Reed Sensors Firecracker > 59022 59022 Firecracker Reed Sensor + 57022 Actuator Description The 59022 Firecracker Reed Sensor is a small cylindrical reed sensor, 25.4mm (L) x 5.80mm (Dia.) (1.00” x 0.228”), with a choice of normally open, normally closed or change-over contacts. It is capable of switching up to 300Vdc at 10W. The 59022 Firecracker Reed Sensor is available with a range of sensitivity and cable length options. It is ideally suited for position and limit sensing, security, level sensing, and linear actuator applications. It functions best with the 57022 actuator. Note: The 57022 Actuator is sold separately. Features Agency Approvals Agency Agency File Number • 25.4mm x 5.80mm form factor • Magnetically-operated proximity sensor • Hermetically sealed contacts • Operates through non-ferrous materials such as wood, plastic or aluminum • Options of normally open, normally closed or single-pole-double-throw • Customer-defined sensitivity • Custom cable length and connector options available E61760 (TBD) Benefits • Fits nicely into small confined spaces • Quick and easy to install • Well suited for usage in highmoisture and contaminated environments • Non-contact solution, aesthetically more appealing than push-button or lever mechanical-type switches Dimensions Dimensions in mm (inch) A • Ideal for battery-powered applications as the contacts do not draw power when in the nonactivated state • Reed contacts last for millions of operating cycles under microcontroller logic-level loads A B A Max.

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.
