This Omron PF083A-E general purpose socket has screw terminal connections, finger-safe construction, mounts to a track, and is used with MKS2 series relays. This socket has two contact poles and a maximum carry current of 10 amp. The carry current is the maximum amount of current that can be continuously applied without opening or closing the contacts. It has screw terminals for connecting to MKS2 series relays and is constructed to make it difficult for a human finger to touch the current-carrying parts. This general purpose socket mounts to a track and complies with the Restriction of Hazardous Material (RoHS) directive, is recognized by Underwriter's Laboratories (UL) for safety and certified by Canadian Standards Association (CSA) for quality assurance.
Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
Omron manufactures and distributes electronic components, equipment, and systems for industrial automation. The company, founded in 1933, is headquartered in Kyoto, Japan.
