Phoenix Contact has unveiled low-profile PCB terminal blocks in three user-friendly spring-lever options: IL series, EL series, and LL series. The terminal blocks are 8 to 11 mm high and boast spring-wire termination. That allows users to insert solid or ferruled wires into any of the connectors without opening the spring connection.
The new SPTAF 1 connectors from Phoenix Contact feature a low-profile body and are available in 3.5- or 5.0-mm pitch, with two to 16 positions per connector. The SPTAF 1 connectors are rated to 8 A and 300-V UL. Moreover, they are compatible with 16 to 24 AWG wires.
The IL series of terminal blocks — targeted at the applications with the tightest fit — features an internal lever that keeps overall connector height to just 8 mm. So for stranded wire, a screwdriver can quickly and easily open the connection.
The EL series of PCB terminal blocks, which is 10 mm high, doesn't require any tools; the user can push an external lever with a finger.
Finally, the LL series locks the connector into an open position, which allows the installer to use both hands for wiring. These PCB terminal blocks are less than 11 mm high and don't require any tools, either.
