59070 M8 Plastic Threaded Barrel Sensor + 57070 Actuator
Description
The 59070 is a small plastic barrel sensor with a M8 x 1.25 thread, 38.1mm
(1.500”) 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 functions best with the 57070 actuator.
Note: The 57070 Actuator is sold separately.
Features
• Two-part magnetically operated
proximity sensor
• Threaded barrel with retaining nuts
• Available as M8 (57070/59070) or
5/16 (57065/59065) size options
• Customer defined sensitivity option
• Choice of cable length and
connector

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.
