Linear 2500-185 Terminal Strip 13-142 Kulka Product Overview
The Linear 2500-185 is a 13-142 Kulka terminal strip used as a replacement connection block in select Linear / OSCO gate operator control and power assemblies. Terminal strips keep field wiring and internal wiring organized so each circuit lands at the correct point. When a terminal strip becomes loose, cracked, heat-damaged, or corroded, the operator may show intermittent accessory faults, limit problems, safety input issues, or no-run conditions that can be difficult to trace.
This terminal strip must be matched by part number and layout. Similar terminal strips can have different numbers of positions, mounting holes, spacing, numbering, jumper arrangements, and current ratings. Swapping in a different block without matching the diagram can misplace wires or create unsafe connections. For older Linear / OSCO operators, take clear photos and label every wire before removing the old strip.

Technician Note
Before removing the old terminal strip, photograph every wire and label both sides of the connection. Many operator problems after terminal replacement come from wires being landed one position off.
Before Ordering
- Confirm the exact Linear part number in the parts diagram
- Compare terminal count, spacing, and mounting style
- Label all wires before disassembly
- Inspect for heat damage or corrosion in the surrounding wiring
- Do not change jumper or wire positions unless the diagram requires it
Professional Advisory
Terminal strip replacement can involve line-voltage and low-voltage circuits in the same cabinet. Power should be disconnected and wiring should be verified by a qualified gate technician.
Important Ordering Warnings
Do not guess wire positions from memory. Miswired terminal strips can damage boards, accessories, motors, or safety circuits.
Product Questions & Answers
What is the Linear 2500-185 used for?
It is a replacement 13-142 Kulka terminal strip for select Linear / OSCO gate operator electrical assemblies.
Can I use a terminal strip with the same number of screws?
Not automatically. Mounting, spacing, markings, current rating, and jumper layout may differ.
What should I do before disconnecting wires?
Take clear photos, label each wire, and compare the old strip to the operator wiring diagram.
Can a bad terminal strip cause intermittent gate problems?
Yes. Loose, corroded, cracked, or overheated terminals can create intermittent faults and voltage drop.
Does this fit every Linear operator?
No. Use it only where the parts diagram calls for this part number or matching terminal strip reference.
