59060 Stainless Steel M8 Threaded Barrel Sensor + 57060 Actuator
Description
The 59060 is a small stainless steel barrel sensor with an M8 x 1.25mm pitch
thread, 36mm (1.420”) long with a choice of normally open, normally open high
voltage, normally closed or change over contacts. It is capable of switching up to
265Vac/300Vdc at 10VA. It has a variety range of sensitivity, cable length and
connector options. It functions best with the 57060 actuator.

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.
