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. 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. © 2019 Littelfuse Revised: 04/29/19 Specifications are subject to change without notice. littelfuse.com **Reed Sensors** Push Button Sensor > 59250 **==> picture [93 x 32] intentionally omitted <==** **==> picture [93 x 32] intentionally omitted <==** ## 59250 Seating Occupancy ~~Reed Switch Sensor~~ **==> picture [507 x 325] intentionally omitted <==** **----- Start of picture text -----**
