Why Choose KF301?
- 5.08mm pitch — industry-standard spacing for easy wire insertion and screw access
- 300V / 10A rating — suitable for mains-voltage power wiring and high-current loads
- AWG 28–12 wire range — accepts everything from thin signal wires to heavy power cables
- PA66 UL94 V-0 housing — flame-retardant for safety in power applications
- Plug-in design — removable connector block for easy field wiring and maintenance
- 10-pack value — enough for multiple boards or a full project panel
Typical Applications
- Power supply wiring — connect AC/DC power input to PCB without soldering wires directly
- Sensor connections — field-wirable terminals for temperature, pressure, and flow sensors
- Relay and motor control panels — secure wire termination for control wiring
- Arduino / Raspberry Pi projects — clean, removable wire connections for prototypes
- LED driver wiring — connect LED strips and drivers with screw terminals
- Industrial control panels — DIN rail mounted PCB wiring connections
Compatible With
KF301 is compatible with KF128, KF350, Phoenix Contact MKDS 1.5/2-5.08 footprints in many PCB designs. The 5.08mm pitch is the most common pitch for power terminal blocks on Arduino shields, relay modules, and power supply PCBs.
FAQ
Q: What wire gauge does KF301 accept?
A: AWG 28 to AWG 12 (0.08mm² to 2.5mm²). Strip 6–7mm of insulation before inserting the wire.
Q: Is KF301 rated for 220V mains voltage?
A: Yes. KF301 is rated 300V AC/DC, making it suitable for 110V and 220V mains wiring applications.
Q: Can I daisy-chain multiple KF301 connectors?
A: Yes. KF301 connectors can be snapped together side-by-side to create longer terminal strips.
