It is rated for 150V and 2A per pole under UL 1059, with a conductor acceptance range of 20 AWG to 16 AWG (1.3mm² CSA) for both solid and stranded wire. The plug component features a compact, flush-mount design with overall dimensions of 12.5mm height, 17mm width, and a length proportional to its 4-way configuration. It is designed to mate with a corresponding unshrouded header, available in a standard 12.5mm height or a 16.5mm high wide-base version for enhanced mechanical stability. Connection is achieved via a push-in spring clamp mechanism, requiring no special tools for wire insertion. The specified wire stripping length is 8.5-10mm. Mechanical performance is defined by an insertion force of 2.5N per pole and a minimum withdrawal force of 4.5N per pole, ensuring secure wire retention. The operating temperature range is -40°C to +110°C. Materials include a lead-free tin-plated steel clamping spring, a 94V0 flame-retardant polyamide housing, and tin-plated copper alloy pin terminals. This terminal block system is intended for signal and control applications where tool-less installation is beneficial. Typical use cases include automation and drives technology, HVAC control boxes, thermostat controls, and equipment for sound recording or broadcast production. The product is UL listed (File E60677) to the UL 1059 standard for terminal blocks. The 1986716-4 specifically denotes the 4-position flush-mount plug, which must be paired with a compatible header (e.g., 1986717-4 or 1986718-4) to form a complete, disconnectable wire-to-board interface. ## Specifications | Parameter | Value | |---|---| | Pitch Spacing | 3.5mm | | Product Range | - | | Rated Current | 2A | | Rated Voltage | 150V | | Wire Size (Awg) | 20AWG to 16AWG | | No. Of Positions | 4Ways | | Wire Size Awg Max | 16AWG | | Wire Size Awg Min | 20AWG | | Conductor Area Csa | 1.3mm² | | Wire Connection Method | Push In | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2081201/) ## **Introducing** ## 3.5mm Spring Type Flush Mount Plug with Mating Unshrouded Header The new 3.5mm Spring Type Flush Mount Plug with Mating Unshrouded Header now allows for a quick and easy way to insert the wire in signal applications without the use of special tools.
