Product Description

The SMC D-H7A1 is an inline solid-state NPN band sensor, a 3-wire pneumatic position sensor with a 0.5m cable. It operates on 24V DC with a maximum current of 10 mA and features an IP67 rating and LED indicator.

Frequently Asked Questions

What is the SMC D-H7A1 solid state switch used for?

The SMC D-H7A1 is a solid-state NPN band sensor used for pneumatic position sensing in industrial automation. It detects cylinder piston position and outputs a 24V DC NPN signal to a PLC or controller. Typical applications include packaging, material handling, and assembly lines requiring reliable, non-contact sensing.

What are the specifications of the SMC D-H7A1?

The SMC D-H7A1 is a solid-state NPN 3-wire sensor with a 0.5m cable, operating at 24V DC with a maximum current of 10 mA. It has an IP67 rating and an LED indicator for status. The manufacturer part number is D-H7A1, and it is designed for inline band mounting on pneumatic cylinders.

Where to buy the SMC D-H7A1 worldwide?

You can source the SMC D-H7A1 through 3G Electric, a global industrial equipment distributor established in 1990. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply genuine SMC components for pneumatic automation systems.

How to install the SMC D-H7A1 solid state switch?

Mount the SMC D-H7A1 band sensor onto the cylinder body using the provided bracket, ensuring the sensing face aligns with the piston magnet. Connect the 3 wires: brown to +24V DC, blue to 0V, and black to the NPN input. The LED indicator confirms proper alignment and switching. Refer to the SMC manual for detailed setup.
