Two-Position Screwless Terminal Block for PCB Mount
The Molex 0397000202 is a 2-position Eurostyle 39700 terminal block designed for direct PCB mounting. It uses a screwless push-button clamp for wire termination, accepting 18-26 AWG wire. The green polyamide (PA66) housing is UL94 V-0 rated by extension of the series material, and the brass contacts are tin-plated for solderability and corrosion resistance in dry indoor use.
How the Push-Button Clamp Changes Field Wiring
Instead of a screw, the 0397000202 uses a push-button clamp: press the orange button to open the wire entry, insert the stripped conductor, release the button to clamp. This eliminates over-torque damage to the housing and speeds wiring compared to a screw-clamp block. The clamp material is stainless steel, so it resists corrosion in humid cabinet environments. Wire orientation is top entry — wires enter perpendicular to the PCB surface, which suits a board mounted flat in an enclosure with wiring routed above the board. The single-level layout keeps the profile low.
Position Count and Series Siblings
The 0397000202 is the 2-position member of the Eurostyle 39700 series. The same pitch and termination style is shared by the 3-position 0397000302 and the 1-position 0397000102. There is no difference in current rating, voltage rating, or wire range across the series.
