Dimension and tolerancing per ASME Y14.5M-1994. 2. Dimension in Millimeters. 3. Dimension D does not include mold flash, protrusion or gate burrs. Mold flash, protrusions or gate burrs shall not exceed 0.25mm per end. Dimension E1 does not include interlead flash or protrusion. Interlead flash or protrusion shall not exceed 0.25mm per side. D and E1 dimensions are determined at datum H. 4. The package top may be smaller than the package bottom. Dimensions D and E1 are determined at the outermost extremes of the plastic body exclusive of mold flash, tie bar burrs, gate burrs and interlead flash, but including any mismatch between the top and bottom of the plastic body. D and E1 dimensions are determined at datum H. 5. Datums A & B to be determined at datum H. 6. These dimensions apply to the flat section of the lead between 0.08mm and 0.15mm from the lead tip. 7. Dimension “b” does not include dambar protrusion. Allowable dambar protrusion shall be 0.08mm total in exceed of the “b” dimension at maximum material condition.

working principle FIGURE 1 As shown in Fig.1, via an emulating SPI communication interface CON , information from the mainframe is transmitted to the encoder circuit board “Encode” at a communication speed of 122Hz. When the MCU on the encoder board identifies the starting position of the data, it outputs Manchester code in an encode format of “header code + address code + condition + check code”. the following operating mode is used: the transmitting module transmits several sets of identical data in 0.6 second, then, after 20 seconds of pause, receives data again from the mainframe and repeats the above transmitting process. Table 1 is the main characteristic parameters of the transmitting module.。 Parameter Symbol Condition Value u nit mintyp max PowerSupply Modulation input Voltage Vcc 3.3 3 12 V Outout Power Pout +10 dBm Supply current Idd 18 mA Supply voltage Range Data Rate Ddate 10 Kbps Work Ffrequency Frf 433.92 MHz Modulate ASK Operating temperature -20°C～+60°C C O N
