Specification notes
Q1: What are the TAKEX US-T50 and US-T50PN?
A: They are through-beam ultrasonic sensors that use an opposing transmitter and receiver for object presence and passage detection.
Q2: What is the detecting distance of the US-T50/US-T50PN?
A: The detecting distance is 500 mm or less.
Q3: What is the difference between US-T50 and US-T50PN?
A: US-T50 provides an NPN output, while US-T50PN provides a PNP output. Their main sensing specifications are otherwise the same.
Q4: Can the US-T50/US-T50PN detect transparent film?
A: Yes. Transparent film detection is one of the intended applications, including materials with different transparency, colors, and materials.
Q5: Can the US-T50/US-T50PN detect transparent trays?
A: Yes. The US-T50 is used for detecting the passage of transparent trays.
Q6: What power supply is required?
A: Both models operate from 24VDC ±10% with ripple of 10% or less.
Q7: What is the response time?
A: The response time is 10 ms or less.
Q8: Can sensitivity be adjusted?
A: Yes. The receiver includes a sensitivity adjustment function for setting the sensor according to the target and installation conditions.
Q9: What is the protection rating?
A: The protective structure is IP54. Water drops must not remain on the sensing head, and ambient wind speed should be 1 m/s or less.
Q10: How do I choose between US-T50 and US-T50PN?
A: Select US-T50 when an NPN output is required and US-T50PN when a PNP output is required by the control system.
