Reed Sensors Firecracker > 59040 59040 Press-Fit Firecracker Reed Sensor + 57040 Actuator Description The 59040 Press-Fit Firecracker Reed Sensor is a small, cylindrical reed sensor 31.0mm (1.22”) long that presses into a 9.5mm (.375”) diameter hole with a choice of normally open, normally closed or change-over contacts. It is capable of switching up to 200Vdc at 10W and is available with a range of sensitivity, cable length, plastic housing color (white, black, and wooden brown), and connector options. It has three crush ribs along the length of the capsule that allow a firm and fixed press-fit. It is well suited for position and limit sensing, security, level sensing applications. It functions best with the 57040 actuator. Sensor Actuator Note: The 57040 Actuator is sold separately. Features Agency Approvals Agency Agency File Number • Magnetically-operated press-fit proximity sensor •Cylindrical capsule with retaining ribs •Operates and mounts through nonferrous materials such as wood, plastic or aluminum •Hermetically sealed contacts •Customer-defined sensitivity options available •Custom cable length and connector options available •Press-fits into a standard drill size hole of 9.5mm (.375”) diameter E61760 Benefits Note: Contact Littelfuse for specific agency approval ratings. •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 highmoisture and contaminated environments Dimensions Dimensions in mm (inch) Sensor 10.70 ±0.25 (.42 ±.01) 8.46±0.25 (.333±.01) 31.00±0.25 (1.22±.01) 300 (11.81) Applications • Position and limit sensing • Security Actuator •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 nonactivated state •Reed contacts last for millions of operating cycles under microcontroller voltage and current logiclevel loads • Appliances • Industrial 8.46±0.25 (.333±.01) 10.70 ±0.25 (.42 ±.01) 31.00±0.25 (1.22±.01) Notes: 1. The 59040 Sensor and 57040 Actuator are designed to fit into a drill size hole of 9.5mm (0.375") diameter. 2. Not recommended to be mounted within ferrous metal materials. The activate distance will decrease significantly. © 2016 Littelfuse Revised: 03/02/16 Specifications are subject to change without notice. littelfuse.com Reed Sensors Firecracker > 59040 59040 Press-Fit Firecracker Reed Sensor + 57040 Actuator Electrical Ratings Contact Type Normally Open Change Over Normally Closed Switch Type 1 3 4 VA/Watt - max. 10 5 5 Vdc - max.

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 11.81in 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, adding a special connector, or plastic housing color options, please contact Littelfuse. 9. Custom sensitivity options and a normally open high-voltage switch option are available.
