The EFMT723-M159 is a 5-Pin, 6 Amp, Self-Latching Relay manufactured by Teledyne. It features a plug-in design, IR/UL approval, and 5kV dielectric strength. It is ideally suited for low-level switching and control applications in applications including HVAC, fire safety, power supply, security, and home theater systems. The relay utilizes a Negative Impedance Temperature Coefficient (NITC) for fast and reliable latching action (i.e. the relay will spontaneously and immediately open after latching). The relay can be used in a variety of configurations, and is suitable for use in potting boxes and mounted to heatsinks.
