Weidmüller 1003160000 HDC HQ 4/2 FC Female Insert Overview
The Weidmüller 1003160000 HDC HQ 4/2 FC is a compact heavy-duty connector insert built for applications that need both robust power handling and practical signal integration in a space-efficient format. In many industrial installations, connector real estate is limited, yet the application still requires a dependable interface for mixed loads. That is exactly why hybrid inserts such as the Weidmüller HDC HQ 4/2 FC remain highly relevant.
This insert is specified as a female HDC insert with a crimp connection, HQ installation size, and a mixed pole arrangement described as 4/2 (+PE). The product is associated with 690 V / 40 A on the main power side, while the technical documentation also identifies a 40/10 A current profile and 690 / 250 V rated voltage context for the hybrid arrangement. That makes it suitable for installations where both power and lower-level auxiliary circuits need to be handled inside one connector concept.
Understanding the Weidmüller HDC HQ 4/2 FC Design
The phrase Weidmüller 1003160000 HDC HQ 4/2 FC female insert tells you a great deal about the product. “FC” denotes the female version, while “4/2” indicates a hybrid pole structure that combines power and additional contacts in a compact insert body. This is valuable in industrial systems where separate connectors would increase complexity, require more mounting space, and add extra interface points.
The HQ form factor is designed to deliver a high functional density in a smaller installation footprint. That makes the Weidmüller HDC HQ 4/2 FC insert attractive for machine modules, compact drives, handling equipment, and automation assemblies where panel space and connector volume must be used efficiently.
Technical Characteristics That Matter
The Weidmüller 1003160000 is a female insert with 6 positions in practical distributor references and a hybrid specification of 4/2 (+PE) in technical documentation. It uses a crimp connection, which remains one of the most trusted connection technologies in industrial connector engineering because it supports stable, repeatable contact termination when properly processed.
From an electrical standpoint, the insert is identified with 690 V and 40 A in the general version line, while the hybrid documentation details 40/10 A rated current and 690 / 250 V rated voltage. UL/CSA-related documentation also references 600 V AC/DC. This makes the insert suitable for demanding industrial tasks that combine motor or power-related circuits with lower-rated auxiliary functions.
The product also supports a crimp-based wire connection structure, and the supplied insert does not include the crimp contacts themselves. That is standard for many professional heavy-duty connector systems and allows the contact selection to be adapted to conductor size and application requirements.
Why Engineers Choose Hybrid HQ Inserts
A hybrid insert reduces connector count, simplifies cable management, and can improve serviceability. Instead of routing separate connectors for power and control, a single properly designed insert can create a cleaner and more maintainable interface. The Weidmüller 1003160000 HDC HQ 4/2 FC connector insert is a strong example of that approach.
It is particularly useful in machine building, modular production equipment, decentralized automation nodes, and transport-related equipment where a compact but structured interface is preferred. In these environments, reducing installation size without sacrificing robustness is often a major design target.
Practical Selection Notes
Anyone selecting the Weidmüller HDC HQ 4/2 FC female insert should verify mating compatibility with the matching male insert, suitable HQ housing, and the correct crimp contact system. Because the insert is only one element within the full connector assembly, overall performance depends on correct pairing across housing, insert, contact, and accessory levels.

FAQ
What is the Weidmüller 1003160000 HDC HQ 4/2 FC?
It is a female heavy-duty connector insert in the HQ series, designed with a hybrid 4/2 (+PE) pole structure and crimp connection.
What are the main electrical ratings of the Weidmüller HDC HQ 4/2 FC?
The product is associated with 690 V and 40 A in the main version description, with hybrid documentation also showing 40/10 A and 690 / 250 V depending on contact grouping.
Is this a male or female insert?
The Weidmüller 1003160000 is the female version. The matching male variant is the corresponding MC version within the same family.
Does the insert include crimp contacts?
No. The insert is supplied without crimp contacts. Contact elements are selected separately according to conductor size and application needs.
Why would someone choose a 4/2 hybrid insert instead of separate connectors?
A hybrid insert can save space, simplify wiring architecture, and reduce the number of separate interfaces in a machine or industrial system.
Where is the Weidmüller 1003160000 commonly used?
Typical applications include machine building, automation modules, compact power-and-control interfaces, industrial transport equipment, and installations where connector density matters.
