multiple circuits need to be combined in a single sealed connector.

DTV connectors are not simply a higher-current alternative to DT or DTP. Their main advantage is the 18-way layout, which can help consolidate circuits in equipment wiring, industrial systems, off-highway vehicles, agricultural machinery and construction plant harnesses.

This guide explains what DTV Series connectors are, where they are used, how they compare with DT and DTP connectors, and what to check before ordering compatible housings, Size 16 contacts, wedgelocks and tools.

Quick Answer: What Are DTV Series Connectors?

DTV Series connectors are sealed 18-way Deutsch connectors used for multi-circuit harness applications. They typically use Size 16 contacts and are useful when several circuits need to be grouped into one sealed connector assembly.

What Are DTV Series Connectors?

DTV Series connectors are sealed multi-circuit Deutsch connectors used when a harness requires more positions than common smaller DT configurations. The DTV format is commonly associated with an 18-way layout and Size 16 contacts.

In practical terms, DTV connectors can help reduce the number of separate smaller connectors in a harness by consolidating several circuits into one sealed connector assembly. This makes them useful for equipment wiring, panel connections, machine harnesses and serviceable multi-circuit interfaces.

DTV vs DT vs DTP

DTV, DT and DTP connectors solve different selection problems. DTV is useful for higher cavity count wiring, DT is useful for general-purpose sealed wiring, and DTP is useful for higher-current circuits.

DTV comparison with DT and DTP connector families.
Connector family Typical role Best for Choose when... Shop
DT Series General-purpose sealed connector family. Lighting, relays, solenoids and standard harness branches. You need fewer circuits in a rectangular DT housing. Shop DT
DTV Series 18-way sealed multi-circuit connector family. Equipment harnesses with many circuits in one connector. You need an 18-way sealed connector using Size 16 contacts. Shop DTV
DTP Series Higher-current sealed connector family. Pumps, fans, motors and power accessories. You need larger contacts for higher-current circuits. Shop DTP

DTV Connector Housings

DTV connector housings should be chosen by part number, keying, color, contact configuration, mounting style and mating compatibility. Do not choose DTV parts by the 18-way count alone.

Contacts and Terminals

DTV Series connectors typically use Size 16 contacts. The correct contact must match the housing, contact side, wire gauge, current requirement and crimp tooling.

Choose DTV Connectors by Application

Choose DTV Series connectors when the application needs an 18-way sealed connector for multiple circuits. If the circuit count is lower, compare DT. If the current load is higher, compare DTP.

When DTV Series connectors are a good starting point.
Application need Is DTV a good fit? Selection note
18-way sealed connector Yes DTV is designed around higher cavity count applications.
Multi-circuit equipment harness Yes Useful when many circuits terminate in one connector interface.
Industrial control wiring Often Confirm cavity count, contact size and mounting style.
Simple 2-way or 4-way circuit Usually no Compare DT or DTM if fewer circuits are required.
Higher-current pump, fan or motor circuit Not automatically Compare DTP if the main requirement is higher current capacity.

Common DTV Series Selection Mistakes

Most DTV Series mistakes happen when users choose by circuit count alone and forget keying, contact configuration, accessories, wire gauge or mating compatibility.

Common DTV Series connector selection mistakes and better practice.
Mistake Why it causes problems Better practice
Assuming DTV is a high-current connector DTV is primarily a higher cavity count connector family, not a direct DTP replacement. Choose by both circuit count and current requirement.
Ignoring keying Incorrect keying can prevent mating or cause ordering mistakes. Match the exact part number and keying code.
Buying only the housing The housing may not include contacts, wedgelocks or seals. Confirm the full assembly before ordering.
Using the wrong contacts Wrong contacts may not crimp, insert or retain correctly. Confirm Size 16 contacts and wire gauge.
Using DTV when fewer circuits are needed An 18-way connector may add unnecessary size and complexity. Compare DT or DTM for smaller circuit counts.
