59040 Press-Fit Firecracker Reed Sensor + 57040 Actuator
Description
The 59040 Press-Fit Firecracker Reed Sensor is a small, cylindrical reed sensor
31.0mm (L) x 10.7mm (Dia.) (1.22” x 0.420”) with a choice of normally open,
normally closed or change-over contacts. It is capable of switching up to 300Vdc
at 10W and available with a range of sensitivity, cable length and connector
options. It is well suited for position and limit sensing, security, level sensing and
linear actuator applications. It functions best with the 57040 actuator.
Reed Sensors
Features
• Magnetically-operated proximity
sensor
• Cylindrical capsule with retaining
ribs
• Operates through non-ferrous
materials such as wood, plastic or
aluminum
• Hermetically sealed contacts
• Options of normally open, normally
closed or single-pole-double-throw
• Customer-defined sensitivity
• Custom cable length and connector
options available
Benefits
• Ribs on capsule compress when
inserted into a mounting hole and
provide retaining force, allowing
simple and secure press-fit
installation
• Quick and easy press-fit installation
that requires no screws, brackets,
nor glue.
• Well suited for usage in high-
moisture and contaminated
environments
• Non-contact solution, aesthetically
more appealing than push-button or
lever mechanical-type switches
• Ideal for battery-powered
applications as the contacts do not
draw power when in the non-
activated state
• Reed contacts last for millions of
operating cycles under micro-
controller voltage and current logic-
level loads
Applications
• Position and limit sensing
• Security
• Level sensing
• Linear actuators

Note: The 57040 Actuator is sold separately.
Notes:
1. The 59040 Sensor and 57040 Actuator are designed to fit into a drill size hole of 9.5mm
(0.374") diameter.
2. Not recommended to be mounted within ferrous metal materials, these activate distance
will decrease significantly.

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 sensitivity options and a normally open high-voltage switch option are available.

Note:
1. Pull-In AT Range: These AT values are the bare reed switch AT before modification.
2. The activate distance is an average value for the final sensor assembly.
3. Not recommended to be mounted within/near ferrous metal materials; if doing so, these
activate distances will decrease significantly.
