The rising cage clamp is a straightforward, field-proven termination — you strip the wire, insert it into the clamp opening, and tighten the screw. The clamp rises to pinch the conductor against the current bar. It accepts 16 to 28 AWG, which covers everything from 16 AWG power feeds down to 28 AWG signal wires. The clamp and screw are copper alloy with nickel plating, and the contact surface is tin-plated copper alloy — standard for a general-purpose terminal block where you're terminating solid or stranded copper wire. No special tooling beyond a screwdriver; the same block works for a prototype board and a production run. At 3.50 mm pitch, the two positions need 7.00 mm of board edge for the pin row. The through-hole mounting gives a solid mechanical anchor — the pins solder into plated holes and take the strain of the terminated wires without relying on the solder joint alone. The side-entry orientation means the wires run parallel to the board surface, so plan for clearance around the block for the screwdriver access and wire bend radius. The green housing colour is a visual identifier on a populated board, not a functional spec, but it helps when you're tracing circuits in a dense panel.","metaTitle":"TE Connectivity 1546551-2 Buchanan Terminal Block","metaDescription":"TE Connectivity Buchanan 1546551-2 terminal block, 2 positions, 3.50mm pitch, 12 A, 300 V, screw rising cage clamp, through hole, green housing.","metaKeywords":null},"attributes":{"series":"Buchanan","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors","Wire-to-Board Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Color":"Green","Pitch":"0.138\\\" (3.50mm)","Series":"Buchanan","Current":"12 A","Package":"Bulk","Voltage":"300 V","Features":"-","Wire Gauge":"16-28 AWG","Screw Thread":"-","Mounting Type":"Through Hole","Product Status":"Active","Torque - Screw":"-","lifecycle_stage":"unknown","Housing Material":"Polyamide (PA66), Nylon 6/6","Number of Levels":"1","Wire Termination":"Screw - Rising Cage Clamp","Mating Orientation":"Horizontal with Board","Base Product Number":"1546551","Positions Per Level":"2","Operating Temperature":"-40°C ~ 110°C","Clamp Material - Plating":"Copper Alloy - Nickel Plated","Screw Material - Plating":"Copper Alloy - Nickel Plated","Contact Material - Plating":"Copper Alloy - Tin Plated"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8800","priceTiers":[{"qty":1,"price":"$0.88000","currency":"USD"},{"qty":10,"price":"$0.84200","currency":"USD"},{"qty":25,"price":"$0.80520","currency":"USD"},{"qty":50,"price":"$0.79400","currency":"USD"},{"qty":100,"price":"$0.69380","currency":"USD"},{"qty":250,"price":"$0.66788","currency":"USD"},{"qty":500,"price":"$0.63076","currency":"USD"},{"qty":1000,"price":"$0.54542","currency":"USD"},{"qty":5000,"price":"$0.46750","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1546551-2/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and current rating of 1546551-2?","answer":"The pitch is 3.50 mm (0.138 inches) and the current rating is 12 A per position at 300 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1546551-2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/1546551-2 when reusing this data.
