59040 Press-Fit Firecracker Reed Sensor + 57040 Actuator

Description

The 59040 Press-Fit Firecracker Reed Sensor is a small, cylindrical reed sensor

31.0mm (L) x 10.7mm (Dia.) (1.22” x 0.420”) with a choice of normally open,

normally closed or change-over contacts. It is capable of switching up to 300Vdc

at 10W and available with a range of sensitivity, cable length and connector

options. It is well suited for position and limit sensing, security, level sensing and

linear actuator applications. It functions best with the 57040 actuator.

Note: The 57040 Actuator is sold separately.

Actuator

Features

• Magnetically-operated proximity

sensor

• Cylindrical capsule with retaining

ribs

• Operates through non-ferrous

materials such as wood, plastic or

aluminum

• Hermetically sealed contacts

• Options of normally open, normally

closed or single-pole-double-throw

• Customer-defined sensitivity

• Custom cable length and connector

options available

Benefits

• Ribs on capsule compress when

inserted into a mounting hole and

provide retaining force, allowing

simple and secure press-fit

installation

• Quick and easy press-fit installation

that requires no screws, brackets,

nor glue.

• Non-contact solution, aesthetically

more appealing than push-button or

lever mechanical-type switches

• Ideal for battery-powered

applications as the contacts do not

draw power when in the non-

activated state

• Reed contacts last for millions of

operating cycles under micro-

controller voltage and current logic-

level loads

• Linear actuators

Notes:

1. The 59040 Sensor and 57040 Actuator are designed to fit into a drill size hole of 9.5mm

(0.374") diameter.

2. Not recommended to be mounted within ferrous metal materials, these activate distance

will decrease significantly.

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 sensitivity options and a normally open high-voltage switch option are available.

3. Not recommended to be mounted within/near ferrous metal materials; if doing so, these

activate distances will decrease significantly.
