K-840 infrared photocell / R Macesa (Model: K-840 / R) WITH PHOTO INFRARED BARRIER CATADRIÓPTICOS 5 mts. The K-840 Photoelectric work for reflection, to a maximum distance of 5 meters. It is used as a mirror reflecting retro-reflector of 80 m / m in diameter and REF MR-6 (other sizes on request). Each photocell is supplied with a reflector.

Built on the same photo-cell, is the amplifier, the output and relay optics. The standard voltages are: 220,110,24 and 12 V. a.c. and d.c. It has no external control setting, so its use is very simple. A red LED lights to befocused to the reflector, fading to detect an object. Fixation is done with the help of the squadron Ref. 74800, rotated in both directions and that can be placed on both sides of the photocell. The photocell is supplied without a buzzer. Basic models: K-840 / R: Food to 220,110,24 and 12 V. a.c. or d.c. (50-60 Hz). Output relay. Key Features: Relay output: 2 Amp Inverter. 250 V. Relay switching frequency: 30 Hz Transistor switching frequency: 100 Hz Voltage output (transistor): 98% of input. Rectangular waveform. Maximum current 100 mA. Size: 9x6x21 cm. mas informacion
