59010 Sub-Miniature Firecracker 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
Actuator
• 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

Nom.
• 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

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.
