Micro Mini Surface Mount Detect Switch From C&K

Many devices are using switches to detect system opening and piracy or position of a mechanism. The difficulty is to find SMD switches able to combine long travel (1.5 mm) and small format (7 x 3.5 mm height 5 mm) for an easy integration.

C&K’s KSU detect series has these characteristics and a multi contact construction. Its metal actuator guarantees an excellent sliding, the rounded tip and the low actuation force (0.7N) allows to operate the switch with a thin strip. An example of this is the presence of the strip in a glucose meter to start the reading.

KSU is available with silver plated contacts and gold contacts for high reliability applications. KSU features a low energy consumption using low switching level at 0.01 mA @ 20mV (gold version) and an operating life of 50 000 cycles.

 

Features/Benefits:

  • 1,5 mm travel
  • SMT tape & reel
  • Top actuated with metal frame
  • Normally open & low current consumption

Typical Applications include:

  • Anti-tampering: metering, network & alarms, payment terminals
  • Anti-theft and pharmaceutical
  • Access controls, exits/openers & closers
  • Charging inlets
  • RFID Tags
