3/10 page SPR-8695TUH USB 2.0 HUB KBD 1. SPECIFICATION 1.1 SCOPE This document describes the detail specifications for “SEJIN STD” TrackBall USB keyboard 1.2. MECHANICAL PECIFICATION 1.2.1 Key switch Operating system: non-lock RUBBER tactile feeling. Travel amount : 3.5±0.5mm with measuring load of 200gf applied. Operating force : 55±25 gf 1.2.2 Key switch Operation Key switch operating parameters should comply with those listed below. Figure on the below represents typical pressure force and displacement values acceptable to SEJIN. The force/displacement curve should not exhibit any significant step or plateau from P2 to the end of full travel. Linear measures are in mm and the values represent the force and displacement of a key switch after it has been preloaded by 10 to 20 grams. Standard: a. Non-lock rubber tactile feeling b. P0 (Preloaded Point) Travel = 0 mm / Force = 10 +10/-5 grams c. P1 (Break over Point) Travel = 1.15 ± 0.25 mm / Force = 60 ± 20 grams d. P2 (Make Point) Travel = 2.66 ± 0.25 mm / Force = P1 - Delta Delta = 45% to 60% of the P1 force, but 20 grams minimum. e. P3 (Normally End Point) Travel = 3.8 ± 0.5 mm / Force = P1 + 10 to 15 grams f. Total Displacement at 100 grams Minimum = 3.2 mm, Nominal = 3.5 mm, Maximum = 4.8 mm Check Point: a. Operating feeling: No definite stickiness or other abnormality shall be allowed. When force is applied with a finger on the key-top center at the rate of three times a second. b. Key-top pulling strength: A key-top should come off after applying a force of 0.5Kg to 8Kg range in the vertical direction.

The measurement will be performed with keys in the home positions. 0.5 mm Max 1.2.9 Rotational Alignment The maximum rotation of key shall be less than 0.5mm as shown below. A<0.5mm (1X1.75 Unit key Max) 0.7mm(1X2 Unit key Max) 1.2.10 End stroke strength End stroke should withstand a static load of 500gf applied on the tip of the key stem in the perpendicular direction for 1minute. 1.2.11 Key-top pull out force The Key-top pull out force shall be 0.5kg or more at normal temperature during initial state. The Key-top shall be not pull out by an ordinary typing operation. 1.2.12 Information for serial number on the back label 0 C A C 0 0 0 0 0 3 Serial No. Production line(A=A line, B=B line, C=C line) Product revision number(A~Z) Produced Month (A~Z)(A=Jan, B=Feb, C=Mar, D=Apr, E=May, F=June, G=July, H=Aug, I=Sept, J=Oct, K=Nov, L=Dec) Last Digit of Year(5=2005, 6=2006, 7=2007) 1.3 ELECTRICAL SPECIFICATION 1.3.1 Power supply voltage DC 5.0V 1.3.2 Power supply current consumption Max 500mA 1.3.3 Insulation resistance More than 100M ohm at 250V DC
