Core Advantages
SPDT and DPDT options defined by model
JPK-6/055 provides one high-voltage changeover path, while JPK-11/008 provides two-pole transfer with frequency-rated data. In unattended systems and replacement projects, using the complete model number helps prevent substitution with a visually similar but electrically different relay.
Measurable limits for open and closed states
Both models state minimum insulation resistance for the open state and maximum contact resistance for the closed state. These values give unattended high-voltage circuits clear acceptance points for leakage and closed-path voltage drop.
Published environmental and life ratings
Both models operate from -55 to +125 deg C and include shock, vibration, and mechanical-life data. Mobile, remote, and vibration-exposed equipment can be checked against these stated limits instead of a general reliability description.
Customization
Electrical configuration
Working voltage, withstand voltage, carry and switching current, contact form, coil voltage, and pickup and release requirements.
Performance targets
Contact-resistance limit, switching response, operating duty, and the application conditions used to approve the sample.
Mechanical interface
Enclosure size, terminal arrangement, mounting method, and modification from JPK-6-055, JPK-11-008, an approved drawing, or a reference sample.
Quality Control
Incoming components are checked for dimensions, material condition, surface quality, and fit with the confirmed model. Before vacuum sealing, technicians verify the contact unit, its relationship with the coil, the terminal connection, and the ceramic-to-metal assembly so the internal geometry is correct before furnace processing.
Electrical inspection checks contact-resistance consistency, insulation, withstand voltage, coil operation, and repeatable switching response. Aging and stabilization are used to identify drift before shipment. Final inspection confirms the model, enclosure, terminals, mounting interface, label, and recorded test results.
Why Choose Us
Long-term electro-vacuum product development
Over more than five decades of production, Wanping's vacuum product series has received 45 national, ministerial, and provincial-level outstanding-product awards.
Assembly controlled model by model
Contacts, coils, terminals, ceramic dimensions, and mounting interfaces are tied to the exact relay model so visually similar but electrically different assemblies are not substituted.
Aging before shipment
Vacuum component maturation equipment is used to identify unstable contact, coil, or insulation behavior before the relay is installed in the customer's equipment.
FAQ
Q: Can a reference sample be used for development?
A: Yes. The reference sample is measured and compared with the required voltage, current, coil, contact form, terminal layout, and mounting conditions. The approved drawing and specification then become the production basis.
Q: How is the relay protected during transport?
A: The ceramic enclosure, terminals, leads, and mounting parts are separated and cushioned to prevent impact, bending, and terminal stress. The outer packaging is selected according to the quantity and shipping route.
Q: Which operating conditions have the greatest effect on switching consistency?
A: Coil overvoltage, operation above the make/break rating, inductive transients, excessive cycling, vibration, terminal stress, and incorrect mounting have the greatest effect on repeatable switching.
Q: How can false operation be reduced in the equipment?
A: Use the specified coil voltage, suppress inductive transients, keep control wiring away from strong interference sources, secure the mounting interface, and select a contact form that matches the circuit's required fail state.
