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

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.
