Why Choose the Partex BM50/VR Blue Male Tab Terminal?
The Partex BM50/VR is a professional blue pre-insulated male tab crimp terminal designed for connecting stranded copper conductors to compatible female push-on connectors. Featuring a 4.8 mm wide × 0.8 mm thick male tab, this connector provides a convenient, detachable electrical connection for industrial control panels, machinery wiring, electrical equipment and cable assemblies.
Designed for conductors measuring 1.5–2.5 mm² (16–14 AWG), the BM50/VR combines a C2680 brass terminal body with high-quality blue PVC insulation. Its pre-insulated crimp barrel allows installers to create a secure electrical termination using an appropriately sized crimping tool, without requiring soldering.
The VR designation indicates increased vibration resistance. The terminal incorporates an additional copper support sleeve within the insulated crimp section, helping reinforce the conductor termination in applications where equipment movement and vibration may be present.
With an overall length of 22.5 mm, a 4.9 mm insulation diameter and an 11 mm barrel length, the BM50/VR offers a compact connection format. Supplied in a pack of 100 terminals, it is well suited to electrical contractors, control panel manufacturers, maintenance teams and OEM cable assembly operations.

Vibration-Resistant Male Tab Connections for Industrial Wiring
The Partex BM50/VR is designed to create a crimped electrical termination that can be connected to a compatible female push-on connector. The flat 4.8 × 0.8 mm male tab provides the mating contact surface, while the insulated barrel secures the stranded copper conductor.
The terminal's VR construction incorporates additional copper reinforcement within the crimp section. This design helps support the conductor termination where machinery vibration or movement may occur. It does not eliminate the need for suitable cable restraint, strain relief or secure equipment mounting.
The C2680 brass contact provides the conductive male connection surface. When correctly paired with a compatible female terminal, the connection allows equipment wiring to be disconnected and reconnected for maintenance or component replacement. The mating female connector must be suitable for both the 4.8 mm tab width and 0.8 mm tab thickness.
The blue PVC insulation identifies the 1.5–2.5 mm² conductor range. Using the correct conductor size and matching crimping die is essential because an undersized conductor or incorrect crimp profile can compromise the mechanical strength and electrical performance of the termination.
To install the terminal, strip the conductor to the appropriate length without damaging the strands. Insert the conductor fully into the crimp barrel, position the terminal in the correct blue insulated crimping die and complete the crimp according to the tool manufacturer's instructions. Inspect the termination and check conductor retention before connecting it to the female terminal.
The BM50/VR is a male tab terminal rather than a complete connector pair. A suitable female push-on terminal must be selected separately. For example, the Partex BF50/08/VR is a blue female push-on terminal designed to accept a 4.8 mm wide, 0.8 mm thick male tab.
