5PCS SIP-1A05 Reed Switch Relay 5V DC 4-Pin 1A Module by JESSINIE

Description

Product Overview

The 5PCS SIP 1A05 Reed Switch Relay is engineered to meet the demanding requirements of modern industrial automation and control systems. Each unit operates on a stable 5 V DC power supply, delivering a consistent 1 A current rating that ensures reliable actuation across a broad range of low‑power applications. The internal reed switch is housed within a sealed glass envelope, providing a resistance of 450‑550 Ω when the contacts are open, which translates to predictable electrical behavior and minimal leakage current.

Constructed from high‑grade copper alloy contacts and a robust FR‑4 printed circuit board, the relay offers excellent durability against vibration, temperature fluctuations, and environmental contaminants. The four‑pin configuration—comprising power, ground, signal input, and signal output—facilitates straightforward integration into existing wiring harnesses, while the compact footprint (6.93 × 4.61 × 0.24 inches) allows for installation in space‑constrained panels and enclosures. The device is certified for operation up to 36 V, providing flexibility for a variety of voltage regimes commonly encountered in industrial settings.

Manufactured by JESSINIE, a reputable supplier known for stringent quality control processes, each relay undergoes rigorous testing for contact bounce, response time, and long‑term endurance. The product’s best‑seller rank within the Reed Switches sub‑category reflects its popularity among engineers seeking a balance of performance, cost‑effectiveness, and reliability.

Usage

This reed switch relay excels in environments where magnetic actuation is preferred over mechanical movement, such as in proximity sensing, safety interlocks, and position monitoring. Its normally‑open (NO) configuration means the circuit remains open until a magnetic field is applied, making it ideal for applications that require a clean, noise‑free transition, like conveyor belt start‑stop controls, robotic arm limit switches, and HVAC system monitoring.

Engineers designing low‑power control panels will appreciate the relay’s low coil current draw, which reduces overall system power consumption and heat generation. The 5 V DC operating voltage aligns with common microcontroller and PLC power supplies, simplifying the design of embedded control circuits. Additionally, the relay’s ability to handle up to 36 V expands its suitability for mixed‑voltage environments, such as those found in renewable energy installations, battery management systems, and automotive diagnostics.

Installation is straightforward: connect the coil pins to the 5 V source and ground, then route the signal pins to the target circuit. The sealed glass envelope protects the reed contacts from dust, moisture, and corrosive gases, ensuring consistent performance even in harsh industrial atmospheres. Whether mounted on a DIN rail, panel board, or custom enclosure, the relay’s compact size and robust construction make it a versatile component for a wide array of automation projects.

Why Choose Us

Choosing the 5PCS SIP 1A05 Reed Switch Relay from JESSINIE means selecting a component backed by a legacy of precision engineering and rigorous testing.

FAQ

What voltage range can the relay safely operate within?

The relay is designed for a nominal 5 V DC supply for the coil, but it can handle signal voltages up to 36 V, making it suitable for a variety of control voltage levels.

Is the relay compatible with standard PLC and microcontroller I/O levels?

Yes, the 5 V coil voltage aligns with common PLC, Arduino, and Raspberry Pi logic levels, allowing direct interfacing without additional level‑shifting circuitry.

How does the normally‑open configuration affect circuit behavior?

In a normally‑open (NO) setup, the contacts remain open until a magnetic field is applied, ensuring that the circuit only closes when the intended magnetic trigger is present, which reduces false activations.

Can the relay be used in harsh environmental conditions?

The sealed glass envelope and robust FR‑4 board provide resistance to dust, moisture, and temperature extremes, making the relay suitable for industrial environments, including factories, outdoor installations, and automotive applications.

What warranty or after‑sales support does JESSINIE offer?

JESSINIE provides a one‑year limited warranty covering manufacturing defects, along with technical assistance, replacement parts, and custom configuration support to ensure long‑term satisfaction.
