Introduction to Photoelectric Sensor Chips
Photoelectric sensor chips are critical components in modern industrial automation, converting light signals into electrical outputs for object detection, distance measurement, and position sensing. These chips are used in manufacturing lines, robotics, and safety systems. Prices vary significantly based on technology type (through-beam, retro-reflective, or diffuse), sensitivity range, output type (PNP/NPN, analog), and package size. This article provides a detailed price list for common photoelectric sensor chips, focusing on high-volume procurement for OEMs and system integrators.
Low-Cost Photoelectric Sensor Chips (Under $2.00)
For basic applications like simple object presence detection in packaging or conveyor systems, budget-friendly chips are available. The Vishay TEPT5700 is a phototransistor-based chip with a 5mm wavelength sensitivity, priced at $0.45 per unit in bulk (1,000+ pieces). The Sharp GP2Y0A21YK0F analog distance sensor, using infrared with a 10-80cm range, costs $1.20 each for 500-unit orders. The Omron EE-SX670 micro-sensor, with a 5mm slot gap, is priced at $0.85 per chip for small quantities. These chips offer basic digital output (ON/OFF) and are ideal for cost-sensitive projects.
Mid-Range Photoelectric Sensor Chips ($2.00 to $8.00)
Mid-range chips provide enhanced performance such as longer detection range, higher speed, or ambient light rejection. The Hamamatsu S1133 PIN photodiode array, with a spectral range of 320-1100nm, costs $3.50 each for 100-unit orders. The Panasonic CX-411-B polarized retro-reflective sensor chip, with a 4m range, is priced at $4.20 per unit in small lots. The STMicroelectronics VL53L0X laser-ranging sensor (time-of-flight) offers 2m range and I2C interface, costing $3.80 each for 50-unit purchases. These chips are suitable for industrial sorting, elevator doors, or automated storage systems.
High-Performance Photoelectric Sensor Chips ($8.00 to $25.00)
For demanding environments requiring high speed, precision, or immunity to dust and vibration, premium chips are available. The Keyence FU-35TZ fiber optic amplifier chip, with a response time of 50μs, costs $12.00 each for 10-unit orders. The Sick WTB4-3P2242 background-suppression sensor chip, with a 20-300mm adjustable range, is priced at $15.50 per chip. The Balluff BOS01E6 photoelectric sensor chip with IO-Link communication costs $22.00 each for 5-unit lots. These chips support complex functions like teach-in, hysteresis control, and are used in high-speed bottling or automotive assembly lines.
Specialty and Custom Photoelectric Sensor Chips (Over $25.00)
Custom-designed chips for niche applications, such as underwater detection or explosion-proof zones, command higher prices. The Pepperl+Fuchs ML100-55/103/115 through-beam sensor chip with a 20m range and anti-glare filter costs $28.00 each. The Banner Q4X laser sensor chip with analog output and stainless steel housing is priced at $35.00 per unit. For specialized requirements, like high-temperature operation (up to 100°C) or multi-zone detection, chips like the Cognex IS5703 smart camera sensor chip can cost $50.00 to $100.00 each. These are often used in pharmaceutical inspection or heavy machinery safety monitoring.
Price Comparison and Procurement Tips
When comparing prices, consider total cost of ownership including packaging, calibration, and warranty. Bulk orders (1,000+ chips) typically provide 20-40% discounts from listed prices. Distributors like DigiKey, Mouser, and RS Components offer real-time inventory and tiered pricing. For OEMs, direct factory contracts with manufacturers like Omron or Keyence can reduce costs by up to 50% for annual volumes exceeding 10,000 units. Always verify compliance with industry standards (e.g., IP67, CE, RoHS) before ordering. Use the table below for quick reference:
- Budget chips: $0.45-$1.20 (Vishay, Sharp)
- Mid-range chips: $2.00-$8.00 (Hamamatsu, ST)
- High-performance chips: $8.00-$25.00 (Keyence, Sick)
- Specialty chips: $25.00-$100.00 (Pepperl+Fuchs, Banner)
