New Original Finder 90.03.SMA DIN Rail Relay Socket<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
Finder part\u2011number 90.03.SMA is an original Italy\u2011made relay socket designed to match Finder 60.13 series 11\u2011pin plug\u2011in power relays. It serves as the connecting base between the relay and control\u2011circuit wiring. This socket supports DIN\u2011rail mounting and screw\u2011terminal wiring, widely applied inside control cabinets, automated assembly lines, packaging machines, pump\u2011control panels and workshop electrical systems. The housing is built with high\u2011strength flame\u2011retardant PA66 plastic conforming to UL94\u2011V0 grade. Its metal contact clips are tin\u2011plated brass to achieve stable electrical conductivity and anti\u2011oxidation performance. This socket complies with CE, UL and RoHS requirements for global industrial\u2011control applications. The SMA suffix stands for screw\u2011clamp terminal structure and built\u2011in metal retaining clip to lock relays firmly against vibration.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Reliable electrical connection: Tin\u2011plated brass internal contact pieces closely engage with relay pins to transmit control\u2011circuit signals and load\u2011current steadily. Screw terminals accept stranded wires or solid\u2011core wires for field wiring.<\/li>\n
  2. Firm fixing structure: Integrated metal retention clip locks the plugged\u2011in relay tightly. It prevents relay loosening caused by equipment vibration during long\u2011time running.<\/li>\n
  3. Standard DIN\u2011rail installation: The rear buckle fits 35 mm standard DIN rail. Users can also install it on flat panels by reserved mounting holes.<\/li>\n
  4. Convenient maintenance design: The relay can be pulled out directly without disconnecting field\u2011wires when replacement or inspection is needed, which greatly shortens equipment\u2011downtime.<\/li>\n
  5. Compatibility for auxiliary modules: It reserves installation space for Finder\u201186\u2011series timer modules and surge\u2011suppression modules mounted on the top of relays.<\/li>\n
  6. Clear terminal marking: Terminal numbers are printed on the socket housing for correct wiring and troubleshooting during commissioning.<\/li>\n<\/ol>\n<\/div>\n
    \n

    3. Technical Characteristics<\/h2>\n<\/div>\n

        \n

        6. Application Notes<\/h2>\n<\/div>\n
        \n
          \n
        1. Do not exceed the maximum rated\u2011current of 10 A, otherwise terminal over\u2011heating will appear and cause potential fire hazards.<\/li>\n
        2. Fasten terminal screws with recommended torque; overly loose wires lead to heating while excessive torque may damage internal thread.<\/li>\n
        3. Only match original Finder\u201160.13\u2011series relays; mismatched relay pins will result in poor contact.<\/li>\n
        4. Keep this socket away from cutting fluid, oil mist and corrosive gas. Select fully enclosed sockets if working environment is harsh.<\/li>\n
        5. Confirm terminal\u2011number marking before wiring to avoid wrong\u2011connection that burns out relays or control\u2011system components.<\/li>\n<\/ol>\n<\/div>","protected":false},"excerpt":{"rendered":"
