## - 59010 Sub Miniature Firecr ~~acker Reed Sensor + 57020 Actuator~~ 

## **Description** 

The 59010 Firecracker Reed Sensor is a sub-miniature cylindrical reed sensor 9.0mm L x 3.0mm Dia. (0.354” x 0.118”) with a normally open contact. It is capable of switching up to 170Vdc at 10W and has cable length and connector options. It functions best with the 57020-000 actuator. 

**Note: The 57020 Actuator is sold separately.** 

## **Features** 

- Magnetically operated proximity sensor 

- Compact size requires only 3mm diameter hole 

- Hermetically sealed contacts 

- Custom cable length and connector options available 

## **Benefits** 

## **Dimensions**

- Well suited for usage in highmoisture and contaminated environments 

- Non-contact solution, aesthetically more appealing than push-button or lever mechanical-type switches 

- Simple installation and adjustment 

- No standby power requirement 

## **Applications** 

- Position and Limit Sensing 

- Security System Switch 

- 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 

- Level Sensing 

- 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. 

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.
