Description
Product Overview
The Tnisesm CAHK19F‑8P‑9V is a high‑quality PCB‑mount power relay engineered for precise, automatic circuit control. Housed in a compact 2 × 1 × 1.4 cm sealed enclosure, the relay features a 9 V DC coil, silver‑plated contacts, and a dual‑pole, double‑throw (2NO / 2NC) configuration. It supports a maximum switching current of 2 A and a contact rating of 1 A at 125 VAC or 2 A at 30 VDC, making it suitable for low‑voltage automotive and electronic projects. The relay’s PCB mount design simplifies soldering and saves valuable board space, while the automatic operation mode ensures reliable activation without manual intervention. Built to automotive standards, it carries a best‑seller rank in the power relay category and has earned a 4.7‑star rating from over 40 verified customers.
Usage
Designed for automotive replacement accessories, the relay excels in controlling lights, fans, pumps, and auxiliary devices in cars, trucks, and motorcycles. It is equally effective in hobbyist and DIY electronics, such as robotics, home automation, and custom control panels where a compact, reliable switching solution is required. Install the relay on a printed circuit board using its standard 8‑pin layout, connect the 9 V coil to a control signal, and route the load through the 2NO and 2NC contacts. The sealed construction protects against moisture, dust, and vibration, ensuring consistent performance in harsh environments.

FAQ
What voltage should I use for the coil?
The relay is designed for a 9 V DC coil voltage. Supplying the specified voltage ensures proper magnetic actuation and reliable switching.
Can this relay handle inductive loads?
Yes, the relay can switch inductive loads such as solenoids and small motors, provided the load does not exceed the 2 A switching current rating and appropriate flyback diodes are used to protect the contacts.
Is the relay suitable for 12 V automotive systems?
While the coil operates at 9 V, the contacts can switch 12 V loads up to the rated current. Ensure the control circuit supplies the correct 9 V to the coil for activation.
How do I mount the relay on a PCB?
Place the relay on the board using its 8‑pin footprint, align the pins with the solder pads, and reflow solder. The low‑profile design fits within tight spaces.
What warranty does Tnisesm provide?
Each relay comes with a 1‑year limited warranty covering manufacturing defects. Contact our support team for replacement or troubleshooting assistance.
