Agency Approvals
Agency Agency File Number
19.05mm x 6.35mm (1.125” x 0.750” x 0.259”) with a choice of normally open,
normally open high voltage, normally closed or changeover contacts. It’s case
design enables screw or adhesive mounting. It is rated for operation up to 150°C.
It is capable of switching up to 265Vac/300Vdc at 10VA. The 59135 functions
best with the matching actuator 57135-000.
Note: The 57135 Actuator is sold separately.
Features
• Two-part magnetically operated
proximity sensor
• High temperature rated
• Cross-slotted mounting holes for
optimum adjustability
• Customer defined sensitivity option
• Choice of cable length and
connector
• Thermoset overmold material
• Teflon insulated wires

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.
