HPQ-D11 AZBIL Photoelectric Switch NEW

Product Description:

HPQ-D Series Liquid Leak Detection Sensors with Self-contained Amplifier:

Suitable for export equipment with CE marking and UL certification.

NO/NC output

NPN/PNP output

See HPF-D040 series for inherently safe product

Overview?

The built-in amplifier in the HPQ-D Series eliminates the need for liquid absorbing paper. Sensor body and cable have PFA protection so it is usable with a variety of liquids including acids or alkaline liquids, IPA (isopropyl alcohol), pure water, flourinert, galden and many others. After leak detection, simply wipe off the detector surface, easy maintenance compared to sensors with detection tape or liquid absorbing material. Green LED operation indicator for normal state and red for leakage can be checked from the top or side. PVC sensor brackets are available for acidic and alkaline liquids and PFA (partially SUS) brackets are available for organic solvents..

Benefits?

Sealed, Chemically Resistant Materials - 13mm circular sensor pancake lays on bottom of semiconductor wet process tool and detects liquid leak or spill by refraction light principle

Body is Teflon(r) PFA material with IP67 sealing and the mounting bracket assembly is CPVC.

Quick Detection Minimizes Environmental Impact and Messy Cleanup - Typically, 1ml of liquid contact with the optical focal point will trigger the signal change.

Fail Safe Design - Output current is conducted in normal dry conditions and will turn off in the presence of liquid.

The sensor can be used with any pan material color.

PNP and NPN output versions are available.

Condition Indication Using Easy-to-View LED's - Green LED indicates normal condition, orange LED indicates liquid is detected.

Low Initial and Operational Cost - The HPQ-D series is priced very aggressively and will require little maintenance unlike other prevailing technologies.
