20 pieces of SJS112DM 4pin relays, each rated for 5A switching. Compact, reliable signal relays supplied in a bulk lot for prototyping, repairs, and small production runs. Key benefits Bulk pack of 20: keeps spare parts on hand, reduces reordering and downtime. Clear 4pin footprint and compact form factor: convenient for many common PCB designs and relay sockets. 5A contact rating: suitable for switching small loads and signallevel power where a 5 amp limit is required. Modelspecific replacement: SJS112DM ensures consistent fit and performance when matching original equipment. Key attributes Model: SJS112DM Quantity: 20 pieces per lot Pin count: 4 pins Contact rating: 5A Form factor: compact 4pin relay suitable for typical relay footprints How this relay solves common problems Easy replacement: swap a failed relay without redesigning the PCB; SJS112DM matches common 4pin layouts for quick replacement. Costeffective sourcing: buying a 20piece lot lowers unit cost and ensures you have spares during assembly or maintenance. Appropriate for lowtomoderate current switching: use where loads do not exceed the 5A contact rating to avoid overstressing the relay. Typical applications Electronics prototyping and maker projects: control LEDs, small motors, fans, or modules from microcontrollers and driver circuits while keeping wiring tidy and repeatable. Home automation and lighting control: switch lighting circuits, relays for timers, or control modules where load currents are within the 5A specification. and maintenance: direct replacement for equipment that uses the SJS112DM relay or other devices that accept a 4pin, 5A relay. Installation and use notes Confirm the relay's contact rating (5A) is adequate for your load; avoid exceeding the rated current. Verify pinout and mounting footprint before soldering or inserting into a socket. Observe correct wiring and testing procedures; disconnect power before installing or replacing relays. Ordering information Supplied as a lot of 20 identical SJS112DM relays (4 pins, 5A). Ideal for batch projects, service kits, and smallrun manufacturing where consistent parts are required.
