Datasheet

C&K Components offers a magnetic detect switch designed specifically for use in telecom and enclosure applications. The miniature, surface mount RS Series switches feature a magnetic reed sensor with an omnipolar orientation, allowing it to be operated with either pole of the magnet.

Magnetic switches are typically implemented in the cabinets of rack and panel systems, with access to the fan, server and daughter card via a door or latch. These magnetic detect switches are employed to sense when the cabinet doors are closed, which in turn signals the fan to begin operating, said David Webber, director of product management for C&K Components. The RS Series magnetic detects are particularly suitable for telecom and enclosure applications because of their miniature size, lifespan to 1,000,000 cycles, and rugged design, which allows them to withstand cabinet door slams and misalignment.

Along with telecom and enclosure applications, the RS Series detect switches are also being implemented in consumer electronics, computers, medical devices, factory automation and security equipment.

Available with top or side actuation, the normally-open RS Series magnetic detects feature a contact rating of 5.0VA, with a maximum switching current of 0.35A and a maximum carrying current of 0.5A. Maximum contact resistance is 200m? initial, and operating temperature ranges from -40°C and +140°C. The RoHS compliant and compatible detect switches are available with either gullwing or J-lead terminations, are pick-and-place compatible and available in tape and reel packaging.
