**Reed Sensors** Flange Mounting Sensor > 59145 ## 59145 Flange Mount Senso ~~r + 57145 Actuator~~ ## **Description** The 59145 is a flange mounting reed sensor 28.57mm x 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 and the wires exit from top right hand side. It is also available with left hand exit - see 59150 Series. It is capable of switching up to 265Vac/300Vdc at 10VA. The 59145 functions best with the matching actuator 57145-000. ## **Note: The 57145 Actuator is sold separately.** ## **Features** ## **Agency Approvals** **==> picture [173 x 9] intentionally omitted <==** **----- Start of picture text -----**<br> Agency Agency File Number<br>**----- End of picture text -----**<br> |E61760<br>~~a~~| |---| ## Note: Contact Littelfuse for specific agency approval ratings. - Customer defined sensitivity option - Two-part magnetically operated proximity sensor - Choice of cable and connector ## **Benefits** - No standby power requirement - Hermetically sealed, magnetically No standby power requirement operated contacts continue to • Operates through non-ferrous operate long after optical and other materials such as wood, plastic or technologies fail due to aluminium contamination • Simple installation and adjustment - Simple installation and adjustment ## **Dimensions** Dimensions in mm (inch) **==> picture [252 x 357] intentionally omitted <==** **----- Start of picture text -----**<br> 28.57<br>(1.125)<br>9.53<br>14.28 Tae (.375) ;<br>(.562) 19.05<br>(.75)<br>15.88 3.43<br>(.625) 3.18x7.82 (.135)<br>(.125x.308 LG.)<br>SLOT 2 6.35<br>Note: 59145 shown. 59150 leads exit opposite. 1 PE| 1 (.259)<br>300<br>28.57 (11.81)<br>(1.125)<br>6.35 (.250) NOM.<br>——<br>9.53<br>14.28 (.375)<br>(.562) 19.05<br>| a (.75)<br>(.125x.308 LG.) e 3.18x7.82 (.625)15.88 o (.250)6.35 4H L (.135)3.43<br>SLOT 2<br>6.35<br>(.259)<br>Schematics Switch Type<br>Black<br>1 and 2<br>co Black<br>Black<br>—— BlueWhite 3<br>Black<br>4<br>Black<br>ee<br>© 2015 Littelfuse Revised: 10/29/15<br>Specifications are subject to change without notice.<br>**----- End of picture text -----**<br> ## **Applications** - Position and limit sensing - Security system switch - Linear actuators - Door switch littelfuse.com **Reed Sensors** Flange Mounting Sensor > 59145 **==> picture [93 x 32] intentionally omitted <==** ## 59145 Flange Mount Senso ~~r + 57145 Actuator~~ ## **Electrical Ratings** **==> picture [507 x 263] intentionally omitted <==** **----- Start of picture text -----**<br> Normally Normally Open Change Normally<br>Contact Type<br>Open High Voltage Over Closed<br>Switch Type 1 2 3 4<br>Contact Rating [1] VA/Watt - max. 10 10 5 5<br>Switching [2] Vdc - max. 200 300 175 175<br>Voltage [4] Vac - max. 140 265 120 120<br>Breakdown [3] Vdc - min. 250 400 200 200<br>Switching [2] Adc - max. 0.5 0.4 0.25 0.25<br>Current [4] Aac - max. 0.35 0.30 0.18 0.18<br>Carry Adc - max. 1.2 1.4 1.5 1.5<br>Contact, Initial Ω - max. 0.2 0.2 0.2 0.2<br>Resistance [5]<br>Insulation Ω - min. 10 [10] 10 [10] 10 [9] 10 [9]<br>Capacitance Contact pF - typ. 0.3 0.2 0.3 0.3<br>Temperature Operating °C -40 to +105 -20 to +105 -40 to +105 -40 to +105<br>Product Characteristics<br>Operate Time [6] ms - max. 1.0 1.0 3.0 3.0<br>Release Time [6] ms - max. 1.0 1.0 3.0 3.0<br>Shock [7] 11ms 1⁄2 sine G - max. 100 100 50 50<br>Vibration [7] 50-2000 Hz G - max. 30 30 30 30<br>**----- End of picture text -----**<br> Notes: 1.

Founded in 1927 and headquartered in Chicago, Illinois, Littelfuse is a premier global manufacturer of circuit protection, power control, and sensing technologies. Widely recognized for pioneering the first small, fast-acting protective fuse, the company has grown into an industry leader whose highly reliable components are essential to modern industrial, transportation, and consumer electronics applications worldwide. At the core of the Littelfuse portfolio is an expansive and industry-leading range of circuit protection solutions. This encompasses a massive selection of traditional fuses, fuse holders, and resettable PTC thermistor fuses designed to safely interrupt overcurrent conditions. To defend against electrical overstress, Littelfuse also provides advanced transient voltage suppression (TVS) technologies, including thousands of specialized TVS diodes, TVS varistors, and gas discharge tubes (GDTs) that ensure robust defense against voltage spikes and environmental hazards. Beyond its foundational protection components, Littelfuse manufactures a diverse array of discrete semiconductors, sensors, and switching devices. Engineers rely on their high-performance thyristors, including TRIACs and SCRs, alongside power-efficient Schottky diodes and MOSFETs for demanding power control applications. Complemented by precision proximity sensors and highly reliable reed and solid-state relays, Littelfuse delivers the critical building blocks required for secure, efficient, and complete system design.
