31-Pin Automotive Wire Harness Plug – HDP24-24-31PE-L017, Heavy-Duty Plastic Connector

HDP24-24-31PE-L017 is a 31-pin heavy-duty automotive wire harness plug from the Deutsch / TE Connectivity HDP20 series. This is the plug (male housing) variant — compare with HDP26-24-31PE-L017 which is the receptacle (female housing). The HDP20 series is the standard for high pin count sealed connections in commercial trucks, agricultural equipment, and industrial vehicles. The 31-pin configuration supports complex multi-circuit harness connections in a single IP67-rated connector.

HDP24 vs HDP26 — Plug vs Receptacle

• HDP24-24-31PE-L017 (this product): Plug housing. Accepts male pin contacts (0460-202-20141). The plug is the cable-mount half that connects to the panel-mount or cable-mount receptacle.
• HDP26-24-31PE-L017: Receptacle housing. Accepts female socket contacts (0462-201-20141). The receptacle is typically the panel-mount or equipment-side connector.
• Mating pair: HDP24-24-31PE-L017 (plug) + HDP26-24-31PE-L017 (receptacle) form a complete 31-pin sealed connector assembly.

Frequently Asked Questions

What contacts are compatible with HDP24-24-31PE-L017?

The HDP24 plug housing accepts size 20 male pin contacts: Deutsch part number 0460-202-20141. These are different from DT series size 16 contacts — do not mix contact sizes between series. The size 20 contacts require the Deutsch HDT-48-00 crimp tool with size 20 dies.

How does the HDP20 series locking mechanism work?

The HDP20 series uses a lever-actuated locking mechanism: a lever on the plug housing engages a ramp on the receptacle housing, drawing the two halves together and locking them in the mated position. This provides a positive mating force that ensures all 31 contacts are fully engaged simultaneously. To unmate: depress the lever release and pull the plug straight out. Do not pull the cable — always grip the plug housing when mating and unmating.

What is the current rating for HDP20 size 20 contacts?

Size 20 contacts are rated at 7.5A per contact. For a 31-pin connector with all contacts loaded at 7.5A: total current = 232.5A. In practice, not all contacts carry maximum current simultaneously — the connector’s total current capacity is limited by the housing’s thermal dissipation. For circuits requiring more than 7.5A per contact, use DT series size 16 contacts (13A) or DTP series size 12 contacts (25A).

Typical Applications

• Commercial trucks: Cab-to-chassis main harness plug connections
• Agricultural equipment: Tractor-to-implement and ECM harness plug connections
• Construction equipment: Multi-circuit control harness plug connections
• Industrial vehicles: Forklift and material handling equipment harness connections
