Characteristic of NJL5820R of sensor of photoelectricity of analytic reflex type reachs a function

April 26, 2018 admin Comments 0 Comment

[introduction] NJL5820R and commendatory baffle-board (stripe lens) the signal of 2 photographs number that combination can obtain 90 degrees of phase shift, can detect simply thereby piece rotate (mobile) direction and position. Detect rise and drop what give 2 photographs signal, with respect to the 1/4 resolution that can obtain baffle-board design cycle, the physics that compares stripe lens measures precision to having more the measurement of high accuracy.

[characteristic]

1. can detect according to output of signal of 2 photographs number piece rotate (mobile) direction and position

NJL5820R and commendatory baffle-board (stripe lens) the signal of 2 photographs number that combination can obtain 90 degrees of phase shift, can detect simply thereby piece rotate (mobile) direction and position.

Detect rise and drop what give 2 photographs signal, with respect to the 1/4 resolution that can obtain baffle-board design cycle, the physics that compares stripe lens measures precision to having more the measurement of high accuracy.

2. contains glow element (LED) drive electric current inside, low consumption electric current is designed

NJL5820R is the IC getting light that constituted electric current of tall sensitivity, low consumption and high output infra-red LED, realized equipment of batteries power supply also function of electric current of spendable low consumption. The drive electricity that needs left and right sides of market product 1/5 only can work.

3. sensor has strong dovish sex (Robust) , fluctuant to what be apart from between stripe lens can maintain what stabilize relatively to detect function

Detecting when linear shift and the position when rotating, maintain the distance between sensor and stripe lens very hard changeless. NJL5820R is fall when the distance happening is fluctuant circumstance between sensor and stripe lens, its suffer smooth component to also can detect reflex of classics baffle-board catoptric, after serving as the photocurrent of generation paragraph the fiducial voltage of comparator, maintained fluctuant to the distance relative stability already so, duty and phasic difference do not have wave motion basically also.

4. does not suffer magnetic field interference

Because be the sensor of optical mode, won’t be come from the interference of electric machinery magnetic field so. Finding a place for need not consider to install the position when sensor, and also need not undertake magnetic field is analysed when the design.
