SED Handsets are robust and assembled from high quality components for exceptional durability in harsh environments. They are generally used with mobile radio products, PA or intercom equipment. They consist of a receiver (speaker), a transmitter (microphone) and can include pre amplifiers, a push-to-talk (PTT), push-to-mute (PTM) or push-to-call buttons. Handsets are available in a variety of formats and can be purchased with or without a cradle.
The cradle holds the radio or telephone handset in vehicles or in stationary locations. A cradle maybe be passive with no moving parts other than a retaining clip to keep the handset in place or it may contain a hook switch to provide a variety of electrical functions for the handset and/or radio connected to it. A terminal strip provides a termination point for wiring or it may be equipped with an adapter cord or connector for connection to a host device.
SED cradles are high-quality and accept a variety of handsets. Assemblies are completely wired and will only require connection to the radio PTT/Mic Connector and splicing into the external speaker wiring.
