		TOP > Products > Latching solenoid   Latching solenoid   Latching solenoid is a solenoid using permanent magnet for magnet circuit. It uses holding power of permanent magnet attraction to hold position, which results in energy saving. There are "bistability solenoid" and "monostable solenoid" according to circuit differences.   1.Suction with direct current power. Suction by turning on electricity to the coil for suction, electrification finishes and continues retention by holding power of the permanent magnet after electrification is cut. Holding power of the permanent magnet is demagnetized by turning on electricity to the coil for demagnetization. 2.It continues retention by holding power of the permanent magnet. Even at a power failure, the present position is hold and lock mechanism is unnecessary Because current to hold the position is not needed, there is no worry such as coil temperature rise and heat generation and power saving. 3.Low cost type Series comparative table   Type Series Features Bistable Standard type TSB series TSB-0705 TSB-0805 TSB-1005 TSB-1010 TSB-LS It moves forward and backward only with the electrification of the coil and it continues retention by holding power of the permanent magnet bidirectionaly. It is the bi-directional latching solenoid. The best the use at the position of flapper(gate), shutter driving and switching where holding power is necessary in money and bank machineries and optical equipment. Mono stable Standard type TSBP series TSBP-09BN1 Suction with coil electrification, and it continues retention by holding power of the permanent magnet even after electrification is cut. Single side type. The best for the use tube holder of medical equipment and selector of textile machineries.   Series list   DC resistance Outside dimension(mm) stroke Non excitating holding power TSB-0705 10Ω 16 ・ 16 ・ 35.7 5mm Over3N TSB-0805 7.5Ω 20 ・ 20 ・ 30 5mm Over5N TSB-1005 20Ω 25 ・ 25 ・ 45 5mm Over15N TSB-1010 20Ω 25 ・ 25 ・ 45 10mm Over10N TSB-LS 5Ω 25 ・ 25 ・ 45 5mm Over2N TSBP-09BN1 Suction10.5Ω Return14Ω 25 ・ 25 ・ 38 -5mm Over20N   Please refer to each product page about the defailed dimensions.     　     Drive system ■drive system of TSB series With SW1 switch ON, it absorbs on primary coil side, resets the switch and still keeps the position.   With SW2 switch ON, it absorbs on secondary coil side, resets the switch and still keeps the position. R is external addition resistance (retention side, for demagnetization current value setting)   ■Example of circuit of TSB series (reference) As for the circuit to drive the latching solenoid, our customers have devised variously, but reference example is shown on description below.
