UL 60335 -2 3.5-4.5 Years Age Test Probe With Center Rotate Pin To Simulate Fingers
Product Overview:
This UL 60335-2-24 Figure 101.DVA.1 Articulated Probe 3.5-4.5 Years Age SN2210-49 is designed and manufactured meet the requirements of the standard of UL60335-2-24 Figure 101.DVA.1.
It is used to verify that the moving parts of products for refrigeration or similar use may not be touched by children and the moving parts of which may cause personal injury.

Notes: 1-The probes were designed with a center pin to rotate the hand with respect to the lower arm. That motion can be equivalently represented by rotating the probe. 2-The finger “tip” is developed to match the dimensions of the UL articulated probe. The diameter from the tip to the first joint them tapers from the tip dimensions to the finger diameter. The joints are spaced equally along the finger length. 3- The probe is designed to permit the hand to “bend” with respect to the arm using a hinge pin located 6mm (0.24 in) from the hand length (wrist end) and the hand is restricted in bending not more than 90° with respect to the arm. a If the upper arm is required to evaluate a part it shall consist of a flexible tube attached at the end of the lower arm, as the exact position of the elbow cannot be readily determined from the data points chosen. |
