Design of Card Separation Gap in Card Separation Mechanism

In the card machine, the card separation gap formed by the card separation axis at the front end of the card in the forward direction of the card and the card separation flap is the key to the separation mechanism. Changes in the gap width and relative position affect the card separation effect ......

Five key technologies of LED display quality

1. Brightness and viewing angle The brightness of the display mainly depends on the luminous intensity and LED density of the LED. In recent years, LEDs have emerged with new technologies in substrates, epitaxy, chips, and packaging. In particular, the stability and maturity of indium tin oxide ( ......

Honeywell sensors in the transportation industry

The Hall effect rotary position sensor uses a magnetic field instead of a mechanical brush or dial and is dedicated to measuring the angular position of moving parts. This product uses a magnetically biased Hall-effect integrated circuit (IC) to detect the rotational motion of the actuator shaft ......
