Relays, Optocouplers & Repair Passives
Industrial relays, optocouplers, thermistors, varistors, film capacitors, high-voltage capacitors. Small-batch friendly — one relay or one hundred.
What We Source
Industrial Relays
General purpose, power, signal, and safety relays. Coil voltages: 5V, 12V, 24V, 48V, 110V, 230V AC/DC. SPDT, DPDT, 3PDT, 4PDT. Plug-in and PCB mount. Finder, Omron, Schneider, TE, Hongfa equivalents.
Optocouplers & Solid State Relays
Phototransistor, phototriac, and photodarlington optocouplers. DIP and SMD packages. Panel-mount and PCB-mount SSRs. Input: 3-32V DC. Output: 24-480V AC, 5-60V DC. Zero-cross and random-fire types.
NTC & PTC Thermistors
NTC: 1k, 5k, 10k, 100k ohm at 25°C. B-values: 3435, 3950, 3977. Glass-encapsulated, epoxy-bead, ring-lug types. PTC: overcurrent protection and temperature sensing.
MOV Varistors & Surge Protection
Metal oxide varistors. Voltage ranges: 14V to 1100V. Disc sizes: 5mm, 7mm, 10mm, 14mm, 20mm. For AC mains surge protection and DC circuit protection.
Film & High-Voltage Capacitors
Polypropylene (PP), polyester (PET), and polycarbonate film capacitors. High-voltage ceramic capacitors (1kV-15kV+). For power supplies, snubber circuits, and resonant circuits.
Terminal Blocks & DIN Rail Accessories
Feed-through terminal blocks, fuse holders, disconnect terminals, earth terminals. Compatible with Phoenix Contact, Weidmuller, Wago, and other DIN rail systems.
Sourcing Capability
Relay Specs We Match
Coil voltage (AC/DC), contact rating (10A, 16A, 30A+), contact configuration (SPDT, DPDT, 4PDT), socket/plug-in type, and PCB footprint. Send the part number or a photo.
Passive Component Matching
We match capacitance value, voltage rating, tolerance, temperature coefficient, and physical package size. Send markings or a photo — we identify and cross-reference.
MOQ
Very small-batch friendly. Single-piece relay matching for equipment repair. Small quantities of passives (10-100 pcs). Bulk pricing available for production quantities.
Frequently Asked Questions
Can you match a relay from just a photo? ▼
Yes, in most cases. Send a clear photo showing the relay markings. If the markings are worn, also tell us the equipment model it came from. We can identify relays from partial markings and circuit context.
Do you sell single pieces for repair? ▼
Yes. We understand industrial repair often needs just one or two relays. No minimum quantity for most relay types. We also source single quantities of specific passives for board-level repair.
What relay brands do you cover? ▼
Finder, Omron, Schneider Electric, TE Connectivity, Hongfa, Panasonic, Fujitsu, Song Chuan, and many others. We can also cross-reference to compatible alternatives.
