The 3780-60-2 is a Test Lead with hook clip to free end connector. Minigrabber? test clip (one end) allows customization of the open end. Hook material is gold plated beryllium copper for superb strength and low contact resistance to ensure signal integrity. For added safety, the grabber body material is fire retardant nylon 6. Stainless steel grabber compression spring resists corrosion and retains a firm feel throughout the life of the grabber. Flexible 20-gauge multi-stranded wire is molded directly to the grabber actuator cap and pin tip plug for durability.
