(1.00” x 0.245”), with a choice of normally open, normally closed or change-over contacts. It is capable of switching up to 265Vac/300Vdc at 10VA. The 59025 Firecracker Reed Sensor is available with a range of sensitivity and cable length options. It functions best with the 57025 actuator. ## **Note: The 57025 Actuator is sold separately.** ## **Features** ## **Agency Approvals** - Magnetically-operated proximity sensor - Hermetically sealed contacts - Operates through non-ferrous materials such as wood, plastic or aluminum - Customer-defined sensitivity option - Custom cable length and connector options available - RoHS compliant **==> picture [173 x 33] intentionally omitted <==** **----- Start of picture text -----**

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 sensitivities and a high voltage switch are options ## **Sensitivity Options (Using 57025 Actuator)** **==> picture [507 x 109] intentionally omitted <==** **----- Start of picture text -----**
