Littelfuse SD Series Flange Latching Relay 1 NO/1 NC Screw Terminal -50°C to 125°C 880107

Littelfuse 880107 flange Latching Relay is a high-amp SD series relay designed for remote disconnect switching with a 1 NO/1 NC contact configuration and flange mounting type. This relay operates over a wide temperature range from -50°C to 125°C, making it suitable for demanding industrial and automotive environments such as heavy machinery, vehicles with hazardous loads, and high ambient temperature applications.

The bi-stable internal mechanism allows the relay to consume no current in either On or Off state, enhancing energy efficiency. It supports multiple emergency stop off switch controls and uses small control wires, reducing the need for heavy copper cabling. The device features screw terminals for reliable electrical connection and is rated IP66/IP69K for ingress protection, allowing operation in environments subject to dust and water jets.

Certified to SAE J1171 ignition protection and ISO 8846 for hazardous load applications, the relay can be installed within battery boxes or vehicles requiring such safety standards. It also includes auxiliary relay contacts for alternator field disconnect and additional vehicle system control, and a dedicated 24-hour output for tachograph and keep-alive functions which ensures continuous monitoring and control.

This relay is ideal for industrial, automotive, heavy equipment, and construction applications where reliable high-current switching and remote disconnect capability are critical. The flange mounting design facilitates easy and secure installation in various equipment.

Auxiliary relay contacts include normally open and closed configurations for system control. Bi-stable mechanism draws zero current in On and Off states enhancing efficiency. Ingress rating IP66/IP69K protects against dust and powerful water jets.

Wide operating temperature range from -50°C to +125°C for extreme environment durability. Supports emergency stop controls using small control cables for ease of installation. Conforms to SAE J1171 ignition protection and ISO 8846 standards for hazardous environments.

Includes a 24-hour output for tachograph and keep-alive functions. Explore more high-quality relays and related electronic components in the Electronics & Electricals category at EnvMart for diverse industrial and automotive needs.
