Substitute Part Grouping Explanation

Substitute identification for the HTB18-A4A2BE is based on electrical and mechanical parameter equivalence within the SureSense series. The primary substitute, HTB18-B4A2BH, maintains identical specifications across all critical functional parameters: sensing distance range, supply voltage, response time, output configuration, light source wavelength, connection interface, ingress protection rating, and adjustment mechanism. Both sensors operate within the same temperature range and employ identical sensing methodology. The substitution is valid because the HTB18-B4A2BH preserves all electrical and mechanical characteristics that determine sensor performance in detection applications.

Key parameters governing substitution:

• Sensing distance: 0.197" ~ 11.811" (5mm ~ 300mm)
• Supply voltage: 10V ~ 30V
• Output configuration: NPN/PNP
• Light source: Red (631nm)
• Connection: M12 connector
• Ingress protection: IP67, IP69K
• Response time: 500µs
