3PDT Electromagnetic Relay

Electromagnetic relay is a kind of electronic control device, 3PDT electromagnetic relay is a series of electromagnetic relays. ATO industrial automation supplier offers high quality 3 pole double throw electromagnetic relay with 11-pin. All the contacts of the electromagnetic relay are made of silver alloy material, which has super conductive property, making the service life longer. Electromagnetic control relay often used in automation system, receiver, sound equipment and household appliance. ATO as a vendor can also provide customized services.

3PDT electromagnetic relay

Features:

  1. High reliability. The 3 pole double throw electromagnetic relay has no mechanical parts, and the contact function is completed by solid devices. Because there are no moving parts, it can work in the environment of high impact and vibration.
  2. High sensitivity, good electromagnetic compatibility. The electromagnetic relay has a wide input voltage range, low drive power, and can be compatible with most logic ics without the need for buffers or drivers. Same thing as DPDT electromagnetic relay.
  3. Capable of fast conversion. Electromagnetic relays use solid state devices, so the switching speed can be from a few milliseconds to a few microseconds.
  4. Low electromagnetic interference. The electromagnetic relay does not touch the ignition arc, thus reducing the electromagnetic interference.

Tips: How to Select 3PDT Electromagnetic Relay?

  1. Input Signal. Select electromagnetic, temperature, time or photoelectric relays by judging whether input signals are electricity, temperature, time or photo signals.
  2. Load Condition. Configurations and groups of contacts shall be determined according to actual conditions of controlled circuit. It is very important to determine parameters according to load capacity and load nature.
  3. Working Environment. Working environment mainly refers to temperature (maximum and minimum temperature), humidity (maximum relative humidity in -40℃), low pressure (it is unnecessary for places with an elevation of lower than 1,000 meters to consider the factor), oscillation and impact. In addition, service environment involves requirements for packaging mode, installation mode, shape, dimensions, and insulation performance etc.
