Latching Relay
NCR Industrial's Latching Relay offers several advantages:
●Low power consumption: Once the relay contacts have switched, only a low amount of energy needs to be maintained.
●High stability: the final switching state is maintained even when the power supply is interrupted.
●Long service life: Reduced wear and tear on the coil and longer service life due to energisation only during state changes.
●Widely applicable: Widely used in smart home, industrial control, communication equipment and other fields.
●High Reliability: Vibration and shock resistance ensures reliable operation in harsh environments.
These advantages make NCR Industrial's suction relays an indispensable key component in a wide range of applications.
FAQ
What is the purpose of a latching relay?
A latching relay, also known as a bistable relay, is designed to maintain its position of contacts even after the actuating force is removed. Here are the primary purposes and benefits of a latching relay:
1.Energy Efficiency: After the relay has been set to a particular state (either latched or unlatched), it does not require continuous power to maintain that state. This significantly reduces energy consumption, making it ideal for battery-powered or energy-sensitive applications.
2.State Retention: Latching relays retain their last state even in the event of a power failure. This means once they are set or reset, they will stay in that position until an opposite actuation force is applied. This feature is crucial in applications where it is essential to maintain the last command state regardless of power interruptions.
3.Reduced Heating: Since they do not require constant power to maintain their state, latching relays generate less heat compared to non-latching relays. This can be beneficial in environments where minimal heat generation is needed.
4.Dual-Coil Designs: Many latching relays have a dual-coil design where one coil sets the relay and the other resets it. This allows precise control over the relay’s state.
5.Applications: Latching relays are widely used in various applications including:
○Home Automation: Control of lighting, window blinds, and other smart home devices.
○Industrial Control Systems: Handling devices and machinery that require state retention without continuous power.
○Telecommunications: Switching circuits in communication networks.
○Memory Storage Systems: Maintaining states in devices requiring persistent memory.
○Alarm Systems: Ensuring that alarm states are retained without the need for continuous power.
How to reset a latching relay?
For an NRL709N relay.
Reset Coil: Check the datasheet for the reset coil connection.
Voltage: If the reset coil requires a 24V DC signal, make sure your power supply meets that specification.
Apply Signal: Connect a 24V DC power supply to the reset coil terminals and apply voltage momentarily.
Check Status: Use a multimeter to verify that the relay contacts have moved to the default (open) position.
What does a latching switch do?
A latching switch is a type of switch that maintains its position after being actuated. Here’s a detailed explanation of what a latching switch does and its various applications:
Functionality:
State Retention: Once pressed or actuated, a latching switch changes its state (e.g., from off to on) and remains in that state without the need for continuous pressure or power. It stays latched in the new state until it is manually toggled back.
Mechanism: Latching switches typically use a mechanical mechanism (such as a toggle, rocker, or push button) that locks the switch in place.
Types:
Toggle Switches: Changes position up or down to latch in the on or off state.
Push Button Switches: Actuated by pressing; remains in the pressed position until pressed again to release.
Rocker Switches: Flips between positions, staying in the selected state.
