THRUBEAM LCD MICROMETER, RF656 Series Rev. G (01.02.2008) RIFTEK 1. GENERAL INFORMATION The micrometers are intended for non-contact measuring and checking of position, dis-placement, dimensions of technological objects. 2. BASIC TECHNICAL DATA AND PERFORMANCE CHARACTERISTICS
Model RF656-25 Measuring area, mm 5x25 Distance between transmitter and receiver, L, mm 210 Measurement accuracy 1 , um 5 Maximum sampling rate, Hz 800 Smallest detectable object, mm 0,1 Light source Red LED Output signal analog digital RS232 or RS485 (max 460800 bit/s) 4…20 m (<500 load) or 0…10 V External synchronization input 2,4 – 5 V (CMOS, TTL) Logical outputs 3 outputs, NPN: 100 mA max; 40 max Power Supply, V 5 (4,5…9) or 12 (9…18) or 24 (18…36) Power consumption, W 1,5 Enclosure rating IP64 Operating temperature, ° -10…+50 Weight (without cable), g 200 (transmitter); 150 (receiver) 1 Typical data obtained when a knife edge was used to interrupt the beam 3. EXAMPLE OF ITEM DESIGNATION WHEN ORDERING RF656-25-UART-AN-TTL-OUT-VV--mm Symbol Description UART type of the serial interface (232 or 485) AN attribute showing the presence of Current Loop (I) or U output TTL trigger input (input of synchronization) OUT attribute showing the presence of 3 logical outputs VV supply voltage CC cable gland – CG or socket + cable - CC (Binder 702, IP67, 79-1426-12(15)-08 or 79-1426-72(75)-08) mm cable length, m For example : RF656-232-I-12-CC-5 – serial port - RS232, 4…20 mA output available, supply voltage 12V (9…18V), socket + cable. 5 meters cable lengths. 4. STRUCTURE AND OPERATING PRICIPLE 4.1. The micrometer operation is based on the so-called ‘shadow’ principle. The micrometer consists of two blocks – transmitter and receiver. Radiation of a LED is collimated by a lens. With Page 1/18 , Republic of Belarus
