TAKEX PF Series Oil- and Chemical-Resistant PFA Photo Sensors

• PFA oil- and chemical-resistant construction: The sensor body is enclosed in PFA, while the first 2 m of cable from the sensor is protected by PFA tubing for use around oils and various chemicals.
• Suitable for immersed sensing: The PFA construction supports in-liquid applications such as wafer detection inside semiconductor cleaning tanks.
• Through-beam sensing up to 3 m: PF-T3DS and PF-T3S provide 3 m through-beam detection for opaque objects Φ20 mm or larger with response within 0.35 ms.
• 300 mm diffuse reflective models: PF-R03DS and PF-R03S provide 300 mm sensing with a 100 × 100 mm white target and support opaque, translucent, and transparent objects.
• Optional external sensitivity adjustment: Sensitivity adjustment is not built into the sensor. PF-V2 or PF-V2PN external volume units can be added when adjustment is required.

Q1: What is the TAKEX PF Series?
A: The PF Series consists of embedded amplifier photo sensors with PFA-covered bodies and PFA-protected cable sections for oil- and chemical-resistant applications.

Q2: What models are available?
A: The lineup includes PF-T3DS, PF-T3S, PF-R03DS, and PF-R03S.

Q3: Can PF Series sensors be used in liquid?
A: Yes. The PFA construction supports immersed sensing, provided the actual liquid is compatible with PFA and the protected cable area is considered.

Q4: What is the detecting distance of PF-T3DS and PF-T3S?
A: Both are through-beam models with a 3 m detecting distance for opaque objects Φ20 mm or larger.

Q5: What is the detecting distance of PF-R03DS and PF-R03S?
A: Both diffuse reflective models provide 300 mm sensing with a 100 × 100 mm white drawing paper target.

Q6: Can the PF Series detect transparent objects?
A: PF-R03DS and PF-R03S support opaque, translucent, and transparent targets, although actual performance depends on target transmittance and surface conditions.

Q7: What is the response time?
A: All four PF Series models provide a response time of 0.35 ms or less.

Q8: Can sensitivity be adjusted?
A: Sensitivity adjustment is not built into the sensor. The optional PF-V2 or PF-V2PN external volume unit can be used when adjustment is required.

Q9: What is the difference between PF-T3DS and PF-T3S?
A: The main difference is operation mode. PF-T3DS is Dark-ON, while PF-T3S is Light-ON. Their main sensing specifications are otherwise the same.

Q10: What applications are suitable for the PF Series?
A: Applications include wafer detection inside semiconductor cleaning tanks, component detection in automotive anticorrosive spraying processes, and food-material detection in chemical atmospheres such as alcohol.
