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 200Vdc at 10W. The 59022 Firecracker Reed Sensor is available with a range of sensitivity and cable length options. It functions best with the 57022 actuator. Note: The 57022 Actuator is sold separately. Features • Magnetically-operated proximity sensor • Hermetically sealed contacts • Operates through non-ferrous materials such as wood, plastic or aluminum Agency Approvals Agency • Options of normally open, normally closed or single-pole-double-throw • Customer-defined sensitivity option • Custom cable length and connector options available Agency File Number Benefits E61760 • 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 Note: Contact Littelfuse for specific agency approval ratings. Dimensions Dimensions in mm (inch) • 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 Applications A B A Nom.

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.
