Deutsch DT04-4P-E005 / DT06-4S-E005 4-Pin 1.6mm Male & Female Connector – Engineering Vehicle

Direct-fit replacement for Deutsch OEM part numbers DT04-4P-E005 (male plug) and DT06-4S-E005 (female socket), a 4-pin 1.6mm pitch connector pair from the Deutsch DT series with E005 keying. The E005 keying variant is specifically used in engineering, construction, and agricultural vehicle harnesses to prevent mis-mating with standard DT connectors in multi-connector harness assemblies.

• Construction vehicle ECU and sensor harness connections
• Mining equipment control harnesses
• Aftermarket engine management harnesses for off-highway vehicles

E005 Keying – Why It Matters

In complex multi-connector harness assemblies (such as excavator main harnesses with 20+ connectors), keying prevents technicians from connecting the wrong circuits during assembly or service. The E005 keying physically prevents the DT04-4P-E005 from mating with a standard DT06-4S or any other keying variant – even if the pin count is identical. This is critical in high-stakes applications where mis-mating could damage expensive ECUs or cause safety-critical circuit failures.

Frequently Asked Questions

Q: Will DT04-4P-E005 mate with a standard DT06-4S (no keying)?
A: No. The E005 keying tab physically prevents mating with standard DT06-4S connectors. You must use the matching DT06-4S-E005 female socket.

Q: What terminals are used in DT04-4P-E005 / DT06-4S-E005?
A: Size 16 contacts – 0460-202-16141 (pin/male terminal) for DT04-4P-E005 and 0462-201-16141 (socket/female terminal) for DT06-4S-E005. These accept 16–18 AWG (0.5–1.0 mm²) wire. Use the Deutsch HDT-48-00 crimp tool or equivalent.

Q: What is the wedgelock part number for DT06-4S-E005?
A: The wedgelock for all DT06-4S variants (including E005) is W4S. It must be fully seated after all terminals are inserted.

Q: Can I use DT04-4P-E005 in a sealed (waterproof) application?
A: The standard DT04-4P-E005 is unsealed. For waterproof applications, use individual wire seals (114017) inserted into each cavity before terminal installation, converting it to a sealed configuration.
