Values are sensed for white paper. 2. These values apply when a E39-R12 Reflector is used. The MSR function is built-in. The reflected light from the object being measured may affect the sensing accuracy, so adjust the threshold value before use. 3. The beam radius is the value for the middle measurement distance and indicates a typical value for the middle sensing distance. The radius is defined by light intensity of 1/e2 (13.5%) of the central light intensity. Light will extend beyond the main beam and may be affected by conditions surrounding the object being measured. 4. The E3C-LR12 has a fixed beam size (the focus point cannot be changed). 2 E3C-LDA Series Photoelectric Sensors with Separate Digital Amplifiers (Laser-type Amplifier Units) Amplifier Units Type External-input models Model NPN output E3C-LDA21 Item PNP output E3C-LDA51 Twin-output models ATC-output models Analog-output models E3C-LDA7 E3C-LDA11 E3C-LDA6 E3CLDA11AT E3C-LDA6AT E3C-LDA11AN E3C-LDA9 E3C-LDA41 E3C-LDA8 E3CLDA41AT E3C-LDA8AT E3C-LDA41AN Supply voltage 12 to 24 VDC ±10%, ripple (p-p) 10% max.
