KSK-1A33 Series Reed Switches

Product catalog summary

Overview: The KSK-1A33 Series Reed Switches are designed for high power, high voltage, and high current applications. They are suitable for use in batteries, motors, lamps, relays, and other devices across various markets including test & measurement, automotive, and medical sectors.

Specifications:

Contact Data: Rated power is 50 W, with a maximum switching voltage of 250 V and a maximum switching current of 3.0 A. The carry current is capped at 5.0 A, and contact resistance is 80 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 79.0 mm, with a glass length of 52.0 mm, a glass diameter of 5.4 mm, and a lead diameter of 0.5 mm.

Contact Forms:

Form A: Normally Open Contacts (SPST)
Form B: Normally Closed Contacts (SPST)
Form C: Changeover (SPDT)
Form E: Bistable Contact (Latching Type)

Handling & Assembly Instructions:

Use proper lead clamping or heat sinking techniques to prevent mechanical and heat stress during soldering and welding.
Avoid mechanical shock from dropping the sensor as it may alter magnetic sensitivity or damage the sensor.
Modifying switch leads will change its magnetic sensitivity.

Note: The datasheet may contain inaccuracies or typographical errors. For the most current specifications and product details, contact the nearest sales office.
