Tesnaao 4 PCS Car 12V 40A 5 Pin Relay, JD1914 Waterproof Housing and Alloy Contact Relay, Normally Open Normally Closed Plug-in Changeover Relay with Plastic Handle, Universal for Cars

The relay's working principle is as follows: when the 5-pin relay coil is energized, the mechanical part of the contact is attracted to complete the switch state, allowing the external circuit to be connected or disconnected. This makes the relay suitable for use in automotive lighting systems, motors, and other applications.

Product Specifications: The relay has 5 pins: 85 (control line power input terminal), 86 (control line ground terminal), 87 (normally closed pin), 87a (normally open pin), and 30 (total power supply enter). It features both normally open and normally closed terminals, providing better circuit control.

Silver Alloy Contacts: The relay uses silver alloy contacts, which have stronger conductivity and a longer service life. The all-copper coil ensures more reliable and precise suction, with lower temperature rise, stronger suction, and more stable performance.

Flame-retardant Shell: The relay's shell is made of waterproof and flame-retardant plastic material, with good thickness and smoothness. It is resistant to high temperatures, allowing the relay to cope with various environmental challenges and ensuring safer use.

Packing List: The package includes 4 x 5-pin relays, each equipped with plastic mounting tabs for easy installation. The simple plug-in design allows for plug-and-play functionality. If you have any questions regarding the use of the product, you can contact the manufacturer directly, and they will solve the problem for you within 24 hours on weekdays.
