Stamped contacts and terminals are positioned inside overmolded M8/M12 connector bodies to provide sealed, ready-to-plug electrical connections for sensors, I/O modules, industrial communication devices, and automation networks.
when
GROMAX
is a good fit
The part has function-critical geometry
Small changes in width, slot size, contact height, bend angle, tab location, or flatness can affect mating and assembly performance.
Material Selection Affects Performance
Copper alloys, brass, beryllium copper, nickel silver, stainless steel, and other conductive materials each behave differently during forming and use.
Material choice affects:
• Conductivity
• Spring behavior
• Strength
• Formability
• Corrosion resistance
• Fatigue life
• Plating compatibility
Plating Matters
Tin, nickel, silver, gold, and RoHS-compliant finishes can affect contact resistance, solderability, wear, corrosion resistance, and final fit.
Plating buildup should be considered early because it can change slot width, contact pressure, and insertion force.
Spring Force Must Stay Consistent
Battery contacts, fuse clips, relay contacts, and spring terminals may require controlled preload, deflection, contact force, and resistance to permanent set.
Burr Direction Is Function-Critical
Burrs and sheared edges can affect:
• Mating surfaces
• Electrical contact
• Insertion
• Operator handling
• Overmolding
• Mating-part wear
Repeatable Production Is Required
Progressive tooling is often a strong fit when the program needs stable dimensions, consistent forming, controlled plating, and dependable production volume.
