## 59022 Firecracker Reed Se ~~nsor + 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.**

   - Options of normally open, normally closed or single-pole-double-throw 

- Magnetically-operated proximity sensor 

   - Customer-defined sensitivity option 

- Hermetically sealed contacts 

   - Custom cable length and connector options available 

- Operates through non-ferrous materials such as wood, plastic or aluminum 

## **Benefits** 

   - Ideal for battery-powered applications as the contacts do not draw power when in the nonactivated state 

- Fits nicely into small confined spaces 

- Quick and easy to install 

- Well suited for usage in highactivated state moisture and contaminated • Reed contacts last for millions of environments operating cycles under micro- 

- • Non-contact solution, aesthetically controller logic level loads more appealing than push-button or lever mechanical-type switches 

## **Applications** 

   - Level sensing 

- Position and limit sensing 

- Security 

- Linear actuators

## Notes: 

1. 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 sensitivities and a high voltage switch are options
