TE Connectivity Contact Configuration Oeg Te Connectivity 1721081-9.

The 28AC7454 is a miniature PCB relay from the PCJ series, featuring a single pole, normally open (1 form A) contact configuration. It is rated for a maximum switching voltage of 250VAC and can handle currents of 3A or 5A, depending on the version. The relay operates with a sensitive coil requiring only 200mW of power, making it suitable for applications in home appliances and other general-purpose uses. This relay is RoHS compliant and meets various safety standards, including VDE, UL, and CSA approvals. It has a mechanical endurance of over 10 million operations and an electrical endurance of 100,000 operations at rated load. The coil voltage range is from 3 to 24VDC, with a recommended minimum contact load of 100mA at 5VDC. The relay also features robust insulation properties, with dielectric strength ratings of 750V between open contacts and 4000V between contact and coil. The product is designed for ambient temperatures ranging from -40°C to 85°C, with a wash-tight version available for more demanding environments. The relay's compact size and through-hole mounting make it easy to integrate into various electronic designs.
