The Weidmüller 1943670000, identified as the OMNIMATE BLZP 5.08HC/11/180, is an 11-pole terminal block plug designed for signal and power transmission applications in industrial control, automation, and electronic assembly. With a 5.08 mm pitch and straight (180°) conductor outlet, this plug suits free-hanging and in-line installations. It belongs to the OMNIMATE Signal - series BL/SL 5.08, offering high-current capabilities (“HC” designation), and features a clamping-yoke screw connection system, widely recognized for its robust reliability and ease of field wiring.

Mechanical Structure and Build of the Weidmüller 1943670000

The mechanical architecture of the Weidmüller 1943670000 emphasizes both durability and adaptability. The housing is constructed from polybutylene terephthalate (PBT), offering excellent mechanical stability and insulating properties. The plug’s dimensions are optimized for space-efficient PCB layouts: width 55.88 mm, depth 20.1 mm, and height 16 mm, with a single row of 11 positions. Each connector features retention latches on the non-wire side for secure mating and offers coding capability to prevent misconnection. The screw clamping yoke system, utilizing M2.5 screws, supports a tightening torque of 0.4–0.5 Nm, facilitating solid, vibration-resistant connections. Notably, the open clamping yoke design allows rapid wire insertion and enhanced protection against faulty wiring.

Electrical Characteristics of Weidmüller 1943670000

Electrical performance is central to the OMNIMATE BLZP 5.08HC/11/180, supporting both IEC and UL standards. The terminal block plug handles up to 23 A at 400 V (IEC) and 20 A at 300 V (UL). It is tested for surge voltages up to 4 kV and exhibits volume resistance of 5 mΩ, enabling stable, low-loss signal and power transmission. The rated cross-section per terminal is 4 mm² (IEC), and wire compatibility ranges from AWG 30 to AWG 12. These ratings make the 1943670000 ideal for demanding control and power applications where reliable connectivity and high current density are required.

Connection Methods and Wire Compatibility for Weidmüller 1943670000

The Weidmüller 1943670000 connector employs a field-proven screw-clamping yoke system, ensuring consistent performance across a range of wire configurations. The plug accepts solid and flexible conductors from 0.2 mm² to 4 mm², including ferruled wires compliant with DIN 46228 standards. Stripping lengths range from 6–7 mm, depending on wire type, and the plug accommodates both plastic-collar and wire-end ferrules. The 180° outlet direction simplifies routing in free-hanging setups, while the design integrates a plus/minus screw for versatile assembly. The plug supports up to 25 plugging cycles, with maximum plugging force per pole at 10 N, enabling repeated use in modular systems and maintenance-heavy environments.

Material Specifications and Environmental Standards of Weidmüller 1943670000

Material selection is critical for the longevity and safety of any connection system. The OMNIMATE BLZP 5.08HC/11/180 utilizes copper alloy contacts with 4–8 μm hot-dip tinning, ensuring low-contact resistance and excellent corrosion resistance. The orange PBT housing meets insulation group IIa and offers a CTI ≥200, with insulation strength ≥10 Ω. The plug is certified to UL94V-0 flammability rating and GWFI 960°C, providing fire safety assurance for equipment designers. Operating temperature spans from -50°C to +100°C, and storage conditions allow up to 80% relative humidity, supporting broad industrial deployment where environmental extremes can occur.

Safety Mechanisms and Regulatory Certifications of Weidmüller 1943670000

Safety and compliance underpin the OMNIMATE BLZP 5.08HC/11/180’s design, with protection against finger touch conforming to IEC and VDE standards. The device includes retention latches for secure mating, coding features to avoid misconnections, and measures that protect against faulty wire insertion. The product meets RoHS and REACH requirements, and carries UL and CSA approvals, including cURus and CB certifications. All clearance and creepage distances must be observed in accordance with the relevant application standards, as outlined in the documentation. The terminal block plug’s conformity with IPC-A-610 “Class 2” further assures production quality and durability for industrial installations.

Installation Procedures, Handling, and Engineering Uses of Weidmüller 1943670000

Engineers benefit from the plug’s straightforward installation and handling. The screw connection system is compatible with standard screwdriver blades (0.6 x 3.5, PH1, PZ1), easing field assembly. The wire entry angle and design simplify free-hanging or in-line connections, and the open yoke system improves both initial wiring and maintenance. Typical engineering scenarios include deployment in programmable logic controllers, industrial automation cabinets, power supplies, and modular signal distribution units—especially where high-current and repeated maintenance access are required. The provision for labelling space and integrated release latches facilitates circuit identification and modularity in complex control environments.

Alternative or Substitute Products for the Weidmüller 1943670000

In selecting alternatives for the Weidmüller 1943670000 terminal block plug, engineers might consider models within the OMNIMATE Signal BL/SL 5.08 series that offer similar position numbers, pitch, and connection technology. Equivalent plugs from other reputable brands (e.g., Phoenix Contact, Wago, or other terminal block specialists) should be evaluated for compatibility in pitch, rated current, voltage, clamping range, approval, and environmental performance. Key selection criteria include mechanical fit, electrical rating, and compliance certifications; ensure that equivalent models align with the required installation method (free hanging/in-line vs PCB mount), conductor outlet direction, and safety standards outlined above.
