Specification notes
Q1: What is the TAKEX ESN Series?
A: The ESN Series consists of 13 mm ultra-thin multi-beam light curtain sensors using separate through-beam transmitters and receivers.
Q2: What models are available?
A: The current lineup includes ESN-T8, T8PN, T12, T12PN, T16, T16PN, T20, and T20PN.
Q3: What is the detecting distance?
A: All current ESN Series models provide a detecting distance of up to 5 m.
Q4: What is the minimum detectable object size?
A: The series detects opaque objects Φ30 mm or larger.
Q5: What is the beam interval?
A: All current models use a 20 mm beam interval.
Q6: What detection widths are available?
A: Detection widths of 140, 220, 300, and 380 mm are available depending on the number of optical axes.
Q7: Are NPN and PNP outputs available?
A: Yes. Standard models provide NPN open-collector output, while PN-suffix models provide PNP output.
Q8: How does the ESN Series output operate?
A: The output turns ON when all optical axes receive light and turns OFF when one or more beams are blocked.
Q9: Can two ESN sensor pairs be mounted close together?
A: Yes. Master/slave synchronization provides anti-interference operation for two adjacent or facing sensor pairs.
Q10: What additional functions are included?
A: The series includes automatic sensitivity compensation, anti-interference, output short-circuit protection, and large high-intensity operation indicators.
