ASCO P494A0021400A00, Reed Pneumatic Position Detector, IP67, 5 → 50V, 494, with LED indicator
Part No. P494A0021400A00
The ASCO P494A0021400A00 is a Series 494 mini reed-switch position detector for cylinders with T-profile grooves. It operates across a 5-50 V supply range, has an LED switching indicator and is sealed to IP67 for general industrial environments. Genuine ASCO detector, supplied in the UAE by General Tech Services LLC. Pricing is quote-based. Request a quote in under a minute - call +971 6 543 6933.
The ASCO P494A0021400A00 uses a reed switch to detect the magnet on a cylinder piston through the cylinder barrel. When the piston reaches the sensing position, the magnetic field operates the reed contact, while the built-in LED provides a visual indication of the switching state during setup and troubleshooting.
The detector operates across a wide 5-50 V supply range and provides a straightforward sensing solution for factory automation, material handling and assembly equipment. Its IP67 protection helps protect the detector against dust and temporary water immersion in suitable industrial environments.
The detector is designed for T-profile grooves, while the supplied information also identifies compatibility with profile, tie-rod and round barrels when the appropriate mounting kit is used. Mounting kits are ordered separately. Before ordering, confirm the cylinder groove profile, supply voltage, controller requirements and mounting arrangement with General Tech Services LLC.

Frequently Asked Questions
What is the ASCO P494A0021400A00?
It is a Series 494 mini reed-switch cylinder position detector with IP67 protection, a 5-50 V operating range and an LED switching indicator.
How does the P494A0021400A00 detect the cylinder position?
The reed switch responds to the magnetic field from the cylinder piston magnet through the cylinder barrel. The built-in LED indicates the switching state.
Do I need a mounting kit?
Mounting kits are ordered separately. The required mounting arrangement depends on the cylinder type and groove configuration. Send your cylinder series and bore to General Tech Services LLC for compatibility confirmation.
Can the P494A0021400A00 work on AC and DC?
The supplied product information describes a 5-50 V operating range. Reed switches can be used with AC or DC within their specified electrical ratings, but the load current and controller requirements should be confirmed before installation.
How many detectors does one cylinder need?
The number depends on the machine's control requirements. Two detectors are commonly used for retracted and extended positions, while some machines may use an additional detector for an intermediate position.
How do I choose the P494A0021400A00 or another Series 494 detector?
Choose the detector based on the cylinder groove profile, electrical requirements, supply voltage and connection arrangement. Send your cylinder details and detector part number to General Tech Services LLC for compatibility confirmation.
What is the difference between a reed switch and a magneto-resistive detector?
A reed detector uses a magnetic contact switch and offers a straightforward sensing solution across its specified voltage range. A magneto-resistive detector uses solid-state sensing without mechanical switching contacts and can be suitable for applications where high switching cycles or contact wear are concerns.
How do I get a price and lead time?
Pricing is quote-based. Call General Tech Services LLC on +971 6 543 6933 or submit the Request a Quote form.
