Eighteeth E-Connect S — Cordless Endo Motor with Built-In Apex Locator

The Eighteeth E-Connect S is a professional-grade cordless endodontic motor that combines a precision brushless induction motor with a multi-frequency apex locator in a single ergonomic handpiece. It streamlines root canal treatment by uniting canal preparation and working-length measurement — used together or independently — so you can shape and measure in real time without reaching for a separate apex locator. FDA-cleared (510(k) K201993) and built for everyday clinical reliability, the E-Connect S delivers premium endo functionality at a fraction of the cost of flagship systems.

Built on a brushless induction motor platform, the E-Connect S produces smooth, low-vibration performance across a 120–1,000 rpm speed range with torque adjustable from 0.5 to 4.0 Ncm. The 360°-rotatable 1:1 ECAN mini contra angle provides unobstructed access to every quadrant, while the OLED display rotates for comfortable left- or right-hand use. Eleven memory programs (M0–M10) come pre-loaded with common rotary and reciprocating file-system settings and can be fully customized or updated via USB.

An integrated safety system — Auto Start & Stop, Apical Slow Down, and Apical Reverse — works in real time to help protect the cemento-dentinal junction, reduce procedural errors, and minimize the risk of file separation. A visualized apex bar chart with a zoom-in function gives clear, real-time feedback on file-tip position throughout the procedure, with rated apex-location accuracy of ±0.5 mm.

Key Features and Benefits

• Brushless induction motor — reliable, low-noise operation with a longer working life than conventional brushed motors
• Built-in multi-frequency apex locator — work integrated with the motor, or use the included measuring wire for standalone canal-length measurement; rated ±0.5 mm accuracy
• Auto Start & Stop — the motor engages when the file enters the canal and stops automatically when withdrawn, reducing clinician fatigue
• Apical Slow Down — motor speed reduces automatically in the apical region to help preserve the cemento-dentinal junction and prevent file separation
• Apical Reverse — user-defined reverse trigger at the preset apical point for added safety control
• 4 working modes — FWD, REV, REC (reciprocation, 30°–370° adjustable) and ATC (Adaptive Torque Control)
• 360°-rotatable 1:1 ECAN mini contra angle — one-piece body for easy sterilization and all-quadrant access
• Torque calibration — helps ensure precise, consistent torque output across procedures
• OLED ambidextrous display — high-contrast screen rotates for left- or right-hand use
• 11 memory programs (M0–M10) — pre-loaded with popular file-system presets including ProTaper, WaveOne, Reciproc, Mtwo, OneShape, OneCurve, 2Shape and more; fully customizable
• Open file-system compatibility — not locked to a proprietary file brand; use the NiTi rotary or reciprocating files you already trust (2.35 mm ISO 1797-1 Type 1 shaft)
• Visualized apex bar chart with zoom — clear real-time positional feedback during canal measurement
• USB firmware upgrades — keep the device current with the latest software releases
• Lithium-ion battery (3.7 V, 1,500 mAh) — heavy-duty charge for extended clinical use, roughly 4-hour full charge

Clinical & Workflow Advantages

• Shape and measure in one motion — integrated apex control means fewer instrument changes and a smoother, faster workflow chairside
• Four true working modes — FWD and REV for continuous rotation, REC for reciprocation with adjustable 30°–370° angles, and ATC, which reciprocates to relieve file stress when the torque limit is reached before returning to forward rotation — helping extend file life
• Ambidextrous, rotate-anywhere design — the rotating OLED screen and 340°-adjustable contra angle keep the display readable and the head positioned for any tooth or hand preference
• Built to sterilize — the contra angle, lip hook, file clip, and insulating sleeve are autoclavable up to 134 °C

Why Choose the E-Connect S

The E-Connect S hits the sweet spot between capability and value. It offers the integrated motor-plus-apex-locator workflow found on premium units like the Dentsply X-Smart Pro+ and J. Morita Tri Auto ZX2 — the E-Connect S is, in fact, cleared by the FDA as substantially equivalent to the Tri Auto ZX2 — but at a mid-market price point that makes advanced endodontics accessible to general practices and growing clinics. Its rated apex-locator accuracy of ±0.5 mm is tighter than the ±1.5 mm/+0.5 mm figure cited for the Tri Auto ZX2 predicate in the same FDA comparison.

Unlike closed systems tied to a single manufacturer's files, the E-Connect S is an open-platform motor: it drives virtually any NiTi rotary or reciprocating file with a standard 2.35 mm ISO shaft, so you keep using the files your clinicians already prefer. Add real safety automation (Auto Start/Stop, Apical Slow Down, Apical Reverse), free USB firmware updates, and a fully autoclavable head, and the E-Connect S becomes a dependable everyday workhorse rather than a compromise.
