Product Description

The SMC D-Y59A is an inline solid state auto switch, a pneumatic position sensor with an NPN output. It operates at 28 V DC or less and has a maximum load current of 40 mA or less. This IP67-rated switch is designed for direct mounting on pneumatic actuators to detect cylinder piston position.

Frequently Asked Questions

What is the SMC D-Y59A inline solid state auto switch used for?

The SMC D-Y59A is a pneumatic position sensor used to detect cylinder piston position in industrial automation. It mounts directly on pneumatic actuators and provides an NPN output signal to a PLC or controller, enabling precise monitoring of cylinder stroke in manufacturing and process equipment.

What are the specifications of the SMC D-Y59A?

The SMC D-Y59A is an inline solid state auto switch with NPN output, rated for 28 V DC or less and a maximum load current of 40 mA or less. It has an IP67 enclosure rating for dust and water resistance. The manufacturer part number is D-Y59A.

Where to buy the SMC D-Y59A worldwide?

3G Electric supplies the SMC D-Y59A worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this pneumatic position sensor to any country.

How to install the SMC D-Y59A on a pneumatic cylinder?

Mount the SMC D-Y59A directly on the cylinder body using the provided bracket or band, aligning the sensor with the piston magnet. Connect the NPN output to a 24 V DC PLC input, ensuring voltage stays at 28 V DC or less. Verify IP67 sealing and test piston position detection before operation.
