AGN2004H Introduction

AGN2004H is a single-pole, double-throw (SPDT) electromagnetic relay that is very reliable and inexpensive. Panasonic designed and makes this small relay, which is used in systems for measuring and controlling, security, and building automation, among other things.

AGN2004H Features

  • Printed circuit boards with a 5mm pin pitch and a 10mm height can hold many components.
  • The capacity of the switch is 5A at 250VAC or 30VDC.
  • 5VDC or 12VDC coil voltage.
  • Dependent on coil voltage, it uses 200mW or 400mW of power.
  • Between the coil and the contacts, a high dielectric strength of 1500 VAC exists.
  • With a high sensitivity of 140mW, designs that use less energy can be made.
  • Long mechanical life of 10 million operations and 100,000 electrical operations.
  • The construction is sealed, which makes it very resistant to dust and humidity.

One of the best things about the AGN2004H is that it is very reliable and has a long mechanical and electrical life. It can handle dust, humidity, and changes in temperature and humidity. Because of this, it can be used in harsh industrial settings. Also, its small size and ability to be mounted in a high density make it a great choice for applications with limited space.

Cautions for the usage of GN relay


Use latching when conditions involve continuous carrying current.

If you want your coil to work reliably regardless of fluctuations in temperature or load, you should increase the set and reset pulse time to 10 ms or more at the rated coil voltage.

The relay ships in a position called “reset.” Bumping during transit or installation can affect the reset position. So, it’s best to build a circuit where the relay can be initialized (set and reset) as soon as the power is turned on.

How to use an automatic inserting machine safely Set the automatic mounting machine’s chucking pressure of the pick-up mechanism to the pressure shown in Table 1 to keep the relay’s internal functions working.

Guidelines For Signal Relays Usage

Precautions For Coil Input

● Long-term current carrying

A circuit that will carry a current nonstop for a long time without a relay switching on and off. (circuits for emergency lights, alarms, and error inspection that, for example, only turn back when something goes wrong and send out warnings with form B contacts) Continuous, long-term current to the coil will make the insulation and characteristics of the coil worse because the coil will heat up. For these kinds of circuits, please use a magnetic-hold latching relay. If only one stable relay is required, use a sealed relay resistant to environmental deterioration. You should also design a failsafe circuit that considers the possibility of a contact failing or becoming disconnected.

● DC Coil operating power

DC current should flow steadily through the coil. The wave should look like a rectangle. The ripple factor should be less than 5% if it involves a ripple. But check with the actual circuit because the electrical properties may be different. The coil should be given the rated coil voltage, and the set/reset pulse time of a latching type relay is different for each relay; please look at the specifications for each relay.

● Coil connection

When connecting the coils of polarized relays, check the internal connection diagram for the (+,-) polarity of the coils ( Schematic ). If a wrong connection is made, it could lead to unexpected problems, such as too much heat, a fire, or the circuit not working. Don’t apply voltage to both the set coil and the reset coil at the same time.

● Maximum allowable voltage and temperature rise

The coil must be marked with the rated coil voltage for proper use. Note that if a voltage greater than or equal to the maximum continuous voltage is put on the coil, the temperature rise could cause it to burn or its layers to short out. Also, don’t go over the range of temperatures the catalog says can be used.

● When the temperature of the coil rises, the operating voltage shifts (hot start)

In DC relays, if the current is switched off and then on again, the coil temperature rises, raising the operational voltage. It will also behave the same as in a hotter environment. Copper wire’s resistance/temperature relationship is 0.4 % per 1 °C, increasing coil resistance. Hence, the relay must function at a voltage higher than the operational voltage, which grows with resistance. Certainly, polarized relays change much slower.

● Usage, Storage, and Transport Conditions

Whether using, storing, or transporting it, stay out of direct sunlight and keep the temperature, humidity, and pressure normal. Here are the conditions that can be used, stored, or moved.

Temperature: Each relay can handle the temperature range listed in the relay’s specifications. Keep the relays in their tubes when traveling or storing them. the temperature may be outside the range that is allowed. In this case, it’s important to look at the individual requirements. 2) Relative humidity: 5 to 85% The range of humidity changes based on how hot or cold it is. Use between the lines shown on the graph. (The relays set the temperature limit.)

● Condensation

Condensation happens when the ambient temperature drops quickly from a high temperature and high humidity or when the relay or microwave is moved quickly from a low ambient temperature to a high temperature and high humidity. Failures like insulation breaking down, wires coming loose, rust, etc., are caused by condensation.

Panasonic Industry Co., Ltd. doesn’t take responsibility for problems that happen because of condensation. Heat transfer from the equipment to the air may speed up the device’s cooling, and condensation may happen. Please test products in the worst way they will be used in real life. (You should pay extra attention when parts that heat up at high temperatures are close to the device. Also, please remember that there may be condensation inside the device.

● Icing

When the temperature drops below 0 °C, relays can freeze. Ice sticks to things, stop them from working, and stops contact. Failures caused by ice are not Panasonic’s fault. Equipment heat transfer could speed up the cooling of a relay, which could freeze it. Test things in the worst way you can think of.

● Low temperature and low humidity

The plastic will become brittle if the switch is left in an area with low temperature and low humidity for a long time.

● High temperature and high humidity

A sulfide film or an oxide film could form on the contacts if they are stored for long periods of time (including when they are being moved) at high temperatures or high humidity or in an environment with organic gases or sulfide gases. This could stop the contacts from working. Check out the environment where the units will be kept and moved.

● Package

Make sure that the organic gases, effects of moisture, and sulfide gases are kept to a minimum by how the items are packed.
