P160-LM2 Pogo Spring Test Probe Pin

P160-LM2 Pogo Spring Test Probe Pin provides a reliable, temporary electrical connection for testing electronic components and circuits. Engineers and technicians use this versatile spring-loaded pin to create “bed of nails” test fixtures for quality assurance, prototyping, and in-circuit testing of printed circuit boards (PCBs). Its precision-engineered design ensures a consistent and low-resistance contact, even on uneven or oxidized surfaces, making it an essential tool for high-volume manufacturing and diagnostics.

Key Features:

• Spring-Loaded Plunger: The internal spring maintains a constant contact force, compensating for variations in board thickness or test point height.
• Sharp, Pointed Tip (LM2): The sharp tip design effectively pierces through solder residue, flux, or contamination to ensure a reliable electrical connection.
• Replaceable Design: The probe can be quickly and easily replaced within its receptacle, simplifying maintenance and repair of a test fixture.
• High-Current Capability: Handles significant current loads, making it suitable for both signal and power testing applications.
• Low Contact Resistance: Ensures accurate test results by minimizing voltage drop and signal degradation.

Technical Specifications:

• Recommended Current Rating: Up to 3.0 A
• Contact Resistance: Less than 50 mΩ
• Spring Force: ~150 g at full compression
• Plunger Travel: ~4.0 mm
• Working Travel: ~2.5 mm
• Mounting Receptacle: P160 series receptacle (not included)

Mechanical Specifications:

• Pin Material: Phosphor bronze, gold-plated
• Spring Material: Music wire, gold-plated or stainless steel
• Tip Style: Pointed (LM2)
• Installation: Press-fit into a receptacle (solderless connection)

Dimensions:

• Probe Length: ~24 mm (excluding receptacle)
• Plunger Diameter: ~1.36 mm
• Receptacle Diameter: ~1.7 mm
• Receptacle Hole Size: Recommended 1.74 mm to 1.75 mm

Installation and Use:

• Receptacle Wiring: Solder the receptacle to your test fixture’s circuit board or wire.
• Pin Insertion: Simply insert the Pogo pin into the receptacle’s open end. The press-fit design secures the pin.
• Connection Note: The pin makes an electrical connection with the internal wall of the receptacle, which is soldered to your test circuit. This allows for easy replacement of the probe without desoldering.

Datasheet Reference:

• Refer to the official P160-LM2 Spring Test Probe Datasheet for detailed specifications, force-stroke diagrams, and recommended mounting instructions.

Applications:

• PCB Testing: Create custom test jigs for both in-circuit and functional board testing.
• Battery Charging: Use as a reliable contact for charging portable devices like smartwatches or earbuds.
• Device Programming: Establish temporary connections for programming microcontrollers or flashing firmware.
• Signal Acquisition: Probe test points to monitor voltage or signal integrity on a circuit.

Equivalent Models:

• P50-B1: A common, smaller-diameter pogo pin for finer pitch applications.
• P75 Series: Pins with a slightly larger diameter for robust connections.
• GKS Series: A widely used brand for test probes, offering various tip styles and sizes.
