Plug-In Terminal Blocks With Screw Flanges Withstand Vibration

Besides anti-vibration applications, the new CTBA/FL pluggable terminal blocks are also ideal for use where a heavy cable on the female part could break the connection with the PCB-mounted male component. Two sizes are available offering 5 and 5.08mm pitch with 0.2 to 0.4mm² cable entry (24 to 12AWG).

CTBA/FL flanged pluggable terminal blocks are available in solid blocks from 2 to 22 poles and can be supplied in vertical and horizontal orientations for both the male PCB header and the female connector. The captive screws in the flange of the female part ensure the connection is 100 percent reliable even in hostile and high vibration applications.

Moulded from green UL94V0 flame retardant PA66, additional features include professional rising clamp terminals, anti-solder wicking and polarised mouldings to ensure correct connection as well as VDE, CE and UL approvals. Guided pin alignment ensures a better fit for the male header into the drilled holes on the PCB.

Specifications include 16A rating (VDE at 380V, UL at 300V), dielectric strength of 2000V AC, insulation resistance ≥2MΩ and working temperature from -40 to +105°C. Pin/terminals are tinned phosphor bronze while rising clamp terminals are nickel plated brass. Captive terminal screws are M3 zinc plated.

Applications for the new CTBA/FL flanged pluggable terminal blocks include machinery control, lift control, hoists and anything that moves or is liable to mechanical shock.
