Solder these relays directly to printed circuit boards using their solder pin terminals.

With no moving parts, these solid state relays last longer, switch faster, and are quieter than mechanical relays. They interface between your controller and components to isolate input and output circuits, which protects components from voltage spikes, amplifies the relay’s signal, and reduces interference for reliable transmission.

Also known as an air-to-electric switch, this relay converts an air signal to an electric signal.

The circular pin terminals plug into relay sockets for easy installation.

Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation.

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding.

Mount these terminals on a threaded screw or stud for a more secure connection than spade and hook terminals. They are noninsulated, so you can easily inspect the wire connection.

Mount these elongated ring terminals on a range of threaded screw and stud sizes—their connection is more secure than spade or hook terminals.

For easy crimping, lay wire into the open barrel instead of threading it through a closed barrel.

With a heat-resistant PVDF cover on the barrel, these terminals are best for high-temperature applications where you want to prevent short-circuiting with nearby wire.

When heat is applied, the enclosed solder melts, creating the most secure and electrically conductive connection we offer. The plastic insulation also shrinks when heated, forming a seal to keep out water and contaminants.

Thicker than standard ring terminals and noninsulated, these terminals are best when you need durability and to easily inspect the wire connection.

A plastic cover on the barrel provides electrical insulation to prevent short-circuiting with nearby wire. These terminals have a serrated edge on the inside of the ring that grips the mounting screw for a secure hold.

Add strength and stability to stranded wire to protect it from damage and speed insertion into terminal blocks. These terminals are noninsulated, so you can easily inspect the wire connection.

A plastic cover on the barrel provides electrical insulation to prevent short-circuiting with nearby wire. Convenient for applications that require frequent connections, these terminals slide together and pull apart with ease.
