JST VHR-4N Male Female Connector Wire Harness 3.96mm Terminal Cable

This extension wire harness adopts original JST VH series VHR plastic housings and matched crimp terminals, a standard 3.96mm wide-pitch wire-to-wire & wire-to-board connector available in 2Pin, 3Pin, 4Pin (VHR-4N) and 9Pin versions. It supports medium-current power supply and mixed signal transmission, widely applied to industrial control equipment, refrigeration compressors, motor drivers, switching power supplies and internal extension wiring of household appliances. Matching male and female housings can be made into ready-made extension jumpers. The flame-retardant shell features wide temperature resistance, each pin supports 10A continuous current. All harnesses are finished with terminal crimping and wire reinforcement. Customizable wire length, wire color and terminal configuration are available. All raw materials comply with RoHS environmental standards.

Specifications

Advantages

• 3.96mm Wide Safe Pitch

  Large pin clearance provides sufficient creepage distance. Compared with small-pitch connectors of 1.25mm / 2.54mm, it effectively prevents circuit short circuits in high-humidity and high-temperature control cabinets, ideal for medium-power loads such as motors and compressors.

• 10A High Current Carrying Capacity

  Thick tin-plated large terminals support heavy loads including refrigeration compressors, industrial cooling fans and heating modules, which cannot be replaced by miniature fine-pitch signal connectors.

• Complete Male & Female Extension Solution

  Ready-made extension jumpers with male plug on one end and female housing on the other are available. No manual tape-wrapped joints are required for on-site wiring, realizing standardized assembly and eliminating hidden dangers of short circuits caused by aging insulation tape.

• Dual Anti-Loosening Protection

  External shell snap lock + internal terminal locking tab offer double fixation. No terminal retreat or loose plug-off power failure occurs under long-term equipment vibration.

• Anti-Reverse Plug Positioning Structure

  Asymmetric positioning ribs on male and female shells physically block reverse insertion, avoiding burnout of main control boards and motor drive chips caused by reversed power supply.

• Wide Temperature Weather Resistance for Multiple Scenarios

  Nylon housing resists cracking at low temperature and deformation at high temperature. It fits low-temperature cavities of refrigerators & freezers as well as internal wiring of high-temperature equipment such as water heaters and ovens.

FAQ

Q1: What does VHR-4N stand for?

A1: VHR is the code for female housing of JST VH 3.96mm series; 4 means 4 pins, N represents female receptacle, which needs to mate with corresponding male plugs of VH series.

Q2: Can this harness be used for high-power circuits of compressors and motors?

A2: Yes. Each pin stably carries 10A continuous current. The wide-pitch housing and thick tin-plated terminals fully meet the power transmission demands of low-voltage small motors and refrigerator compressors.

Q3: What is the difference between 3.96mm VHR and 4.2mm Molex Mini-Fit?

A3: VHR adopts tin-plated terminals with cost advantages, mainly for medium-power wiring of household appliances; Mini-Fit uses gold-plated terminals with stronger anti-interference performance. They belong to different brand series and cannot cross-mate.

Q4: Can we customize finished extension cables with male plug on one end and female housing on the other?

A4: Yes. We can produce full-length male-female extension jumpers according to equipment wiring distance requirements.

Q5: Can this connector be applied to low-temperature freezer environments?

A5: The Nylon 66 housing works stably from -40℃ to +105℃ without cracking at low temperature, suitable for internal wiring of cold storage and refrigerators.
