Holding solenoid WL 0735

self-holdingcompactbistable

Overview
Magnetic latching solenoids are open-frame linear solenoids incorporating permanent magnets to hold the plunger position without continuous power. They are designed for low-energy, battery-powered or remote applications where maintaining position with minimal heat and power consumption is required.

Unit Features
Operation is bi-stable: a short drive pulse moves the plunger and the permanent magnet then holds it mechanically without supply current. The WL 0735 is an open-frame pull/push unit suitable for integration into compact devices; customization of plunger end, terminals and mounting holes is available subject to MOQ.

Applications

• Smart locks & access control: electronic door locks, parcel lockers, hotel locks, vending doors — chosen for low standby power and secure hold on power loss.
• Industrial automation: position locking, sorting/dispensing systems, safety interlocks, mechanical hold actuators — maintains position without continuous current.
• Automotive systems: fuel door locks, EV charging port locks, latch controls — reduces battery load and heat.
• Medical devices: portable diagnostic units, drug dispensers, medical cabinets — suitable for battery-operated equipment.
• IoT & smart devices: smart cabinets, automated drawers, appliance locks — energy-efficient state holding.
• Payment & vending: ticket machines, POS locking modules, ATM mechanisms — retains state without continuous electricity.
• Energy & utilities: smart meters, breaker locks, remote relays — lowers long-term power consumption.

Advantages and Disadvantages

• Advantages: zero holding current, low heat dissipation, long service life, fast response, bi-stable operation suitable for battery-powered equipment.
• Disadvantages: requires pulse control or polarity reversal to change state, polarity sensitivity, more complex drive electronics, higher initial cost versus simple solenoids.

Additional Notes
Designed for OEM customization of force, stroke, voltage, size, mounting and terminations subject to minimum order quantities. Latching operation typically uses short pulses (e.g. 20–200 ms) and may require driver circuitry (H-bridge or polarity-reversal) depending on latching type.
