Product details
The 1289-STR by Keystone Electronics sets new standards in Terminals - Quick Connects, Quick Disconnect Connectors for railway signaling systems, engineered to withstand extreme vibration and temperature cycling. These ruggedized connectors feature patented contact retention systems that maintain connectivity in harsh rail environments. The corrosion-resistant materials ensure reliable performance in all weather conditions.Offering Standard configurations, these terminals meet railway equipment specifications. The double-lock versions prevent accidental disconnection in moving trains.Available in Male variants, the connectors support various signaling architectures. The polarized designs prevent incorrect mating in complex control systems.Precision-controlled to 0.250" (6.35mm) dimensions, the contacts maintain stable connections. The reinforced designs withstand mechanical shock in rail applications.The 0.032" (0.81mm) material specification ensures durability. The cold-forged construction provides superior mechanical strength.The 0.470" (11.94mm) engagement dimension maintains constant contact pressure. This parameter is critical for maintaining signal integrity in moving trains.At 0.710" (18.03mm), these terminals meet railway equipment space constraints. The compact design allows installation in tight equipment cabinets.Solder methods comply with railway wiring standards. The screw-clamp versions accommodate solid and stranded conductors.The Non-Insulated options meet stringent railway requirements. The flame-retardant materials prevent fire propagation in tunnel installations.Through Hole installations address various rolling stock requirements. The DIN rail-mounted versions enable quick installation in control panels.Utilizing Brass, the contacts achieve optimal performance. The nickel silver alloys provide excellent corrosion resistance.Tin platings provide specialized surface properties. The tin-plated versions offer reliable performance in humid environments.
