Technical content

Features

  • Magnetically-operated proximity sensor
  • Cylindrical capsule with retaining ribs
  • Operates through non-ferrous materials such as wood, plastic or aluminum
  • Hermetically sealed contacts
  • Options of normally open, normally closed or single-pole-double-throw
  • Customer-defined sensitivity
  • Custom cable length and connector options available Benefits
  • Ribs on capsule compress when inserted into a mounting hole and provide retaining force, allowing simple and secure press-fit installation
  • Quick and easy press-fit installation that requires no screws, brackets, nor glue.
  • Well suited for usage in high- moisture and contaminated environments
  • Non-contact solution, aesthetically more appealing than push-button or lever mechanical-type switches
  • Ideal for battery-powered applications as the contacts do not draw power when in the non- activated state
  • Reed contacts last for millions of operating cycles under micro- controller voltage and current logic- level loads

Applications

  • Position and limit sensing
  • Security
  • Level sensing
  • Linear actuators Dimensions Dimensions in mm (inch) Sensor Actuator Firecracker > 59040 Note: The 57040 Actuator is sold separately. Notes: 1. The 59040 Sensor and 57040 Actuator are designed to fit into a drill size hole of 9.5mm (0.374") diameter. 2. Not recommended to be mounted within ferrous metal materials, these activate distance will decrease significantly. 8.46±0.25 (.333±.01) Actuator Sensor 10.70 ±0.25 (.42± .01) 10.70 ±0.25 (.42 ±.01) 31.00±0.25 (1.22±.01) 300 (11.81) 8.46±0.25 (.333±.01) 31.00±0.25 (1.22±.01)

Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information. 2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and AN107 for details. 3. Breakdown Voltage - per MIL-STD-202, Method 301. Leakage current is less than 0.1mA for 60 seconds. 4. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load. 5. This resistance value is for 11.81mm wire length. Resistance changes when wire lengthens. 6. Operate (including bounce)/Release Time - per EIA/NARM RS-421-A, diode suppressed coil (Coil II). 7. Shock and Vibration - per EIA/NARM RS-421-A and MIL-STD-202. 8. For custom modifications to the wire length or size, or adding a special connector, please contact Littelfuse. 9. Custom sensitivity options and a normally open high-voltage switch option are available.
