QLA764B-3G datasheet


Description :

For right-angle and vertical viewing, the QT Optoelectronics LED circuit board indicators come in T-3/4, T-1 and T-1 3/4 lamp sizes, and in single, dual and multiple packages. The indicators are available in AIGaAs red, high-efficiency red, bright red, green, yellow, and bi-color at standard drive currents, as well as at 2 mA drive current.

To reduce component cost and save space, 5 V and 12 V types are available with integrated
resistors. The LEDs are packaged in a black plastic housing for optical contrast, and the housing meets UL94V-0 flammability specifications.

Features :

First color indicated is on top, the second is in the middle, and the third is on the bottom.
For example: QLA764B-YGH has YEL(top)/GRN(middle)/B. RED(bottom).

UAF2115 Indicator

Description :

The input signal of the UAF 2115 derived from a reed contact or a proximity switch ( dropout oscillator ) placed, for example, at the drive shaft of the gearbox and which supplies one rectangular pluse per shaft rotation.

The monostable filp-flop is triggered by the trailing edge of the input signal.
