Guardmaster 440P Safety Pads

The Allen-Bradley Guardmaster 440P is a family of safety limit switches and position sensors designed for machine guarding and safety interlock applications on industrial equipment. The catalog-number structure encodes actuator type, contact configuration, output method, and connection style in a compact alphanumeric string: the first characters after the bulletin prefix identify the actuator style — A for standard body variants, C for metal-body IEC full-switch formats, M for miniature plastic IEC versions — followed by characters indicating the actuator head (e.g., SL=short lever, RP=roller plunger, MH=metal head), contact configuration (B02=BBM 2 N.C., S11=1 N.C./1 N.O.), and termination type (C=cable out bottom, CS=cable out side, D4=4-pin DC Micro connector, D5=5-pin DC Micro connector, E=M12). Notable in-stock models include the 440P-ASLB02C (short lever, BBM, 2 N.C., 2 m cable), the 440P-ARPB02D4 (roller plunger, 4-pin Micro connector), the 440P-CRPM12E (metal-body IEC roller plunger, M12), and the miniature-format 440P-M18001.
