SM-S-112D SANYOU Pole Relay

Review SANYOU Original New Sealed Type Pole 12v Dc Relay 16a 250vac

The Sanyou SM-S-112D is a 12V DC coil operated, single-pole, double-throw (SPDT) relay with a switching capacity of 16Amperes at a maximum operating voltage of 250 Volts AC. This versatile relay is designed to provide reliable and efficient electrical switching in various applications.

The SM-S-112D has a compact size, measuring just 30mm x 22mm x 14mm, while offering a contact rating of 10,000 make and break cycles. This makes it an excellent choice for projects where space is at a premium, and repeated switching is required.

The unit features a gold-plated silver contact system that ensures reliable electrical conductivity, reducing the risk of contact bounce and minimizing electrical resistance. The silver-plated contacts are known for their excellent conductivity, corrosion resistance, and reduced contact resistance, contributing to a long contact life and improved switching performance.

The SM-S-112D comes with a form A, normally open (NO) contact configuration. This means that when the coil is not energized, no electrical connection is established between the contacts. Once the coil is activated, the contacts in the relay make a connection to the external circuits, allowing electricity to pass through.

The relay features a screw terminal design for easy and secure wiring. The screw terminals accept wires up to 2.5mm2, ensuring a strong connection to the contacts, avoiding the risk of wires coming loose during operation.

The SM-S-112D operates at a coil current of 187mA and a coil resistance of 40 Ohms, which results in an attractive operating voltage drop of around 6.7V when the coil is energized. A built-in diode across the coil provides reverse voltage protection, which safeguards the relay against inductive load prikethrough from inductive loads such as motors or solenoids.

With a maximum voltage drop at the switch contacts of 50mV, the Sanyou SM-S-112D is suitable for a wide array of applications, including lighting control, automation systems, industrial machinery and equipment control, and various other projects where reliable electrical switching is essential.

This solid-state relay provides excellent switching performance, durability, and reliability, backed by Sanyou's commitment to quality and customer satisfaction. With its extensive electrical specifications and robust design, the SM-S-112D is an excellent investment for electronic enthusiasts, engineers, or anyone seeking an efficient and reliable solution for reliable electrical switching applications.

1. High Current Capacity: This relay can handle a large current of up to 16 Amperes, making it suitable for various applications where high current is required.

2. Wide Voltage Range: The relay can operate at a voltage as high as 250V AC, making it versatile for use in different applications.

3. Pole-mounting: The pole-mounted design allows for easy installation and wiring, making it an excellent choice for automation projects, machinery control, or OEM applications.

4. Robust Design: Sanyo Denki is known for its high-quality products, and this relay is no exception. It is built to last, ensuring reliable operation for extended periods.

5. Cost-Effective: Compared to other relays in the same class, the SM-S-112D is relatively affordable.

1. Manual Operated: This relay is a manual-operated type, meaning it requires external sources to activate the contacts. Manual-operated relays may not be the best option for applications requiring rapid switching or high-frequency switching.

2. Limited Switching Duty Cycle: The relay's switching duty cycle is limited to 15 minutes in a continuous operation mode. It might not be the best choice for applications requiring long duty cycles.

3. Size: The pole-mounted design makes the relay larger than some other relays of similar rating. Make sure you have enough space for installation before purchasing.

4. Requires External Power Source: Since it's a 12V DC relay, it needs a separate power source for operation.

The Sanyo Denki SM-S-112D relay is a robust, cost-effective option for various applications requiring a high current and voltage rating. Its pole-mounted design allows for easy installation and simple wiring. However, it may not be the best choice for applications requiring rapid switching, high-frequency switching, or long duty cycles.

If you are looking for a durable, pole-mounted, high-current, and high-voltage relay for your automation project, machinery control, or OEM application, the Sanyo Denki SM-S-112D is an excellent option. Its wide voltage range and cost-effectiveness make it a valuable investment for your projects. However, if rapid switching or long duty cycles are essential for your project, consider looking into other types of relays, such as solid-state relays or opto-isolated relays.
