Specification notes
Q1: What is the TAKEX MC Series?
A: The MC Series consists of U-shaped through-beam mark sensors for detecting register marks on paper, film, and packaging materials.
Q2: What models are available?
A: The lineup includes MC-U2R, MC-U2RTC, MC-U2G, MC-U2GTC, MC-U2B, and MC-U2BTC.
Q3: What is the sensing gap?
A: All MC Series models have a fixed 2 mm sensing gap.
Q4: What light sources are available?
A: The lineup offers 680 nm red, 525 nm green, and 450 nm blue LEDs.
Q5: Which model is suitable for yellow register marks?
A: MC-U2B and MC-U2BTC use blue LEDs and are suited to detecting yellow register marks.
Q6: Does the MC Series require optical-axis adjustment?
A: No. The U-shaped housing fixes the emitter and receiver positions, eliminating separate optical-axis alignment.
Q7: Can sensitivity be adjusted?
A: Yes. All models provide a four-turn non-stop sensitivity adjustment and selectable high/low emitter power.
Q8: Which models provide both NPN and PNP outputs?
A: MC-U2RTC, MC-U2GTC, and MC-U2BTC provide NPN/PNP open-collector dual outputs. The other models provide NPN output.
Q9: What is the protection rating?
A: All MC Series models have an IP67 washable protective structure.
Q10: What applications are suitable for the MC Series?
A: Applications include packaging, food, pharmaceutical, and printing equipment for detecting register marks on wrapping paper, traditional paper, and film.
