8-Position Screwless Push-Button Terminal Block
The Molex 0397000008 is an 8-position, single-level terminal block from the Eurostyle 39700 series. It terminates wire with a screwless push-button clamp — push the button, insert the stripped wire, release. No screwdriver needed, no torque spec to hit. The clamp holds 18-26 AWG solid or stranded wire and the contact is brass with tin plating. Rated 6 A at 150 V, it handles signal-level and moderate power terminations inside an industrial cabinet or control panel. The green polyamide (PA66) housing is through-hole mounted with a horizontal wire entry — wires land parallel to the board.
Push-Button Clamp vs Screw Clamp
The 0397000008 uses a screwless push-button clamp. The alternative in the same Eurostyle 39700 series is a screw-clamp version — same pitch, same current and voltage ratings, same 8 positions. The push-button clamp trades the screwdriver for a thumb-press action; the screw clamp gives you a captive screw you can torque to a spec. For field wiring where speed matters and vibration is low, the push-button clamp saves time. For a high-vibration environment or a permanent install where you want a torqued screw, the screw-clamp sibling is the better pick. Both accept the same 18-26 AWG wire range.
