Excelta DN-3C-SA-SE Tweezers - Straight Fine Point - Reverse Action - Anti-Mag. SS
Excelta DN-3C-SA-SE Tweezers — Straight Fine Point, Reverse Action, Anti-Magnetic Stainless Steel
The Excelta DN-3C-SA-SE is a reverse action (normally open) tweezer with a straight, very fine point tip, crafted from anti-magnetic stainless steel. Designed for precision electronics assembly, the DN-3C-SA-SE features a squeeze-to-close mechanism — ideal for holding small components in place during soldering, inspection, or placement without requiring constant grip pressure.

What Is Reverse Action?
Standard tweezers are normally closed — you squeeze to open. Reverse action tweezers are the opposite: they are normally open and close when you squeeze. This allows you to grip a component and hold it without maintaining hand pressure, reducing fatigue during extended assembly or inspection tasks and preventing accidental drops when your grip relaxes.
Industries & Applications
- SMT and PCB assembly
- Component placement and handling
- Rework and repair of fine-pitch surface mount devices
- Laboratory and cleanroom component handling
- Medical device and aerospace electronics assembly
Frequently Asked Questions
What makes the DN-3C-SA-SE a reverse action tweezer?
Reverse action tweezers open when relaxed and close when squeezed, allowing you to hold components without continuous grip pressure. This reduces hand fatigue and prevents accidentally releasing parts.
What does SA-SE mean in the Excelta part number?
SA indicates anti-magnetic stainless steel construction, and SE refers to the finish/grade. Anti-magnetic steel is preferred in electronics environments where magnetic attraction to components could interfere with placement or inspection.
Are these tweezers ESD safe?
These tweezers are made from stainless steel and are not ESD-rated. For ESD-sensitive component handling, Excelta offers ESD-safe tweezer options. These are suitable for standard electronics assembly where ESD protection is handled by other means (mats, wrist straps, etc.).
What tip style is best for fine-pitch SMT work?
The straight very fine point (3C pattern) is one of the most versatile tips for SMT work, suited for 0402, 0603, and larger passives as well as fine-pitch ICs. For ultra-fine 0201 or 01005 components, an ultra-fine tip variant may be preferred.
How do I maintain Excelta stainless steel tweezers?
Wipe tips clean after use to remove flux residue and solder. Avoid dropping tweezers — the fine tips are precision-ground and will deform on impact. Store in a protective case or tip cover to maintain point geometry.
