Long-Range Background Suppression Photo Sensors

TAKEX DL-S Series background suppression photo sensors use a two-segment photodiode for distance-based detection up to 1 or 2 m.
The lineup offers red or infrared LEDs, NPN/PNP dual outputs, 2 ms response, cable or M8 connection, optical distance adjustment, and IP66 protection.

Features

Up to 2 m long-range sensing: The lineup provides 1 m and 2 m sensing ranges for long-distance reflective detection.
Two-segment photodiode detection: Distance is determined from the position of received light, reducing the effects of target color, material, background reflection, and sensor contamination.
Red or infrared light source: DL-S100R, DL-S100R-J, and DL-S202R use 650 nm red LEDs, while DL-S202 and DL-S202-J use 880 nm infrared LEDs.
NPN/PNP dual outputs: All models operate from 12–24VDC and provide both NPN and PNP open-collector outputs rated up to 100 mA at 30VDC.
2 ms response and IP66 protection: The series provides a response time of 2 ms or less with an IP66 protective structure.

Specification notes

The 1 m and 2 m models have different setting ranges: 1 m models can be set from 0.2 to 1 m, while 2 m models can be set from 0.2 to 2 m using 200 × 200 mm white drawing paper.
Light source and connection vary by model: red-light models use a 650 nm LED, infrared models use an 880 nm LED, and selected models use an M8 connector.
The output transistor turns off if a load short circuit or overload occurs. After checking the load condition, power must be reapplied.

FAQ

Q1: What is the TAKEX DL-S Series?
A: The DL-S Series consists of long-range background suppression photo sensors using limited-range reflective detection with a two-segment photodiode.

Q2: What models are available?
A: The lineup includes DL-S100R, DL-S100R-J, DL-S202R, DL-S202, and DL-S202-J.

Q3: What is the maximum detecting distance?
A: The maximum detecting distance is 2 m. The 1 m models cover 0.1–1 m, while the 2 m models cover 0.1–2 m.

Q4: Why is detection less affected by target color?
A: The two-segment photodiode determines distance from the received-light position rather than light intensity alone, reducing the influence of target color and material.

Q5: What light sources are available?
A: DL-S100R, DL-S100R-J, and DL-S202R use 650 nm red LEDs. DL-S202 and DL-S202-J use 880 nm infrared LEDs.

Q6: Does the DL-S Series provide both NPN and PNP outputs?
A: Yes. All models provide NPN/PNP open-collector dual outputs rated up to 100 mA at 30VDC.

Q7: What is the response time?
A: The response time is 2 ms or less.

Q8: Can the sensing distance be adjusted?
A: Yes. A five-turn optical NEAR/FAR adjustment is provided.

Q9: Are M8 connector models available?
A: Yes. DL-S100R-J and DL-S202-J use M8 connectors and can be combined with straight FBC-4R2S or angled FBC-4R2L 2 m connector cables.

Q10: What applications are suitable for the DL-S Series?
A: The series is intended for general machinery, logistics, automotive and parts processing, food, and pharmaceutical equipment. DL-S202 is also shown for long-distance detection of tires in different sizes.
