KSK-1A85 Series Reed Switches

Product catalog summary

Overview: The KSK-1A85 Series Reed Switches are designed for high power and high voltage applications, suitable for use in position sensors, valve detection, and level sensors across various markets including automotive, white goods, and HVAC.

Specifications:

Contact Data: Rated power is 100 W, with a maximum switching voltage of 1000 V and a maximum switching current of 1.0 A. The carry current is capped at 2.5 A, and contact resistance is 150 mOhm.
Environmental Data: The switches can withstand shock resistance up to 50 g and vibration resistance up to 20 g. They operate within a temperature range of -40 to 130 °C and can be stored between -55 to 130 °C. The maximum soldering temperature is 260 °C for 5 seconds.
Physical Dimensions: The overall length is 55.4 mm, with a glass length of 21.0 mm, glass diameter of 2.75 mm, and lead diameter of 0.6 mm.

Contact Forms: The datasheet describes various contact forms including Form A (Normally Open), Form B (Normally Closed), Form C (Changeover), and Form E (Bistable Contact).

Handling & Assembly Instructions: Proper lead clamping or heat sinking techniques are recommended to prevent mechanical and heat stress. Mechanical shock from dropping can alter magnetic sensitivity or damage the sensor. Modifying switch leads will also affect magnetic sensitivity.

Life Test Data: The life expectancy of the reed switches decreases with increased load. The document provides a graph showing the typical number of operations under different load conditions.

Note: The datasheet includes a disclaimer about potential technical inaccuracies and advises consulting the product datasheet for more specific information.
