Check your position-detecting equipment is up to scratch with this Banner beam tracker. By sending and receiving infrared light, the unit checks that photoelectric sensors (855-8320) are in working order to keep processes ticking over. With its flashing LED indicator, the device clearly signals a laser's beam intensity to take the hassle out of inspections. Finding kit to use the product with is no issue, as it works with sensors from many suppliers. As the module detects high EMI levels, it's a sound choice for pinning down sources of heavy electrical noise.
