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.
Note: The 57040 Actuator is sold separately.

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

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.
Applications
• Position and limit sensing
• Security
• Level sensing
• Linear actuators
